Starter motor

[Ranga]

Whilst I know how to give a starter motor a tap to get it working again, I'm not sure as to why, and if this means it needs replacing. Had to give mine a tap this arvo after the Defender wouldn't start.

What's the go?

Could be a sticking solenoid. A good clean and lubricate usually fixes.

Could be the brushes.

I used a hammer to get my mini moke going on many an occasion.

This is instructive:
