How do you test a starter solenoid on a Harley Davidson?

Move the voltmeter’s red probe to the solenoid’s power input terminal, located on the top of the starter solenoid. Turn the ignition switch on and shift the motorcycle into neutral.

How do you fix a starter that won’t engage?

Will hitting a starter make it work?

Tapping on the starter usually doesn’t make the starter work if the solenoid is bad (think Nippondenso). OTOH, a starter with a bad armature segment responds well to tapping or banging with a hammer.

Why does tapping on a starter make it work?

This works because the brushes wear out which results in an inadequate electrical contact. By gently tapping on the back of the starter with the hammer, the brushes are knocked back into place so they can make contact one more time.

How do you free a sticking starter motor?
