I have a 1973 Yamaha DT 250 with no spark. I have a suspicion that the magneto has gone bad, but the wiring harness is a mess and the coil doesn't look so good either. I can't get a reading on my multimeter anywhere, so I figured I would start at the stator and then work my way to the plug. Where should I put the test leads of my multimeter and what numbers should I expect? Also, should I be able to get any voltage anywhere if I kick the bike over while using the voltmeter? Thanks for any help you can give.
