Today I did some small trips around town and went to the village nearby to our son's home, to pick up a small trailer.
Parked in the middle of the (small) road to pull the trailer from his driveway, hooked it on and wanted to start. Soft click- no crank!
Tried again, no click, no crank. First car coming up to wait for me clearing the road.
What to do? Opened UB fusebox, blown fuse 40 (starter, EAS).
I know, don't just replace a blown fuse without knowing the cause but a second car waiting already.
Replaced fuse, blew again when turning the key in pos 3.
Maybe a short in the starting circuit? Pulled the small wire from the startermotor, replaced fuse again and it didn't melt when key in pos.3. Presto!
Unhooked trailer and pushed the RR up the drive, drivers in waiting cars looking annoyed. He guys, I need a hand!
Jacked it up and unbolted the starter (with limited tools, 8mm allanbit at home) and went to the electroshop in my town at 16:00 hrs.
The starter appeared to have a short inside, the guy opened it, the brushes were about 80% worn but still in place. All was covered under a thick black layer of greasy smudge that can have caused the short.
Luckily he had a new one on the shelf, original Bosch and I could have it for €160.- on exchange basis.
We went back, bolted it in and starts again! Can be imagination but it looks like she spins faster.
Came home, too late to do the job with the trailer. "Hi honey, that is quick, did you finish the trailerjob?"
"No love, I just lost 160 euro's"
