- Barry is back at it with a video showing you how to properly bypass your on board computer or OBC on your Club Car Precedent golf cart. Some aftermarket battery chargers do not require the use of the On-Board Computer so this video should be helpful in those cases.
An OBC is a computer that Club Car decided to put on the cart instead of the charger like other cart manufacturers. Club Car has a charger that consist of a simple transformer and rectifier assembly with no controls for charging inside the external charger. It is very simple to bypass using this how to video. Some of the DPI aftermarket chargers we sell do require an OBC and others do not. 15amp charger will utilize on board charger while our 17 amp models do not require it. If you are in the market for a battery charger and don't want to worry about replacing your OBC down the road you might benefit from bypassing it and purchasing the 17 amp model. Please subscribe to our channel for other how to videos and be sure to visit our website for all you golf cart parts and accessory needs.
Thanks Barry. This video saved the day on my 16 year old Club Car Carryall VI. The OBC would not allow my Club Car EIRC charger to connect, but after this simple modification, the EIRC charged my new Trojan T-875 batteries without issue.
Thank you Barry, you do great easy to understand videos. One question my Club Car Precedent is 2007 model, and 48 Volt. Once I cut the Neg from the Charging Harness, what Neg terminal do I need to attache the spliced on Eyelet to on my 48V model. Thank you
Barry, Thank you for your great videos, I have 2006 CC 48volt, I put new batteries in it, runs good but will not take a charge, I have been charging each battery, Is there a way to test the OBC? or Charger? or plug? to determine which the problem? Do you recommend bypassing the OBC and going with a smart charger or replacing the OBC? after determining where my problem is. Thank you.
Great informative video, thanks!
The black negative goes to which battery negative in a 4 battery 48 volt configuration?
If you swap out your lead acid batteries with lithium what else is messasary (other than getting a new 48 volt lithium friendly battery charger.
Barry, nice video. I have a 2018 club car precedent. I don’t see a OBC on this cart in the location yours was. Could it be in a different location?
Do you use the same process on a Precedent that uses 4-12v batteries? Thank you
Hi Barry. I just did what you said and it is still not charging. I watched another video and it says that the gray wire needs to be deleted, and the white and blue wires need to be jumped together. What do you think?
Thanks for the video it was very useful. I am installing a lithium battery and I need to bypass the OBC for the new charger. I have heard just to disconnect the lead you cut and place of the negative. Can I just disconnect it only? If I have cut it and connect it to the negative can someone tell me why? Thanks again.
Berry how about a video on installing a lithium battery kit in a 2005 48v precedent club car . Thanks
The video was very good explaining about bypassing the OBC but you you left out a very crucial point in which this information is very bright, you didn't explain why would you bypass the OBC, what problem persists when the OBC goes bad or what issues are you having in the golf cart to make the OBC a suspect,
Ok what is "Battery - 6 mean." Had he said Battery - ... Taking the first cable off, he pointed to what you later called called Battery -6
Thanks for the video, I’m changing out all my battery cables to 2 ga. and my negative that’s on B- terminal has 3 wires coming out. Can you tell me what to do with the other 2 wires or do I have to have multiple wires on new neg. cable?
Thanks Barry for all yor time Im from Monterrey Mexico
JOSE FELIPE CRUZ SIFUENTES hola oye me podrias ayudar en algo?
@@PeinadosDamaris28 Que ocupas, Saludos
Can I still charge overnight and go home after bypassing the OBC?
If I disable the OBC or On Board Computer
on my 2006 Club Car Precedent, can I use a
LINKS Series charger EPS by Lester Electric to charge my cart? Thank you.
How long do you typically charge a 48v carts for now that the OBC is gone? I have a power drive 2 charger and a
2011 club car precedent 48v. You helped me resolve my issue. I just made a jumper from the grey wire that normally goes to the OBC from the charger receptical. I left the fuse in path and jumped the new wire assembly to number 6 neg. My power drive 2 charger kept short cycling and dumping the charge after 5 or 6 minutes. I thought it was the charger. So, I replaced the rectifier, relay and fuse in the charger. The charger doesn't dump a charge anymore and runs around 8-9 amps.
