So I just checked the fuses. The number 9 read 5-6 volts. That fuse controls:

diagnostic term.6, hazard warning system, clock, front roof light (electronic radio, vanity mirror light, relay comfort circuitry term.86)

Then I checked 'C', right next to it. It read 11 volts. I'm assuming this should not be reading this high. It controls:

rear roof light, trunk light, rear door locking system, safety belt handover alarm, sear back arrester (central locking system, door lights, reading lamps, aut. antenna.)

So have I found the drain? Or should 'C' be reading 11 volts?


Now that I'm reading through the manuals on w124performance.com, 'C' is on Circuit 30 which is apparently always 'hot', as is number 9. But should it be 11 volts 'hot', or some lesser amount?
