How to diagnose an electrical problem?
I recently got a 1982 fa50 thats been sitting for at least 3 years. It had been out in the open on its side for who knows how long. I cleaned out gas/oil tanks, new spark plug, new battery, air cleaner, carburetor, changed gear oil, and fixed a petcock problem. It now runs GREAT. Goes super fast and has no problem with leaks, randomly dying on me or anything like that.
HOWEVER the problem now is that the electrical stuff like the turn signal lights and horn etc. aren't working very well. They're just very weak and inconsistent. The speedometer and the tail light aren't working at all. The headlight and brake light work fine but get dim when I put on the turn signal. This was not a problem until after I got it running well. I tried to see if the battery needed charging but the needle on the charger didn't do anything, so I guess it doesn't need to be charged?
Before getting this scooter I was totally new to all this small engine/scooter repair and I have limited experience in electrical maintenance. So any good advice will be helpful. Thanks.
