Relays next to Starter Relay

[Assel]

Hey Steelsoldiers,

does anyone know what the 2 smaller black relays next to the starter relay are for? couldnt find anything on the web and I´m just curious.

Thanks

One is for the voltmeter. And I think they are for the charging system. They are both Bosch relays on my trucks. I never had one go bad. I had them missing but never had one go bad.

Voltmeter and GEN2 exciter circuit

The parts manuals TM 9-2320-289-20P and TM 9-2320-289-34P have the GM part numbers listed. Not sure how the European parts stores cross reference the part numbers.

I see he has an M1009, but for future searchers, on an M1010, they are for the voltmeter and spot & flood lamps.
