Good Job, but you might also want to replace that battery cable which had obvious corrosion showing; that green stuff just keeps on creeping. Thanks for the video Sir!
My car is currently sitting right now and I just replaces the starter. New battery, all lights work, radio, etc. Could the ground to chassis still be an issue to a no crank, no start issue?

I've had problems with starting my 2010 Toyota Corolla LE. Try to start the car, hear a sputtering sound, weak lights on the dash. I get out, disconnect the battery clamps, then reconnect them then boom, car starts up with bright lights on the dash. Bad ground connection builds resistance that jams juice trying to flow through many possible electrical hookups. Beautiful video is a sight giver.
@@camillatucker9802 I haven't fixed my problem. Did you try what was shown in the video? Disconnect the ground wires to the chassis of the car, then reconnect them after cleaning them?
I would advise using a volt drop check rather than resistance. From the earth bolt to the earth eyelet a good reading would be 0v. Also, with the starter in place if connected a jump cable from the starter body to the negative terminal on the battery and it starts, you know you havean earth issue
Yep bad grounds can drive u nuts. Lights flicker is a good sign. Clean your cables and what I do even on the battery post clean and put a little grease on them. And same on the motor. Where the other end goes .
I always stand in front of the car, shake my fist at it, and yell, I AM THE BOSS HERE, CAR! This does not actually work, though. What about draining the gunk out of the Oil Pan, then looking at the crank shaft bearings? Cause, those crank bearings are likely to be stuck.
Grind all paint and the contacts ,,replace hardware with stainless , coat contacts with copper based dielectric grease .now treat all grounds on vehicle same procedure
I have issues starting my car when it's hot. Sometimes it just starts right away even while warm, sometimes has issues starting while cold, but mostly while warm (it sounds like a slow cranking) which is a pain in the ass as I gotta wait for it to cold down (around 45 minutes). I already cleaned injectors, replaced fuel filter and serviced the starter motor, all of that is good now, but still have the same issue. Gotta try this chassis ground thing now, hope I can find where the ground connections for everything is 😅
@@tongxiong3060 it did. I replaced some ground wires and problem fixed. I felt really stupid afterwards because the fix was kinda easy compared to everything else I did before 😅 But now I know that ground wires can "get bad" and need replacement.
@@cotelo that's good to hear because I'm having the no start issue as well and seems to not start when warm and more so when it's colder. I'll have to give that a shot. Did you have a no crank issue though? I just get a single click with all accessory lights on. With these issues I've been able to tap on the starter to get the car going but now it's just not doing anything. I replaced the starter and same thing so I'm kind of lost.
I like the scrapping off paint to get bare metal to metal contact but isn’t that going to create the same problem you’re trying to fix with the corroded ground bolts? Wouldn’t replacing with new ground bolt be the better solution? The thread to thread contact should be enough for the ground path.
It made sense to me at the time but I think you have a valid point. I still have the car three years later and thankfully the problem has not recurred.
Thank for this video, Now I suspect ground issues with new sound system producing noise, also my starter wire just cut itself in two. Many car have ground issues, my last car litteraly eat the ground wire.
Just prior too 4:18 I was feeling dumb and everything was over my head for sure, .... till I noticed you have a flux capacitor and 2100 giggawatts, I noticed that doc.
I had a same issue on my Toyota Yaris 2012 I lost the accessories current and It was a nightmare to find the grounding issue ...bad diagnosis results of spending money for no things ...I lost around 600 Euro for nothing....till we found the real issue...man I wish have seen this video before :( ....thanks anyway.
Hoping this is what's wrong with my 02 ford explorer, replaced the starter yesterday no dice, security light isn't flashing so no security issue, this is the only thing left that I can think of... Fingers crossed

Hey Percy! I know this post was like from 2 yrs ago. But I been having the same exact issues u described in ur comment, with my Infiniti. And I was curious if u ever fixed ur problem with ur vehicle and what needed to be done to fix it? Thank u
Glad to know all major ground. Just want to know more where can I find ECU ground ? Btw good video. Thank in advance. Wait I want to know ignition coil secondary ground too. I know where fuel injector ground are. It on engine easy to find.
Hi my name is Jorge I have a couple of questions to ask your guys I have a 2006 Toyota corolla having issues Lights blinking down how many ground the car have on the motor and transmission
Hey, question.. How did you have the starter wired up at 0:32? Just positive end or just negative end? Occasionally my starter plunger will come out with a single click and not spin, just like at 0:32. This rarely happens but is always fixed when I hook the starter up directly to the battery.. then it starts right up. I've had the starter bench tested and tried a different starter but get the same result. Ive checked all wiring and cleaned all connections multiple times, all seams fine..have you ever heard of this happening? Any ideas?
