- Опубліковано 5 жов 2024
- So, the battery on my 1996 Harley is dying. In this video I show you how to perform a Harley Davidson Evo Stator test and a Voltage Regulator test. When testing the Harley Davidson Evo Charging System you'll find that it is pretty easy to do! All you will need are the specs and a digital multimeter. What I found with doing these tests on my Evo Fat Boy wasn't at all what I expected. Check it out.

7:47 Whether it's a solid mount or rubber mount the connector at the engine is going to shake, in fact on a rubber it will shake a lot more. A good helping of dielectric grease in that connector will help the corrosion issue, that is most of the problem.
Fair point! I did use dielectric grease on the connection but maybe not as often as I should have. Still, that is a great tip. Thanks for pointing that out!
Excellent video short and sweet and right to the point.
Thanks! I'm glad you like it. Thanks for taking the time to watch.
Very informative and Spot On. We all love our Harley,
and need honest help along the way.
Thank You Very Much🏁😎
Thanks for taking the time to watch and to comment, I appreciate it! I Love this Harley and we've been through a lot. I am glad the video was helpful!
You're missing a hold down on rhe front of the engine. Helpful video, thanks
Thanks for the heads up! I am glad you liked the video, thanks for watching!
Bro your the best man you saved my ass today love your video always straight to the point and very informative I hope your having a fantastic Sunday Morning brother god bless and take care of yourself💪🏼🙏🏻👑👍🏻
Sweet!! I am glad it helped out! Thanks for watching and for your comment, I really appreciate it and thank you, same to you!
Nice simple video. Just been doing the same tests on my 98 Super Glide. Poor connection at the stator plug.
Thanks, I am glad you like it! Yeah, that connection drove me crazy!
Your video is well done.........I cant stand watching videos of peoples faces when trying to find out quick info
Thanks Steve! I really appreciate it!
Thanks for the video. I just bought a 88 Softail and it dies on me when it warms up. Then when I crank it it sounds like its going to fire at first but not. It is charging tho.. I did the same test off the battery like you did.. charging nicely. I did make sure its getting fuel (not the problem). I've replaced the dang CPS (crank positioning sensor) the coil, the ignition switch... hell I'm going to replace the voltage reg' like you did. My regulator looks like its the stock 34 year old original! And I pulled that 2 prong plug and it looks old. I hope this fixes it,, I'm runnun' outta' money!!!! Hope I get good results like you did!!!! I subbed to your channel, I'll let you know if the VR fixes this. Thanks again!
Hey Ohm! Tha js for watching subbing to the channel. I really hope swapping that out fixes the problem. Do you have a service manual and gone through the flow chart on what it could be? I know that can be frustrating so hopefully it works. Best of luck with it!
@@MOBStreet83 Man.. imma tell you. I'm a happy camper today bub,, I ended up finding that dang gone ignition module a couple hours ago. The dag gone wires going into it were charred like I always burn my steaks on a Holiday!!!! Boy I'll never figure out why the heck Harley mounted it RIGHT under the oil tank. It was a battle.... but I got her out and race ready to get me a new ICM. You can bet it's not going back under that tank. If I have to I'll lengthen the wires and install it in a better, more accessible.. safe spot. WHeeew... I'm beat brother,, but in a good way. This has been the problem with this beautiful Softail since I got it 2 weeks ago. Anybody ever looses spark on these classic EVO's check or test out your ICM before replacing all them dog gone parts like I did! Thanks MOBStreet 83 again for the video. You inspired me to git' out there and get er' done! Will keep you posted bud! Good numbers around the ponderosa, happy riding!!!!! 👍 😜
@@Ohm10-8 Convert it to points ignition and never worry about it. When points go bad, they let you know ahead of time and can be swapped out in minutes on the side of the road. A conversion kit is about $100.00 and will last you a life time with proper maintainance. Spare points and condensers are about $50.00
Good job. That helped me a lot. Very helpful for DIY guys.
