Electrical problems, any ideas?

[danh@xxxx]

I may have posted this before, but it hasn't showed up yet so I 
thought I'd post it again to be sure.

I finally getting sick of putting up with a handful of electrical 
issues in the DeLorean I bought a few months ago. Before I even 
start to try to diagnose the problems I thought I'd post a 
description here to see if anybody can give me a point in the right 
direction. Here's what I'm encountering:

-AC Vent fan doesn't operate consistently, it works fine for a short 
while and then cuts in and out intermitedly.

-If I put a blub in the front right turn signal, the turn signal 
causes the interior instrument lights to blink in addition to not 
working at all when the headlights are turned on (it just stay's on). 
This is currently "fixed" by removing the front turn signal bulb.

-The rear-defroster light is always on, it used to be always off. 
I'm not really sure how the rear-defroster works on a Delorean; I 
can't find a switch to turn it on, so I'm assuming it should only 
turn on when the heater is set to defrost.

-I have a lame decuelier (spelling?) alternator that drops well below 
13 volts when the AC is on. What alternator do you guys recdommend? 
I've seen upgrade kits advertised on the net for around $250 which 
seems like way to much to spend on an alternator. Are there any hi-
powered alternators that will bolt on without any extra mounting 
stuff?

Thanks in advanced,
