Re: Charging problems

either the rectifier regulator or the actual charge coils.. check your service manual for voltage specs and how to test.. test with a DVA. charge coils should be 100-300v at the red/yellow wires. and rectifier output should be about battery voltage.. anywhere from 9-15v is acceptable.

Re: Charging problems

Lets start simple. What is the voltage at the battery with engine not running? What is the voltage with the engine running? Have you cleaned all connections and grounds?