Hi Barry thanks for the info, battery charger now charges but will not turn off, it continually runs at approx 15 amps and batteries reach a charge voltage of 58 volts, i assume the OBC originally turns it off once correct voltage has been reached.does the charger have voltage reading capabilities as well? All my batteries are new but am concerned about cooking them. thanks Greg from Australia.
Hi Barry. Great video. I have a 2015 club car precedent and my original charger burned out. I bought a deltaqIC650 charger (set to charge program .003 for my T875 batteries) and it's not charging properly because of OBC incompatibility with my new charger. It seems like this work around should work. Any comments would be helpful. Many thanks. Lewis
I have a 2007 Club Car Precedent and watched your video on how to bypass on board computer. I understand which wire on the on board computer to cut but I don't understand which battery to connect the negative wire to since we only have 4 batteries on our cart.
should be the last battery in the series. the last one usually is the negative going to the controller
I have a 1999, 48V, Club Car DS. I am converting to lithium batteries with an offboard charger. The car was modified by a previous owner. It has a different motor, an Alltrax 4845 controller and an offboard charger. It does not have a run/tow switch. Do I need the OBC?
After storing my cart the batteries got low on fluid because of the heat in AZ. I refilled the batteries and tried to reser and it didn’t work, any help would be appreciated.

Be careful when you charge this set up. Have some sort of timer outlet and surge protector. Or just watch it full time.. DO NOT leave this plugged in you will regret it.
Muy buena información gracias.
Tiene algún vídeo en el que se explique cómo ajustar los parámetros de un controlador 1510-5201 con el programador 1314? Me interesa saber si es posible modificar el freno regenerativo o bajar su intensidad.
Que tenga buen día y gracias
So, I'm a bit confused by this. Every other person says beyond just moving the black wire to negative terminal on #6, that there are addition steps with blue and yellow cables, etc. Even OBC bypass kits come with multiple cables. What is the difference from your method vs the other methods?
All you have to do is go to the back of the charger port and take the black and grey/blue and go straight to main negative on cart that way charger port goes straight to batteries and not obc only downside is if you don't have a new digital charger. If you have the old school heavy sob charger than you have to either put it on a timer or make sure you unplug it because it won't shut off and could do serious damage. The new chargers are a.fifth the weight of the old ones and they have a obc built into it so doing this isn't really a.issue
Do you answer or give advise with golf cart problem?
Thank you
After the modification, can you still use the Club Car OEM charger?
no
@@romanpaine9513 Thx
SO, what charger do i use? I 2am trickle charger for each batter?
hello Barry, can you tell me how to bypass the OBC on a club car ds series 48v (02) cart.........
Hello,
I did exactly what you did and the golf cart charges but does not go
I have replaced the 36 volt on board charger .the new one only has 2 wires . What should I do the third wire on the golf cart . I believe that the wire is to stop the cart being driven whilst charging
Thank you!
Where do you pick up 12 volt for light and key and break s
I have a 2007 48volt Club Car Precedent that will not run but does charge. A friend accidentally arced a battery connection while changing shocks. Is there a reset process for the 2007 Precedent?
From UK. Hi Barry enjoy your videos, very informative. I have a 2004 Club Car electric 48 volts. It only runs at steady relatively slow pace, goes uphill same speed as on flat. Is it governed or speed restricted? And if so where is governor located and can I adjust for little more speed
Cart only used on golf course.
The governor is programmed into controller. If you contact a local CC dealership, they can reprogram the controller for optimal performance.
I'm having a problem with a 2005 presedent that was reversed polarity on the batteries and now the 15 amp fuse blows when switched to run and key is turned on??? any ideas or recommendations on how to proceed
hi
how r you bro
i am from india i am running busniess e vehicals service center i have one golf cart controller which is not working 1515-5201, Speed Controller 48V, 250A Controller for Club Car is not working
Can you tell me how to do a obc delete on a 2009 club car village Lsv 2+2 48v. I'm looked everywhere and can't find anything
Hi, SO are you connecting both cables to the negative terminal now, on top of one another?
