| Ok well I just fitted a brand new Generator and RR to my 916. The old Gen turned out to have burnt wires inside the case. So burnt in fact that the insulation had fallen apart exposing bare contuctor. When I installed the new unit I tested the unregulated voltage and I was only getting 95VAC @ 6000 rpm. I'm gonna try a different meter when I can get hold of one.
One odd thing I noticed when I was doing final checks. I measured the redulated voltage across the battery and at idle I got 14.2 volts but as I revved the engine the voltage dropped to 13.4 at 6k rpm. Now I have read that a dirty fuel filter will cause the pump to draw more current. Since the pump is working harder when I rev the engine I'm hoping its just a dirty filter. I have a new one but ran out of daylight today. Question: Is it usual for the voltage to drop when the engine is revved or should it rise/stay the same? |
