Hey everyone,
FYI, this is for a 1977 stock bike.
My battery died last saturday and upon investigation it turns out the slip ring resistance was ~1.5 ohms.
So I got a new rotor from custom rewind in the mail today and slapped it on. Before I put it on I checked the slip ring resistance and it was 5 ohms. Nearly perfect.
After installation I performed two tests.
1) I turned the key to the on position and measured current leaving the battery. It was 5 amperes with no lights on. That is too high.
2) I started bike and checked voltage on battery. It was 17 volts. I immediately killed the bike.
So what gives? It looks like I am overcharging. How can I be getting 5 amperes through the rotor when the resistance is 5 ohms and the battery is 12.7 volts. I should be getting somewhere between 2 and 3 amperes. No more.
Is it possible my voltage regulator is bad. Furthermore, is it possible that a bad voltage regulator prematurely killled my first rotor?
Best,
Adam
