I have here a behavior which I do not understand very well. When the trike is running, the voltage indicator of the trike generally stays at 14 volts, where it sould be when the accumulator is charging. But sometimes it drops to 12 volts, even with rpm above 1500-2000 and with lights on. The charging is clearly disconnected because I see the voltage droping from 14 to around 12 volts relatively fast, in 10-15 seconds. It happends sometimes that the entire trip (mine are usually around 30minutes to 1 hour) the charge is off. Usually when that happends, I do not use the ligths, to prevent discharging it and letting me in the middle of the road.
Does this happends to you, or does the voltage stays at 14 volts when the engine is on, no matter what?
