Slow or No Crank Starter Motor Solved - Bad Ground Earth Wire Test Warning - Don't Check The Casing

It shows that a slow crank the majority of times it’s in your wires anywhere between the battery and the cranking motor. There are solenoids relays and fuses that are all connected by visible wires, that need to be tested with your multimeter. Any faulty wire can cause a slow crank.

[@RickTheSpud]

Normally yeah, but in this case not anywhere, in the wire on the starter I tested in this video. I've shown where the fault is with the current draw readings I've got. Changed the starter for another 'new' one and it solved it. 😎👌

@@RickTheSpud i’ll be honest, I took a new starter out and put another new starter in but, I’m still having the same dilemma.

I am still cranking away at it so if you have any helpful advice it would be much helpful thanks👍👍

Correct. The negative/ground wire comes back to the solenoid which is grounded from the case, which is grounded to the engine, which is grounded to the chassis, which is connected to the negative on the battery, which completes the circuit.

@@RickTheSpud you think it is, its not, you have a battery cable that goes to the other large nut. when the solenoid is activated it drops a flat plat in side to connect the battery wire to the main nut going to the motor. if its a grounding wire then the case would be positive , think about it, there is only 1 wire going into the main motor and its ground? and the case is ground? then where is the motor getting power to spin.

[@perez-gaara]

Did you at (1:52) connect probe to terminal post or the wire connected to the terminal. mine goes to 10.2v or i think it was 1.2v like what you shown. New battery and new starter cranks slow & only cranks with fuel pump fuse out, if i put it back it just clicks

[@RickTheSpud]

On the post. Sounds like you've got a different issue, maybe fuel pump related. 🙄

[@treytuckfield4219]

If you think that’s a ground wire make another video with the new starter in the car and run the same test. I’m betting that wire on the new starter will now have around 9-10 volts on it when cranking. The reason your car was starting slow was because there was only 7 volts on that wire when instead it should have been equal to battery voltage. Yes, replacing the starter fixed the issue but it was because there was a voltage drop in the + side, not the - side of the starter.

[@RickTheSpud]

It can't be a Live wire can it otherwise the whole engine block and chassis would be Live when cranking?

[@treytuckfield4219]

@@RickTheSpud there’s a rubber grommet that the wire runs through so it doesn’t contact the case of the starter. Also, why would they shield that wire with 2 layers of wire loom if it was a ground. No need to protect a ground wire. But since it’s a live wire they are required to shield it for safety purposes.

[@RickTheSpud]

But the big Live wire that comes from the battery goes to the other side of the solenoid?

[@abimariavargas7086]

Ground cable from the solenoid to the starter motor case, which is where the fault was. The positive cable feed comes from elsewhere, alternator I think?

[@nolovelost3981]

I have this slow crank issue after driving for a bit as if the battery hasnt been charged properly. However if it sits for an hour or even overnight it cranks fast with no issue as if the strater gets hot and becomes weak and cools down which than results in it cranking with no issue. Just a theory of mine. Anyway Ive tested the alternator its reading great and charging properly and tested the battery and its also fine. Could it be what you demonstrated here?

[@RickTheSpud]

Yeah could be. Try what I did in this video when the starter is cold and hot, and if you get low voltage readings at least you know it's not a current draw issue. Sounds like a tired starter when hot. Makes sense. 😉

[@AlexS-jo1bz]

Same issue here although when my car doesnt start, i am able to jump start it, which makes me believe its not the starter.

[@RickTheSpud]

Maybe, or by jump starting it you might be bypassing the earth fault. Try swapping the battery out.

I just had the same issue with slow crank and sometimes no crank at all. My battery wire to the starter was getting hot and when I opened the insulation it was burning. I changed the wire and problem solved.

If you want to teach others how to 'troubleshoot' a car. At least make sure you fully understand the component you working on.

This is totally wrong. If you wanna test ground then test from the engine or gearbox/trans to the battery - terminal. If there’s voltage there then there’s a bad ground. Quick bypass test is to put a jumper cable from engine block or gearbox/trans to the battery - terminal.
