Mi16 Still Not Starting - Not The Usual

[Powers 13]

My symptoms:

 

Starter motor only turns the engine in a sort of rur-rur-duh. Where it should be rur-rur-rur then the engine fires. The duh is a sort of hesitance as if something is stopping the engine from turning - but it is not in gear!

After a couple of times trying to start i notice that the earth on the gearbox is getting warm!

 

I have changed the starter motor, however this has had no effect.

 

Any ideas?

Cheers.

My Mi has a lazy starter noise.

 

Loads of cold weather about, so is you battery man enough? Most common cause of none starting.

 

Make sure cambelt has not snapped! As I hear starting puts a lot of strain on it and it could have gone while attempting to start.

Cambelt defo not snapped and i even tried jump leads. So must be something else.

sounds like the starter is starting to die, because its tuning slowly its pulling a lot of power for the work its doing and hence the warm wires. Stick a derv starter in it out a 306 and it should fire no problem.

From what you are saying I'm assuming that it is the connection to the box that is getting warm. I'd take it off and give everything there a good clean and see what happens.

 

The warm wires are an indication of a poor connection. Starters draw HUGE currents and even a very small amount of resistance on a connection can cause problems. Power disappated (heat) = current * current * resistance so large currents = Very large power dissapated for even a tiny resistance.

P.S. a stalled starter will draw even more current than normal, not helping matters!

I will try cleaning the connectors and let you know. However the starter motor is a brand new Value unit for a diesel, so i doubt it is that.

If that doesnt work check your ignition amplifier, sounds similar to a problem i had after an mi16 engine swap, engine turn over very slowly and hesitated sometimes, new ignition amp sussed the problem.

Sounds exactly like the problem I'm having at the moment I've even tried charging the battery up (brand new). It starts a peach first time, appears to be charging up (14+ Volts at terminals) and runs fine. Stop the car, try to restart and there isn't enough oomph to turn the engine over fast enough.

 

I've cleaned up all the connections and fed in some more earth cables.

 

I suspect the battery isn't man enough, if yours is getting on a bit, I'd look at changing it. Also, I'd suggest getting the diesel battery as well seeing as you're running a derv starter motor

[Rob_the_Sparky 9]

Diesels need big batteries due to 24 to 1 compression...

Still no luck on this matter. I even tried with a redtop 20! Next will be a redtop 40 (battery)!

Try starting her with some petrol straight to the pump from a bottle. If only to eliminated fuel blockage.

 

Just a thought
