Hi,
I have a Boyer Mk III on my 73 850. The last time I rode the bike months ago it was missing a bit with a Boyer pickup plate that I'd added homemade lead wires to. On that pickup plate I had unsoldered the original leads and replaced them with screwed on wires with ring terminals, etc. as I'd heard recommended several times on various forums, etc. I did this because I was getting an intermittent misfire.
When I went to investigate things I noticed that I was getting sparks when I wiggled the leadwires and figured I had a bad crimp in there and so removed both leadwires and recrimped all the connections.
After reinstalling the recrimped pickup plate I'm not getting any spark when kicking the bike over with the spark plugs out. If I disconnect the points wires from the pick up plate and touch the ends together I get a spark every time.
I tried putting on a spare pickup plate (actually the original pickup plate that I ran on the bike for 90,000+ miles) that I'd pulled off the bike 5 years ago. I had pulled it off because I was getting an intermittent misfire and putting on my then unused spare pickup plate (the pickup plate that I've attached new leadwires using screws, etc. now) This had cured the misfire then.
I get absolutely no spark with that pickup plate either. It was working five years ago, I was just getting an intermittent miss while riding the bike. I also put on my spare unused rotor and the results are the same.
It seems both pickup plates are totally dead? I'm thinking about buying a spare pickup plate, but it seems unlikely that both pickup plates would totally die like this. I can't think of any other way I could get a spark every time when touching the points wires together, but not at all when kicking over the bike.
Thanks,
Eric
