Good evening, I got a 1980 Suzuki Gs 750 L, first voltage test was 12.57- started and it was 12.43, turn light on bright and it stayed at 12.12 to 12.14, not lower or higher, hope you can give me your thoughts, thank you for your time.
So I have a 04 Yamaha grizzly and when I put black lead on negative and check to see if it stops current I get same reading .5 volts? Is my rectifier bad?