I had both positive and negative wired up with the positive directly to the battery plus and a jumper cable on the negative. That's a toughie. i would definitely use a meter (set to measure resistance-ohms). Check resistance from battery negative to various solid metal points on the engine and chassis. If you get anything but very low readings on the order a few ohms or less you still have a bad ground. It sure sounds like a poor ground connection since it starts directly from the battery.
The methods are good but the diagnosis is bad. You start with the simplest solutions first that involve NOT dismantling the entire interior. Then you travel ahead through the symptoms until you get to the more complicated troubleshooting that involves removing the starter, parts of the interior, half the dashboard, etc. If you're running a shop with high labor by the hour rates though I'm sure this is a method of choice to make tons of $$$$$$$$. First thing first would be making sure terminal posts are clean and tight and check it. Then source a new battery and check again. Many people are too ignorant to know their battery is dead. COPART yard monkeys even does this. They will say a car doesn't run/drive when it just has a dead battery. If that doesn't fix it then start poking around with fuses, wiring, etc, all that stuff.
My '10 Corolla LE has a slow cranking issue and never starts. Had not driven the car in about six days. Decided to start the car but would crank but not start. The tow company thought my battery was bad and possibly the alternator. So, I went and replaced the 2.5-year-old battery with a new one thinking a good battery might solve the cranking/start issue. It did not solve the issue. When I was installing the new battery I did notice that the ground bolt was very rusted. Do you think this is the issue? I have never had starting problems with the car before..
@ginalMechanic The car is at my mechanic and advised to him to look at the grounds and check to see if they are good. Hopefully, that's the problem and nothing major. also, during those six days the car was not started, the key fob battery was dead so I replaced that battery. After changing the battery. the key fob seems to unlock and lock the car. However, does the key fob have to be re-programmed for the car? Maybe it might be causing some issues with the start? Just trying to rule things out.
brilliant sir. but in my case, car starts ok but needs longer cranks mostly when warmed up. scenario:- 1) morning cold start, or whenever climate is cold = one crank ("hek") starts right up 2) after shutting engine off and restarted within 5 minutes = one crank ("hek") starts right up 3) after shutting engine off and restarted ANY DURATION AFTER 5 minutes, = 1st crank ("hek hek hek hek hek hek"), 2nd crank ("hek hek hek") then starts. I don't think the starter or ground is the issue here because of no.(2). Two different workshops mechanics told me it could be the distributor (w/out detailed checking). Battery/alternator both are fine. Been having this problem for four years now. on a side note (not sure if this is related) my car runs fine but idling is very slightly rough. Do you have any video on this that I could refer to? many thanks in advance.
This doesn't sound electrical at all. Since it occurs when the engine warms up I would wonder about the engine itself. I once had a car that would always start great but when hot it would randomly die and not want to start again. It was a broken head bolt. This could be a lot of things, many of them hard to find. I would have the compression checked first and see if that turns up anything.
@@TheOriginalMechanic my car would not die randomly, in fact never before been in that situation. ok sir will do that during my next service. thanks anyway for responding to my looong query sir 😅 have a nice day
No mention of how you set up he multimeter. Negative battery terminal removed but not positive? And, was the negative on the multimeter somewhere in particular?
I had the meter in the ohms (resistance) mode. I thought I pointed that out. Since we are dealing with a ground issue I did not disconnect battery plus. The meter measured resistance between the battery ground connection and the chassis t near the suspect lug connection. I hope this helps. I strive to be clear but occasionally fall short.
@@TheOriginalMechanic Thanks for the reply! Great video of course, you went ALL OUT. Still though where is the negative on the multi-meter placed? I just watched another video where buddy left the battery completely connected but place the multi-meter's '-' in the negative terminal..?
@@davidthomas6949 When measuring resistance the polarity of the meter probes isn't important. But to answer your question, I had the the negative on the clamp end of the battery ground cable and the positive on the lug bolting that cable to the chassis. A good connection would have been .2 ohms or less. I got 52 ohms which revealed a poor ground connection.
gezzz.... good way for the manufacturer to hide parts in the strangest places for us huh.... a stinkin relay hidden like that drives me nuts... The grounding system baffles me too... no thought put into it... maybe that's what they want.... they want ya to have to bring the car back to the dealer at some point to adress stuff like that. I can see someone junking a car because they couldn't find a "Electrical Issue" on a car when it was just a ground all along.
What do I do if the car cranks but won't start? The lights works but not the stereo. I changed to a new battery to but it's not working. Will this fix my problem?
