Output Voltages in gt250
Posted: Sun Apr 14, 2019 1:07 pm
Hi all, been reading through this great forum and hope someone can help. Im just in the process of rebuilding my GT250B. Crank has been redone, new standard exhausts, and its got a replacement rectifier. ( https://www.discountbikespares.co.uk/pr ... 0-pattern/" onclick="window.open(this.href);return false;" onclick="window.open(this.href);return false; )
I bought the rectifier used, so dont know its specifications, or if its working right. My issue is, when I started the bike up, and put the lights on, the headlight bulb blew when I revved the engine. Checking voltages across the battery, Im getting about 13 volts at idle, rising to 13.8 volts at 5000 rpm. With the lights switched on, the voltage goes up to 15.8 volts. And that is without a bulb in now.
Do you agree thats too high and my rectifier assembly isnt working? Or could it be a simple connection problem?
I cant find any details regarding output, but do know it puts out more voltage with the lights on.
By the way, Im getting a serious misfire when its warmed up, and the points are sparking like crazy in the right side, indicating a bad condenser. Not related, im sure, but just another hurdle to getting it back on the road.
Any help or advice welcome.