Thanks! I am glad it helped. Thanks for taking the time to watch, I appreciate it!
Cool man. Just starting having issues with my evo.Gonna shoot a video on it as also.
Thanks! That's a good looking Softail you got there! I really dig the tank graphics. What issues are you having with it?
@@MOBStreet83 I’m getting the click click I don’t want to start! Had to get push started to get home. I have a funny feeling I’m having the same connection issue with the voltage regulator.
Thanks for the Video and taking the time to do it. I may be back with a few question. LOL
You bet! I hope it helps. If there are any questions let me know.
Mine kept popping off the 2 prong V.R.stator plug so I super.glued it , no more problems
😂 Simple fixes! That's Awesome!
not bad buddy...honest informative video...thumbs up !!!
Thank You!! I really appreciate it and I'm glad you liked it!
Awesome video
I'll try all you said.
Thanks
Best of luck!
Excellent! Thank for the help, man! Great video!
You bet!! I hope it helps. Thanks for watching!
Excellent video, thank you
You bet!! Thanks for watching and I hope it helps.
Great information! Keep it up!
Thanks William! I really appreciate it!
Nice video from Australia having sort of same dramas with 87 softail evo, have replaced battery and stator and the voltage regulator but is still not charging the battery, do you have any ideas on how to exactly wire voltage regulator on to circuit breaker ? I forgot which wires go where 😅
Hey! Thanks for tuning in! My circuit breaker sits right behind the oil bag on the right side of the bike. So, I have my voltage regulator bolted to the left side of the breaker and my positive cable on the right side of the breaker. I hope that helps!
Very great video got my knees back in the breeze
That is great to hear!! I am glad it helped!
Thanks for the Intel !
Quick question:😮the single wire coming from the regulator to the battery, does it hook up to the negative or positive side of the battery?
It is a ground strap and needs to be connected to ground which would be negative.
Thanks mate helped me out big time
You bet!! I am glad it helped. Thanks for taking the time to watch and to comment, I appreciate it!
Problems putting stator in and have a part I dont remember where it goes.
What part do you have leftover?
how can you test stator with bike running and you have the Voltage Regulator unplugged testing in the socket hole of the stator ??at time 4:05?
It will run off the battery until the battery is dead. That is what was throwing me off. Everything was testing fine but the prong on the Voltage Regulator plug was broken so the connector wasn't staying in place and the bike would run off the battery voltage until the battery died.
Nice garage setup bro!
Thanks, I appreciate it! Thanks for taking the time to watch!
Really need some help here. Been in all the forums getting conflicting replies.
83 FXSB 1340 brand new regulator putting out 14.58 fully revved. Is that gonna cook my agm battery? Guy's saying 14.4 should be the max. The old lead acid batteries can handle the higher voltage but the agm batteries will cook over 14.5? Thank you in advance
No, you should be fine. I was always taught anything g over 15 is gonna fry things. You should be good.
where did you get that cool flame seat? i would love to buy one for my 93
I bought it from Drag Specialties. I saw it while I was at the dealer show in Wisconsin and talked with them a while about it. I don't know if they have the flame stitched model any more but here is the link to the website and then type in you machine information. www.dragspecialties.com
@@MOBStreet83 thank you !
Question, same evo 2 prong plug...New battery,New Rectifer, getting strong voltage from the stator up to 50volts ac, but still not charging the bike...Tested my 30 amp breaker to where the rectifer goes has continuity, also have continuity from the breaker stud to the battery?..Any thoughts, Could be stator still be bad if its throwing out strong voltage
Is it not charging while the bike is running? Have you put the multimeter leads on the battery while running and see what your battery voltage is? Is should measure 13.5 to 14.8. Or is it dying after sitting over night?
I got same problem, I have just replaced voltage regulator… how it ended in your case?
I just bought my first bike it is a 2019 harley-davidson xl1200ns and my battery won't stay charged what should my stator be at still at 14? Or lower since it is a smaller bike?
