Hello i recently got a 82 yamaha qt50j, it was handed down to me cause it had a wierd ignition problem of starting running decent for about 2-5 minutes then dying. I played with it taking apart just about everything.
Ive rebuilt the carb several times, new plug, new gel cell battery.
I pulled out my digital multimeter tested everything i could, the factory manual doesnt give to many spec's it just says to use a old skool yamaha made tester.
Now for my main question how many volts are you supposed to get out of the coil?i have a pick-up and get 900v to the spark plug. that is barely enough to get it to jump the minimum spark-plug gap. I tested the orange wire to coil from the rectifier i believe, which fluctuates a bit but still get 1.5v.
So does anyone have any idea's of things to check? i want to ride this puppy a little more than down hill for 45seconds :(
TIA!
