I'm getting ready to add a bid of electrical gear into the car. Heated seats, two amps, some led interior lights, alarm and keyless push button start. I'n prep for this I replaced my 55 amp alternator with a higher output one.

I purchased an EMPI 90amp usa made alternator. Since installing my alternator, the alternator light comes on when i start the car. Once I give it some rpm's over 1200 it goes away. Once in a while the light will stay on. Next time I start the car it will go out.

Maybe a voltage regulator? Its in the alternator, so is this brand new alternator bad? Do i need to replace the whole thing? Or can i get a voltage regulator for it?

I searched the forums and found a tip from dr. clock to reverse the + and - on the light. That did not work and caused the tach to go nuts.

Also, does anyone know how many amps the car pulls with everything on? Would the 55 amp be enough. I know the heated seats pulls 10 amps each. So i'm thinking 55amps is not enough.

Nick,

What you are saying is an indication that the Empi (poor quality) Alternator is malfunctioning. Your best off buying a good quality Bosch unit. We had one of those Empi alternators go out and peak charge at 18 volts. When this happened every electronic part, including the Redline fuel injection ECU fried. It just is simply not worth the savings of buying an Empi part.

Good luck.
