Quick Question about Charging??

[Mach1Guy]

I recently bought an '88 GT that has the electric fan wired for constant use.

I know these take a lot of juice, so I've found that with the A/C and radio or headlights going that the voltage drops off big-time.

I have a 135amp alternator (supposedly) and new battery but still have these issues.

Is there anything I can do to help regulate the power being used or boost the amount of power created to run all of these things?

The car also has underdrive pullies if that matters.

Thanks.

Underdrive pullies are probably not helping the situation at all. If you have the stock pullies try putting those on or buy an aftermarket alt. pully to compensate for the slowed accessories... that is if in fact you have a 135amp alt.
