Starter motor/electrics?

[ScienceBoy]

Hi there.
Did you ever solve? Our starter has just stopped. Happen a couple of time before but then worked after a rest/cool down. All times were after a longest drive.

Hear relay click in glove box. Solenoid clicking too. No movement in starter.

And starter was replaced last year. With all the other issues experienced from this “VW Specialist” in the New Forest I wouldn’t be surprised if it’s a fitting/connection issue.

Solenoid is engaging
So let’s follow it through...

Continuity in trigger ok. Obviously because of above
Continuity to alternator ok
Starter body is earthed. Continuity checked ok.

But solenoid output nut connecting solenoid to motor via braid is continuous with starter body. Is that correct?
Would suggest that output from solenoid runs directly to earth. I guess that’s ok because I just tested a little electric motor I had.

The solenoid is earthed via the starter motor brushes while it is pulling in, so it slowly turns the motor while engaging. The Most common problem is high resistance in the brushes not allowing the solenoid to pull in. Adding a starter relay often adds more punch to push past the resistance.
