Having light problems on 1983 Yamaha YTM200E. The lights all work when using the ignition key switch, while not running. However, when running and using the handlebar switch the lights will not work. Using the repair manual from Clymer, attached, I checked the lighting coil and voltage regulator. The lighting coil ohm test is within spec. However I cannot any continuity from the regulator between red and white wire in either direction.
Got a used voltage regulator, but it failed the continuity test as well.
Can anyone help?
