Starter trouble (engine turn too slow)

[ElanDream]

Hello, I have trouble probably with my starter engine.
First one is dead then I replace by a new one.
I'm totally satisfy but not for longtime (few start maybe less than 5!)

After that the thing is:
not all the time but really often when I try to start the engine and the starter turn really slowly like if there is no battery. In this case I can not start engine.

I have check many time:

Battery level
Ignition timing
compression (Cold 13 bar around 188psi for all cylinder)

I know there is two different couple of starter and flywheel I have check to and count the thooth number on both and it's fine.
I try with Hi-torque starter, but same with two different I'm not satisfy to because I have also another trouble
The tooth profile on flywheel is made inertia starter (not pre engaged).
I think to make flip but in this case they are turn in wrong way!

If some body already have this problem....please give me your help.

Hi,
From my experience, I would always recommend a high torque starter motor.
The manufacturers of my Powerlite said that their motor does not need a chamfer on the entry side of the starter ring teeth. The motor will manage quite well without.

Also check battery to chassis ground and engine to chassis ground. They need to be nearly
spotlessly clean.

Hi Eric thank you for the fed back about the chamfer because i am not at peace about that.

>Thank you Greg, I will try to do it again but for be sure I use really big cable (big diameter) from battery to engine housing (earth) unfortunatelly this is did not change anything

I will check the earth wiring and chage if i have any doubt.

It's not just the cable: make sure there is no corrosion on the chassis bolt nut and washers of the battery cable earth..and uts tight.

Also, check, clean and lubricate the solenoid connections and the live cable connection to the starter...

Ok Tony I will check everything

Agree with Giz

Engine to chassis earth !
Test it by using a jump lead clamped to the chassis and something metal on the engine, then try and crank engine… if it works it is the fixed lead from earth to chassis, if it makes no difference look for something else…

Unfortunately I have already try but I need to check again everything to be sure. Restart from zero to be sure

Before changing anything with the starter I would replace the solenoid. I had also slow starting troubles with my car and finally replaced the solenoid and all was solved immediately. It is an easy and cheap fix and is always the first things I would try.

A bad solenoid can indeed prevent your vehicle from starting properly. The solenoid is an important part of the starter system, acting as an electric switch that transmits electrical current from the battery to the starter motor. When you turn the ignition key, the solenoid is supposed to engage the starter motor and the car's ignition system. If the solenoid is faulty, it may not engage the starter motor correctly, leading to issues like no clicking sound, a series of rapid clicks, or the engine not turning over at all.

Yes for sure but now I have the problem with non engaged starter or inertia starter.
Then solenoid can not be the problem

Engine ground strap and solenoid checks would be my first places to look, too.

Did you say you had tried multiple starters, with the same result? Or did I misunderstand?
