Hi,
The alt puts out alot af amperage and needs a #8 pos and #8 grd wire. I find that more amperage is blocked by a high resistance grnd at the mounting bolts. Also with a chrome alt you need to grind or file the chrome off so there is a good ground at the mounting bolts.
The fans need a relay to isolate them from the alt and ignition or they can back feed a voltage spike and blow the ign. On MSD igition you need a relay on the main power or the engine can run on from backfed voltage from the alt or fans, NHRA tech will check that the engine does not run on.
