choke light

I have 84 z28,i have noticed ever since I bought it this spring that in the morning when I drive it to work that the choke light fades on and off and also hear a faint buzz noise from under the dash as the chock light fades on and off . Is it a altenator problem? also when I leave work in the afternoon it doesnt happen....??????

Re: choke light

Yes it is an alt problem.

The alt needs a new "diode trio". Very easy to replace if you want to go that route, very few $$$.