Yes.
@@golfcartking Thank You so much. Love your Videos. I have one last question. Does that mean now that I am bypassing, will my battery light still function the same way, and can I still use my E.R.I.C Charger? Happy Fourth!!!!!!!
When you do the bypass will the charger shut down after the batteries are charged or just keep pumping?
It will keep charging
I have a Club Car PowerDrive 3 Golf Cart Charger that I need to connect to a Forklift Battery (2-Prong) Anderson Connector, and I don't know how to connect the 3rd (Blue) wire. Any Comments would be Helpful.
The wiring for a 2003 Club Car Pathway is different. The black wires going to the OBC, controller, and front are all common to a single post, along with a smaller gauge wire (pink and black). Any insight on how to handle this model?
I have the same model and about to perform the bypass. But, the diagram I have shows that both the black and the Grey wires from the back of charging plug need to be removed from the back the OBC and extended with a round terminal added and connected to the last Battery in series negative terminal. One will unplug but the other that has a fuse inline has to be cut. The one with plug is a smaller wire while the one with the inline fuse is a 12 ga wire. A little splice is needed.
Before I do this I will be checking with someone because Barry here only talks about one of those wires being changed out.
Barry- Great videos! I have a 2008 CC Precedent and installed a new alltrax 500amp controller and HD solenoid. I have everything hooked up correctly but in the controller software monitor, it shows the cart is plugged in charging (when it is not) and therefore won't run. The OBC was working fine prior to modifying... Do you think it is a damaged wire (from the install) going to or from the OBC or something else? Thanks for your help!
I would double check the wiring diagram to ensure everything is in the correct spot. Did you make sure to leave the wire going through the middle of the OBC? This is a must. Also, you did put the cart into TOW before starting?
@@golfcartking Thanks for the quick response. Yea I have the new battery cable running through the OBC as it was previously and I had the cart in tow while I was doing all of the changes. I'll double check the wiring diagram. When I go into the alltrax software, all of the monitors look good except for the one flag saying it is charging and there is another one called 'HPD Satisfied' that flickers between True and False. Not sure what that flag means.
@@maxmcardle2750 I'm not quite sure what that means. Give alltrax a call, they like to get involved in troubleshooter their products.
alltraxinc.com/customer-support/
Does anyone know if you do this will it prevent the charger from tripping?
Hi, is it the same process for a 4 battery 2006 precedent model?
Barry do you bypass the OBC if you want to switch to lithium . I would like to install a lithium battery kit and I believe I need to bypass or disconnect the OBC to use a lithium charger ?
Most likely. I know one of the lithium kits says it will use the factory charging system but a lot of them come with their own chargers that don't use the OBC.
Ok what is "Battery - 6 mean." Had you said Battery - ... Taking the first cable off, you pointed to what you later called called Battery -6
can I still use the charger that I used with the obc????
I have a 1995 Club Car with the first three digits of the serial being A95... would this procedure be the same for mine? Thank you very much
Yes, the main thing is to make sure that the negative wire has a main feed to the last negative in the battery pack.
@@barrywilson6665 Thank you very much Barry!👍
What battery number for the 48v set up?
I arced the negative obc wire to bat + 3 wondering what I messed up
Is this that same process for a DS cart?
Thanks for the video - the problem I am having is ... my 36 volt EZ-GO has forward and reverse - and the in both "directions" it goes FULL SPEED ! there is no progressive acceleration. any idea what that might be? thanks much !
That could really be a multiple of different possibilities. Bad ITS, Shorted out field winding in the motor or even a bad controller.