Possibly. A quick way to find out is to check resistance between the battery negative and the engine block. It needs to be a few ohms or less. If not clean up the ground connections.
Good day. Before you repair that. Does the car crank when you started it? Because my car sometimes have that problem. Sometimes it doesn't start nor crank. Thanks will wait for your answer before i subscribe and share your videos. Thanks
The car never cranked until the ground was repaired. If your car cranks the problem is likely to elsewhere. A meter comes in handy here to determine if power and ground circuits are proper.
That means i need to find where is that knots to clean up. May it is also dirty. So that i will not pay high price in the shop. Because they do not know why my car sometime do not crank and start
Awesome video. I think I have the same problem only the washer area on the pluss+ pole is messy(corroded, filthy) It starts though, but it can sporadically stop, also sporadically not start. But the pluss pole is not ground. I also see that the negative pole doesn't have it's electronic box on top of it. It's gone.
Thanks man. The battery is at 95% efficieny. Cleaned the nuts and bolts area. It was really diry/corroded. Put some battery pole grease on everything(assume this is dielectric grease) Need to find the grounding point under the car. Saw the red one. Gonna clean that as well. It's puzzling why these don't have a weather shield of some kind. Maybe electrical tape isn't such a bad idea.
@@TheOriginalMechanic Ok. I have a problem with a Grand Vitara. When I switch the starter, the car doesn't start and the dash lights start flickering erratically. It also makes weird noises inside the dash, specifically around the radio and AC controls. What can it be?
Great tutorial, but I wouldn't suggest connecting the black cable to the negative (-) terminal on your dead battery. If the battery is leaking hydrogen gas, it could result in an explosion.
@@AyixliaEither the ignition switch or the switch built into the starter. I have never actually seen or heard of either of these causing your problem though. That's a weird problem.
@@TheOriginalMechanic My starter is new so it may be my ignition clyinder swtich or it may be a positive cable grounded so where or a weak, worn cable?
@@Ayixlia A grounded positive cable would blow a fuse. You might want to swap out the starter relay (often nearby relays are identical so just switch them). Also make sure your B+ cable and S cable on the starter are not crossing (touching) somewhere.
My 2018 Promaster City Van won't start unless I chassis ground my battery. Battery shows 12.8v. Nothing turns on and has actually locked on to my key and won't let go. I am then able to drive it until remove the key, at which time displays Hill Stop Warning and incorrectly that I am low on Gasoline. I too suspect a bad Chassis ground somewhere

This doesn't sound electrical at all. Since it occurs when the engine warms up I would wonder about the engine itself. I once had a car that would always start great but when hot it would randomly die and not want to start again. It was a broken head bolt. This could be a lot of things, many of them hard to find. I would have the compression checked first and see if that turns up anything.
@@TheOriginalMechanic my car would not die randomly, in fact never before been in that situation. ok sir will do that during my next service. thanks anyway for responding to my looong query sir 😅 have a nice day
Is that with the key on in the on pos when testing for resistance
No, power doesn't need to be on for resistance checks.
Thanks for your share! God bless!
Outstanding!
after cleaning the grounds use copper neverseize .
No mention of how you set up he multimeter. Negative battery terminal removed but not positive? And, was the negative on the multimeter somewhere in particular?
Also next time I suggest adding some dielectric grease to the fttings to ensure continuity in the harshest conditions.
I had the meter in the ohms (resistance) mode. I thought I pointed that out. Since we are dealing with a ground issue I did not disconnect battery plus. The meter measured resistance between the battery ground connection and the chassis t near the suspect lug connection. I hope this helps. I strive to be clear but occasionally fall short.
@@TheOriginalMechanic Thanks for the reply! Great video of course, you went ALL OUT. Still though where is the negative on the multi-meter placed? I just watched another video where buddy left the battery completely connected but place the multi-meter's '-' in the negative terminal..?
@@davidthomas6949 When measuring resistance the polarity of the meter probes isn't important. But to answer your question, I had the the negative on the clamp end of the battery ground cable and the positive on the lug bolting that cable to the chassis. A good connection would have been .2 ohms or less. I got 52 ohms which revealed a poor ground connection.
My car is full of rust and all I here when I try to start it is a click coming from the starter 😢
That click is likely the solenoid and a sign that there is either not enough power from the battery to the starter windings or open windings.
@@TheOriginalMechanicwhat are windings?
@@j7sportvideo24 The electrical part of the starter. I'm basically saying that the starter itself may be bad.
For the ground did you have to disconnect the battery first or just remove ground ?
The ground strap being removed is about the same as disconnecting the battery.
can any nut & bolt be used? or is it only stainless steel?