Nope, it should still be around 14. Do you have any electrical aftermarket upgrades done to the bike? It could be a parasitic draw that is draining the battery.
@MOBStreet 83 the only thing I have added is a tracker but it said it was ment for a motorcycle but it had a tuner on it when I bought it other than that mechanically it is stock
Diaekectric grease on plug will help stop corroded connections
Good call! I did add some afterwards. I should've shown it!
damn,, for 20 plus years I have been doing this wrong,,I just fire the bike up and read the voltage to the batter.y......12 volts before engine starts and about 13 to 14.5 when its running..with the high beams on
.,,Am I wrong??
No, you aren't wrong! I just wanted to go by the book for the video to make sure I was giving correct information. That is how I would normally check as well just to make sure things were okay. This came about because those methods weren't giving me the info I needed this go around.
@@MOBStreet83 I can appreciate that!!!! Im still learning stuff even at 54 years old
@@USNVA-yn6cp I hope to be learning at that age as well. Thanks again!
Hello Mob Street ! I have a question about my 1998 Heritage , how do I get rid of that fart, hip cup, back fire like deal , back through the carb ? Do I need to advance my timing or retard it ? THANK YOU
Hey Tommy! I wouldn't do anything to it just yet. Have you done anything to the carb? Is it still the stock jetting? How's the air filter? Has it been cleaned? Do you have an intake leak in the carb boot? There are few things to check and need more info on before you go and start messing with the timing.
@@MOBStreet83 Thank for the reply ! I got this bike as the 2nd owner with only 474 miles, it has done it since the day I got it ! The manual says it is trying to advance the the timing , normal, and to run a high octane gas ! The bike runs good, but you can ride it all day and then it will fart and almost shut the engine down ! It's just aggravating !!! I recently put in a a new cps and wondered if I could advance it or retard it and maybe solve it . I did mark the original cps position timing marks. THANK YOU MOB !!!
Getting conflicting info. Other info says stator plug can have .02 ohms. Very confused as my 1998 flhtcui goes from l to .02 on both terminals from stator. Good or no good?
If you are checking for a grounded stator, check each terminal against a good ground. You should have no continuity. Across the two pins of the plug itself you can have 0.1-0.2 ohms if it is lower than that the plug is damaged and the stator should be replaced. That is straight out of my Factory Service Manual for the 1995 and 1996 Softail Models.
@@MOBStreet83 ty for that very clear explaination.
You bet! Thanks for taking the time to watch the video.
How can I actually test the rectifier and not assume it’s what’s wrong ? I have a good battery and a strong stator voltage but my bikes not charging, I’ve swapped regulators like this video suggests and still nothing.
It must be the connector after the rectifier the little single wire one, or I have a bad wire somewhere from that connector to the battery, or ground right ? I’m so tired of this bike man I’ve tried everything and have been let down everytime. It’s got a good battery, and a good stator, and I’ve swapped regulators. Almost to the point of giving up. I have no one or no shop that can help me as my bikes older than 2000 so the Harley place won’t touch it.
Hey Hunter! Don't get discouraged, I know it sucks sometimes trying to figure this stuff out. Here is what my service manual says about "testing" the regulator. It isn't hard to do. First off, that little single wire is your ground wire. So make sure the connection it screws to is nice and clean on the bike. Here is what my manual says:
Regulator Inspection: The regulator base must have a clean, tight connection for the proper grounding. Check by using ohmeter with one lead on a known good ground, such as a battery ground cable, and the other on the regulator base. Connector plug at engine crankcase must be clean and tight....(this is what was wrong with mine)
Regulator Bleed Test: be sure regulator is connected to the battery. Unplug regulator connector at engine crankcase. Use a trouble light and touch one probe to a known good ground and the other to the regulator pins one at a time. If the light glows, replace the regulator.