Thanks much! I am a little lost now .. ha! I can't find much about Hyundai Electric Golf Carts .. but it seems to be close the Ez-Go I did purchase the part appears to be linked to the accelerator - a penenti-something .... :) It looks NEARLY identical - it is some type of switch - with a lever that has a switch and spring on it - and a lever that when you acelerate moves the lever about 3 or 4 inches .... I am assuming it graduates the current .. I am not sure how to send a pic on here ... or I would .. thanks again .. gd
I made a video of the part - what do you think? gd
Hey Barry can you do this on a 03 Club Car?
I tried that today and did not work. charger was charging but golf cart did not work and yes it was on the run position
what would cause my club car to not go when i push the pedal the first time then go when i lit it up and push it again
I have a 2014 club car precedent and my controller panel doent have a plate with a wire coming from it where you say the part number is for the obc, i havent taken it apart yet but my question is do i have a obc?
2014 was a change over year, some have it, some don't.
Only 96-13 club cars have obc
I have an 07 IR club car with new batteries and new charger. It's 48V. New batteries and the thing took off like crazy. Now on the charger, it kicks in for 10-15 minutes and shuts off. No gradual decline. Tried charger on identical cart and works fine. If I do the by-pass will automatically charge and slowly ramp back down as the batteries become fully charged?
Doing the bypass allows you to use a smart charger. If you bypass the obc, the charger you have now will not work.
So my new club car charger is a money down the pooper. Ok. Been looking at NOCO Gen 4 to charge all at once. So without removing each cable can I also (waiting for gen 4 to be delivered) charge each battery separate?
Yes , you can charge each battery individually but I would recommend disconnecting the cables.
Is 48v Allready replace control board
I have a 2010 club car and it won't move with pedal. The cart surges a little but won't move. Any insight on what the problem could be?
Barry Wilson thanks for replying so fast. I'll test the batteries. And what is the mcor? I'm new to the golf cart scene
Barry Wilson and how would I go about testing it. I have a multi meter but I can't seem to find a wiring diagram for the unit or how much voltage or resistance I should be seeing at the motor etc
Thank you for the video. Once the OBC negative wire is bypassed directly to negative terminal 6, is the negative wire to the cart reconnected? I ask because the OBC bypass wire is much smaller in gauge, and I thought positive and negative gauge wiring needed to be the same for proper current. Thank you in advance.
I am wondering the same thing. Did you find out?
@@FE428Power You'd put the main negative back on the batter with the new ring terminal on top of it. This just moves the charge port negative to the battery pack instead of the OBC, disabling it.
I have a 96 clubcar ds 48 power drive the charger dose not shut off, will cook the batteries at about 62 volts so I unplug it,it will shut of if I unplug the Grey wire dose that mean my obc is fried?
Barry Wilson thanks
My Cart wont stop charging, it runs permanently. Ive by passed the OBC and still keeps on running. The charger is a Powerdrive which is the same as the CART, any ideas?
Once you bypass the OBC, you have to purchase a smart charger. Another thing is that if you have a weak battery in the pack the charger may run for a lot longer time period.

With this bypass,the charger still auto off when full charge, model PH1331
Hi Barry,
I'm working on a cc AQ 2003 series. If I'm reading the serial number correctly. It will go in reverse no matter what direction you select. It has the black box Curtis controller. Which was replaced since one of my coworkers art across the two motor terminals with a wrench while changing shocks.
I've got the procedure for testing the OBC. Is this bypass used as the same way to see whether or not I have a bad OBC or somebody fry the new controller?
dear sir we have a electric golf car not run same lick a befor . can you halp me
What model is the golf cart and the voltage?
dear sir . model is LVTONG madinchina , Rated speed 18-24km/h, moter power $ Kw, model NO. LT-A.GC
@@mahawadugeperera.999 I do apologize, I have no information on that type of golf cart.
@@golfcartking thank for the reply
I have a 2014 precedent Did it come with an OBC it has the white box
It is a very good possibility that your club car has an OBC. In late 2014 club car starting not putting OBC's in some carts. If the part your looking at has a 6 gauge cable going through the middle of it, you have an OBC.