I would suggest using automotive-grade fasteners
gezzz.... good way for the manufacturer to hide parts in the strangest places for us huh.... a stinkin relay hidden like that drives me nuts...
The grounding system baffles me too... no thought put into it... maybe that's what they want.... they want ya to have to bring the car back to the dealer at some point to adress stuff like that. I can see someone junking a car because they couldn't find a "Electrical Issue" on a car when it was just a ground all along.
I found that disappointing too. Thanks for watching and commenting!
What do I do if the car cranks but won't start? The lights works but not the stereo. I changed to a new battery to but it's not working. Will this fix my problem?
Possibly. A quick way to find out is to check resistance between the battery negative and the engine block. It needs to be a few ohms or less. If not clean up the ground connections.
@@TheOriginalMechanic I try it out. Thanks for the tip!
Good job.
great video
is car batteries negative sides considered ground?
Yes.
Thank you
Good day. Before you repair that. Does the car crank when you started it? Because my car sometimes have that problem. Sometimes it doesn't start nor crank. Thanks will wait for your answer before i subscribe and share your videos. Thanks
The car never cranked until the ground was repaired. If your car cranks the problem is likely to elsewhere. A meter comes in handy here to determine if power and ground circuits are proper.
That means i need to find where is that knots to clean up. May it is also dirty. So that i will not pay high price in the shop. Because they do not know why my car sometime do not crank and start
Mybcar sometimes do not start nor crank in the morning, but if it started, all day there will be no problem. Do you think i need to clean that knots??
Do this work for 2006 Nissan Altima as well buddy
Any vehicle can develop this problem.
you amazing thank you so much
Awesome video. I think I have the same problem only the washer area on the pluss+ pole is messy(corroded, filthy) It starts though, but it can sporadically stop, also sporadically not start.
But the pluss pole is not ground. I also see that the negative pole doesn't have it's electronic box on top of it. It's gone.
Make sure that battery terminals are clean and corrosion free. That's a good place to start. Also, corrosion can be a sign of an aging battery.
Thanks man. The battery is at 95% efficieny. Cleaned the nuts and bolts area. It was really diry/corroded. Put some battery pole grease on everything(assume this is dielectric grease) Need to find the grounding point under the car. Saw the red one. Gonna clean that as well. It's puzzling why these don't have a weather shield of some kind. Maybe electrical tape isn't such a bad idea.
Is it necessary to dismantle the dash?
No it isn't.
@@TheOriginalMechanic Ok. I have a problem with a Grand Vitara. When I switch the starter, the car doesn't start and the dash lights start flickering erratically. It also makes weird noises inside the dash, specifically around the radio and AC controls. What can it be?
@@leumamk5259 I would start looking for a bad ground. These are the types of symptoms that show up when there is a poor ground.
why don't you jus replace the bolt instead of the unnecessary paint-removal which is there to keep the body from rusting under the lug
If i have a bad ground connection an call a mobile mechanic come out how much should I expect to pay for him to fix it
Way too much! You'll get a new battery & starter & who knows what else he will throw in. Just fix the ground yourself. I am a woman & I can do it.
Do I disconnect my battery 1st?
You need it connected to test it and disconnected for the repair.
Brilliant
Great tutorial, but I wouldn't suggest connecting the black cable to the negative (-) terminal on your dead battery. If the battery is leaking hydrogen gas, it could result in an explosion.
Now to get a new fan belt.
Can this cause your starter to keep turning over?
No, that sounds like a bad switch or relay.
@@TheOriginalMechanic Starter rely or what switch?
@@AyixliaEither the ignition switch or the switch built into the starter. I have never actually seen or heard of either of these causing your problem though. That's a weird problem.
@@TheOriginalMechanic My starter is new so it may be my ignition clyinder swtich or it may be a positive cable grounded so where or a weak, worn cable?
@@Ayixlia A grounded positive cable would blow a fuse. You might want to swap out the starter relay (often nearby relays are identical so just switch them). Also make sure your B+ cable and S cable on the starter are not crossing (touching) somewhere.
Hey i wonna no i got a gbodyvan it doing the same thang as ur 🚗 would it be the same
Not the same.
My 2018 Promaster City Van won't start unless I chassis ground my battery. Battery shows 12.8v. Nothing turns on and has actually locked on to my key and won't let go. I am then able to drive it until remove the key, at which time displays Hill Stop Warning and incorrectly that I am low on Gasoline. I too suspect a bad Chassis ground somewhere
Where you @ bro 😂
🤔👌🕵incredible🤗👍😁
Nice
Ok good start
sweet
Лайк! Молорик и привет из России:)
Lol spends an hour scraping paint off with a knife then gets out a dremel
wow
great video
