Re: GEN Light Staying On
JimM, okay, here are my test results: Key Off; alt F = 0, alt R = 0, alt blue* (measured at regulator) = 0, alt white* (at regulator) = 0, alt red* (at regulator) = 12 volts, alt brown* (at regulator) = 0. Key On, engine not running; gen light on, alt F = 11 volts, 4th term on reg = 14 volts, no other changes. Engine Running @ 700 RPM; alt F = 5 volts, alt R = 7 volts and alt power = 14 volts. Engine Running @ 1,000 RPM; alt F = 3.5 volts, alt R = 7 volts & alt power = 14 volts. Plz note, this problem "came to light" after replacing both the alternator & original regulator because the headlights dimmed. Now, the headlights appear to be fine, but the GEN dummy light glows RED while Engine Running. Please let me know if more specific tests are needed or if you can draw a conclusion and recommendation with the above. ps: this is the first time I have ever tested the electrical charging system and it was fun! Thanks, Charlie *measurements were taken at the regulator as I was not clear where they would be on the alternator end.
