Hi,

I have a Maxima '94 and recently I changed my alternator due to the fact it was the stock in it and it was 11 years old. I have an optima battery in the trunk and 2 power caps 1.5 Farrad for my system which is Rockford Fosgate amps for bass and the speakers inside and i have 2 10" subs. My question is the following, both batteries are at 13V when the car is off or on so i guess no power leak involved but my clock dims if i wait at a red light. What could be the problem? I do have an isolator for my 2nd battery. My alternator pushes 90 AMP.

Yes i do have a volt meter. I haven't tryed to check when the system is pumping on idle . . and how do i properly check the ground beside check if it's connected ot the ground.
