What a day! Got off work at UBC at 3pm and was on the way home to the Westend. The bike was running perfectly for an '81 cb650. I managed to get almost half way up Burrard Bridge and then thats it. Bike dies right there! NO sputter. No cough. Cars are now flying by as I try to roll over to the curb lane. Hear a few hard braking from behind but what can you do. Manage to make to the middle of the bridge and roll down the other side and off the bridge. It looks like there is no electrical !!! All of a sudden the whole electrical system is non exsistant; no signal power, no oil/neutral lights. Nothing. Does anyone have any ideas as to what I should look for? First thing is to check the battery although the bike started fine 10 minutes earlier. It wouldn't even turn over while trying to jump it while rolling down hill. The headlight doesn't even come on now. What to do? Thanks for any help offered.
