Sometime ago, my generator light came on in my camaro and I could hear a funny sound coming from my voltage regualtor. When I drive below 40-50 mph, the light barely flickers off and on, above that speed, it is on constantly and my lights also dim. I checked the Alternator and it was fine, so I replaced the Voltage Regulator and it still does the same thing. I also checked my belt to see if it was loose, but it is tight. I know nothing about electrical stuff when it comes to these things. What should I check next? Maybe a bad ground somewhere? Thanks for any and all replies. Oh, by the way, it is a 350, if that makes any difference.