Let me know if this helps. Yeah, you can test the wiring from the battery to see if one is grounded. Use your ohmeter to check one end to the other to see if there is a break in the wires somewhere.
@@MOBStreet83 I was extremely frustrated yesterday when I left that comment, so I’m sorry if it came off like ahole. But I ended up finding that same information you sent right after I left that comment and continued to learn about how the system works and thought out what mine could be doing with the results from the test. Turns out the one wire connector that goes from the rectifier to the battery was no good, and I had some poor grounds. I buttoned it all up yesterday before dark and got to ride it home, and even rode it around this morning and still have a good 14 volts at the battery after riding. Thanks a lot man your video was helpful and helped me figure out what I needed to understand. I appreciate your help, I was just super frustrated yesterday but luckily I found your video which led me to diving deep into the internet to find some more tests and the basic functionality of the charging system on my bike. I hope you have a great weekend!!!!!
@Hunter Lancaster awesome!! I'm stoked you were able to find it. You didn't come across that way at all. I said that because I have been in your shoes I don't know how many times! I'm stoked you got it figured out. I hope you have a good time riding!
if i unplug stator bike will not run . any ideas ? its a 2003 tc88 softail i have no charge at battery
I don't know for sure....It could be a few things. I would check the battery first. If mine is dead the bike won't run at all, even if everything is plugged in and working well. The stator isn't enough to run the bike by itself.
@@MOBStreet83 thanks for reply my battery is at full charge and while running slowly drops voltage
@@hd-wr9fp Ever find a fix?
@@TWrecks Yes It Was Regulator >
I’m getting 0.48 on the rectifier test, both are equal. No issues to ground etc. is this ok or too low? Battery seems to be getting charged ok when i test at idle but it drains during a ride and will die and have cooked the battery after about 25 miles. Everything else seems fine apart from this test. How close to 0.5v does it have to be?
What reading are you showing at the battery during Rev? It shouldn't jump above 15 volts. It sounds like your voltage regulator is shot
@@MOBStreet83 14.7v. It doesnt really change with revs, if anything it drops to about 14 at high rpm
Hey, I’m heading over to Harbor Freight to grab a meter. What should it be able to read? Thanks in advance
You want to get a DVOM meter. One that can read ohms and one that can read the voltage. The test on this will be less than 20 volts. Even basic DVOM's will be perfect for this test.
@@MOBStreet83 yep. Voltage regulator. Amazon will have one at my door by Wednesday😂
Sweet!! Mine has taken forever but it's supposed to be here tomorrow. Turns out you can't just by the connector and splice it in.
This has to be confusing to your viewers when you say it should read 13.5-14 running and it does then you say well
Forget that it’s still the regulator ha
Yeah, it could be. The plug was broken and it would read correctly for a while until the vibration moved it loose. That's why I show the broken plug in the video.
@@MOBStreet83 ya
What?
what?
Hey buddy you almost have 1,000 subscribers I can make 200 UA-cam channels and subscribe them all to your channel, but it's going to cost you , I want a "T-shirt" at least LOL. Wife loves the Harley but I already sold her on getting the TDUB!
Man, that would take a really long time to do! But, I do appreciate the gesture! I am thinking of getting some shirts, but I am more of a button up shop shirt kinda guy so we'll have to see what we come up with! My wife really loves the TW as well, I don't think you made a bad choice at all!
@@MOBStreet83 No I didn't I have been riding my entire life mini bikes, dirt bikes, atv's, and road bikes. Not interested in speed anymore , the TDUB is the do everything bike. I did my home work been saving I just need to wait until one is available. I do enjoy your videos I will make some when I get the bike. It is hot as hell here anyway right now believe me you want to be on a boat, in water, or air conditioning. I do all three this time of year LOL.
Ha ha, that's awesome!! I wish I had a boat or was around water somewhere...it's been in the high 90's and 100's here the last few weeks!
Good stuff, thanks👍🏻👍🏻
No worries!! thanks for watching.
