[QUOTE="Monkeypants, post: 42789, member: 2708"] Good question. I have one bike that was restored locally here, I look to it as an example as it has far less add ons than my Oz Rapide, although I have since added a Chinamo and a 12 volt JG regulator to the package. This bike came to me with all black wiring and one twenty amp glass fuse on the ground wire. The previous owner had spent big$ having a total end to end mechanical resto of this bike done, but left the old Lucas E3L in place.The bike has a D distributor for ignition. After all of the agony of going thru the costly rebuild , he still had electrical problems with the bike. On nearly every ride he attempted, the battery would go flat, usually after blowing the fuse once or twice. In the end, he rode the bike just 550 miles in twenty years, at which point I bought it from him. The fellow who had done the resto work suggested I replace the generator, which I did. Interestingly, I found a couple of large invoices for electrical investigation work the Previous owner had done. They could not find any problem with the bikes electrical and the Lucas generstor checked out OK. I thougt I had the problem solved with the Chinamo, but it wasn't long before the old gremlin appeared. I finally found the problem on a night ride. I could see sparks flashing around the headlight switch , which wa a Lucas pattern replacement item. It occurred to me that a few circuit fuses would have made it very clear that this intermittent problem was in the headlight circuit. Then the previous owner might have enjoyed riding the bike for twenty years instead of sadly bringing it home in the back of a pickup truck each time!. [/QUOTE]
