first, be positive you have 12.5 or better battery power.. a bad battery might read OK until you load it. Um, doesn't your bake have TWO batteries? maybe the other one is dead? I don't think a headlight relay came stock so check into that. Regulators have been known to crash but the bike should start if the batt is good. when my Bassa had a bad reg and the batt drew down the tach was the first sign, it fluctuated then died. also iit seems like there should be more than 3 relays? Seimens relays have a bad rep, get new ones from dpguzzi.com or an auto parts store.
