Ladies, Gents, suggestions please!

Diagnosed slight overvoltage (15.5 - 16.5 volts when riding, 14.4 volts in idle) and battery is discharging slowly while riding. Not really discharging, but seems not get charged, because it is losing power with every start. Borrowed a new battery at Oschersleben after the bike started clicking - just to make sure - and on my ride back (220 mls) noticed that this one behaved similar like mine.

Stator resitance is infinte to ground for all phases, phase-to-phase is 0.1 - 0.2 ohms, so wires seem okay, alternator delivers 20 volts per 1000 rpm, which sounds promising too. Didn't dare to check connector 77, as I know, that one is not forgiving, but do not have any suspicions that this one might be the culprit.

Now, how to proceed? Replace VR on spec? I'm definitely going for an aftermarket part then, still waiting for a response from the swiss forum, where some people did the same.

With ignition switched off, there's a current of only 40 mA flowing, which is probably keep-alive for the ECM and the instrument cluster.

I compared ECM output to a multimeter readout, these two show a voltage difference of 0.5 volts - so whom to believe? I also redid all ground connections I was able to reach, and the starter sounds more powerfull now, a part of the problem seems fixed now. But I still don't know, what's causing the overvoltage and why the battery isn't charged well.

Battery voltage is (all values are multimeter readouts):
- 12.3 volts with ignition off
- 12.1 volts with ignition on (headlight and tail light on, fuel pump off)
- 10.5 volts when cranking (ECM fuse pulled, no fuel pump, no injectors, no ignition)
- 14.0 - 14.5 volts when idleing

Normally if you read over voltage the caused will be the rectifier. Could you borrow a rectifier from another bike?
