Have you just linked my post to itself, mate?
I have checked the generator coil resistance and it was 6 Ohm, far from 0.6 the manual quotes. This is on all three coils. How can this be?
The voltage was fluctuating at about 12.5 V when idling, going to 13.2 at 6K rpm. This is no headlights.
When I turn low beam on, the voltage drops to 11.75 V and going down. At about 11.5 the red battery light shows up on the dash. f***.
I have checked the regulator and is seems all good, no short circuits on inputs and 623 Ohm and OFL on output, depending on direction I measured.
I even checked the current it can give - a whopping 16.6 A when shorted onto my multimeter.
I fiddled around for more and noticed there are two more wires coming out of the ACG, I think this is pulsar coil?
After some cable probing and more advanced curses I measured the ACG coils again and it was 0.8 Ohm! How can this be? I was not dreaming.
Then right off I started the scoota and it was charging fine, with 13V idle and 14V at higher revs, even with the high beam on.
Happy, I assembled the scooter but next day's trip to work proved the nature of my fix to be sorely transitional.
It was back into same game, showing me the red battery light as a warning to turn off the headlight. Damnation.
Could this be a relay issue?
How can a coil change its resistance so suddenly?
Is is a static coil or rotating coil system in Downtown? Any more ACG design peculiarities inside?
