strange problem

[david lewis]

i have a strange problem inasmuch as my starter motor will start operating while i am driving along and i have to stop and turn off the ignition and restart then its ok for a while then does it again. the starter is new so i am wondering if it could be a faulty ignition/starter switch.

any one got any ideas?

cheers

Does sound like the ignition switch or wiring or the starter solenoid. First check the connections around the ignition switch and the starter solenoid.

What sort of starter ,, normal bendix or hi torque ?

 

does it actually power up or is the pinion trying to drop into mesh and rattling and clattering on the fly wheel teeth ?

[david lewis]

the starter is actually going into mesh,its a normal bendix starter

That's a different & interesting situation !! Thinking about it logically it could be either the solenoid or the ignition switch.

 

For sake of simplicity and ease of work it will be worth swapping the solenoid first. If the situation continues then I think it is reasonable to say the ignition switch is the culprit.

 

Whichever one it is, it will be a replacement exercise.

 

Good luck.

but is it under battery power        or engaging when accel /decel 

 

if it is being powered when the engine is running its easy to explode the motor due to the silly speeds its being thrashed up to.

a thought ...

its  not uncommon for the bendix spring to fail and car motion gets it to engage the bendix  if it was being driven by battery volts i would expect a right gnashing of teeth   as the two fight each other

thanks for your thoughts guys,i think i will start by checking the wiring then the ignition switch.

My starter motor did this occasionally, turned out to be the ignition switch. Not electrical but mechanically sticking in fire up mode. WD40 sorted it.
