Slow or No Crank Starter Motor Solved - Bad Ground Wire Test Warning

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

Whilst diagnosing a faulty starter, I noticed a lot of people only test ground current draw on the case of the starter motor, which showed no fault, as there was a fault from the ground wire on the starter to the case itself.
Fitted another new starter, cranked over fast and fired straight up. 👌

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 2 жыл бұрын

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. 😎👌

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.

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 2 жыл бұрын

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. 😉

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.