@@golfcartking I have no part like that
I am hoping you can help me out and answer a question for me. My 2001 club car ds 48 volt golf cart is quickly losing power going up hills. The batteries are only a year old and charge to 51 volts and discharge to 47.8 going up the hills so I don't think it's a battery issue. All battery cables are new. Could you recommend what the problem might be? Maybe the controller or something? It runs absolutely fine on flat surfaces, just struggling up hills. Thanks
Unfortunately you have a battery issue. The batteries should never drop below 48 volts. Then they are being put under a load, it seems that they are not holding up.
I have mine already bypassed and my charger keeps turning off after 15 or 20 minutes removed the main positive cable and put the charger wire back on and my will keep working what is wrong with it
What type of charger are you using?
Im upgrading all my cables to 2g. Do I need to also upgrade wire from receptacle to batt negative?
No, that one can stay the 10 gauge.
What if your cart has 4 12 volts - would it be batt neg 4 ?
Yes
It's the motor most likely. Just fixed one just like that.
Do you have a video for the 48v club car ds
Unfortunately not.
How increase speed for motor
It melted the lead terminal post pretty good
How about the DL model
how come every battery I see in golf carts is deep cycle acid and not agm deep cycle
My guess is because of cost. I looked in to it and they were double the price.
I use marathon 200ah gel battery
Either my charger is bad or this idea doesn't work.
I have a 2014 precedent and OBC is not where u say it is on the 2011 ur working on. where is it on a 2014. This is an excel not IQ. It charges for 4 hours n shuts off.I check voltage on batterys and its right at 48volt but when you take off it drops below 48 volt and orange light comes on. batterys are original from 2014 when cart was bought. Ive check the voltage while it is charging an it has shown over 60 volts while its charging.
Sounds like you have a bad battery. Your 2014, does it have a PD Charger? Or ERIC?
Great ... how about a 2004 model
Thomas Abernathy All OBC by-passes should be performed the same way.
DIY Golf Cart So on a 2007 that has 4 12v batteries does it matter which negative post you go to?
Mark Mitchell Yes, you have to go to the last battery in the pack.
Mark Mitchell I just hooked to a negative terminal and it worked. Thank you...saved me some $$$$.
I was told by someone that the charger would not turn itself off with an OBC bypass, but my charger did turn itself off when the batteries were charged. However it is almost like it charges at full amperage the whole time.....the needle never drops below full blast.
Ergo 48 volt at full speed the cart stops abruptly
Mine stops abruptly at slow speed or any speed how to fix it
battery cabel to controler gets hot
Weak battery
Somebody have idea what s wrong
My golf cart wont charge
Either bad OBC or charger. Our newest chargers will work on either model.
Can you please reply me
Public comment?
Joe Baxley do I need to do anything to the six pin connector for an obc bypass?Or any other wires ? I read there might be a problem with controller lock-out
I have a 2008 CC - 48V - 4battery setup. The cart will not take a charge nor run. Stock Cart and unmodified. From what I can read the OBC is likely bad. I did the simple bypass in the video above.....plugged charger back in and nothing happened. Still will not kick the OEM charger on and charge the batteries. I took the charger to a friends house and plugged it into his CC...works fine. Any thoughts?
Brannon Helms if you cart is completely dead the Charger will not come on as it does not know it is plugged into anything the minimum voltage for the obc to come on is 38 volts I believe if you have the 4 12 volt batteries you can individually charge each one then charge your cart
Or you can take another 48 volt cart pull it beside the one that needs charged and with jumper cables connect both battery pack together main + to main + and main - to main - the charger will now see the voltage of the charged cart and come on after the charger starts carefully disconnected the jumper cables
Put to tow, get a charger with 40 amp startup and charge 2 batteries at a time on 12v setting for about 45 min. So 45min for2, 45 min for 2, 45 min for 2. Then charger will find them.
i have a 2005 precedent it accellerates very good but when you let off the pedal it quickly comes to complete stop any ideas?
Is this something that has just started or is the Regenitive Braking kicking in?
