1978 Corvette generator light glowing with car shut off
I'm working on a C-3 1978 Silver Anniversary Corvette. One issue I have is with the "GEN" lamp showing a slight glow, even with the key shut off, doors closed, and no known parasitic drain in use (Radio, alarm, etc.) I'm not totally familiar with the car; and it has 90K on the clock which appear to be accurate. Any help would be appreciated!

I would check the alternator. Could be one or more diodes or the regulator is bad.

Re: 1978 Corvette generator light glowing with car shut off
Thanks DeltaP, After I posted the question it occurred to me to get the alternator & whole charging system tested. I can't do it right now as the interior is being replaced, and it would be difficult to drive 15 miles to the nearest parts stores for a diagnostic test. I'll do that as soon as I get it back on the road.

Just to clarify.... just remove the 2-wire plug, not the single wire with the bolt-on terminal at the end.

Re: 1978 Corvette generator light glowing with car shut off
Thanks to all who responded!! We got it fixed, using the KISS method. I took it to 2 different parts chains and both tested it; It worked perfectly, and was producing 14.95V. When we put it back in place, & hooked everything up, the light remained OFF. I'm pretty sure it was just a bad ground on a 34 year old car, with 90,355 miles. HOODATHUNKIT??
Thanks guys! BTW, We're giving this 25h Anniversary Edition Corvette away July 21, 2012 at the 25th Annual Kansas Veterans & Family Reunion in support of the Honor Flight Program for WWII veterans & The Wounde Warrior Project for our returning veterans coming back from Afghanistan & Iraq. A $20 donation gets you registered to possibly own it! PM me for details.
