Okay... first post
I have a B6001 which has the D650 engine. I've been trying to check if the charging system is working but having problems trying to understand exactly what is what (the circuit diagram doesn't match what I have).
There is some form of generator on the nose where the fan is. This has three wires coming out; brown, white, yellow. I also have a regulator/rectifier which has 5 wires (can't remember the colours but, ISTR, there are two reds, a white and a blue). The white wire was broken but I've reconnected it to permanent +12V. I have no charging light so I guess I have a dynamo.
Now the problem is the voltage at the battery, with the engine running seems to be too low :-( I'm seeing about 12.7 volts which would tend to suggest a very low charge. The feed from the rectifier (or it could be a regulator) coming out of the white wire shows about 0.3 to 0.4 Amps with engine running and no other electrical load. If I turn the headlights on I see 2.3Amps coming from the rectifier. BTW the battery is freshly charged.
Can anyone please advise what the heck I have here?
i.e. is this a dynamo?
What should be present on the 3 wires from the dynamo?
Do I have a rectifier or a regulator and how should it be wired?
Also, what sort or charging voltage should I have with a fully charged battery?
Sorry for so many questions but I've spent several hours on this so far with very little advancement
Thanks in advance for all advice.
