Hi All,
I am working on a friend's immaculate "83" SS440 with about 1,600 miles on it. He bought it a little over a year ago. It starts and runs like brand new. The only problem is shortly after it starts running, generally after it warms up a little and at first only when you rev it up, all lights go very dim to completely out. In a little while they are all out all the time. It has had this problem ever since he got it. I have checked the wiring and I don't see any rub throughs or wires that look bad in general. It seems to be a function of running time. One more potential clue. It appears that at one time someone had handlebar heaters on this machine and took them off. I was curious if they could have stressed something out electrically. It runs great other than the lighting issue. I see all the lighting wires go directly into the CDI box. I was wondering if the lighting voltage section of it could be bad but still allow the machine to run.
Please let me know what you think.
