I need to buy an alternator and im not sure what Amp to buy. I have a very simple electrical system and was wondering if you guys could help me out. Im not sure if I just add the amp draw of all my components or if I need more then my draw. Here is what Im running. I also dont know what head lights and parking lights draw for amps. This is an 87 Suzuki Samurai with a 408w setup for street/strip. I just bought a 75amp alternator but im starting to think it may not be enough.

Lights
MSD
COIL & UNILITE
Mallory 250 fuel pump
4 - 10" electric fans the papers say 9.5amps each

Not sure about the fuel pump, but those fans suck a lot of juice. If you are not in traffic a lot, I would say the 75 amp alternator would be enough.
