Question about 1981 Suzuki Gs 550 L
The alternator is puttin out 20 volts of juice instead of the 13-15.5 it should. is this causing the battery to drain and the turnsignals not to work when the battery gets worn down? thanks for any help
1981 used selenium rectifiers which were fairly low amperage. Not likely that overvoltage is the problem, but rather a failed rectifier and not changing to DC voltage (half wave). Get a 50-amp silicon rectifier from Radio Shack and replace it. Better yet, if you now have a headlight law in your state, change to a 50-amp bridge rectifier and gain more charging from the same alternator... be sure to get some help with the conversion from simple rectifier in-line to the battery and a bridge rectifier connecting both battery terminals to both alternator and ground.
