i recently did an alternator upgrade to the sierra and are having a few problems with it. The alt is from a ford EF falcon. and is 110amp.
the problem is when you apply a heavy load on it it shuts down and wont charge. it will run the engine and thermo and radio at low volume but as soon as you up the radio or turn on the spot lights it shuts down and the batteries get drained. what would cause this and how can it be fixed?
Thanx B4T

yeah i agree sounds like it isn't exciting
MUD, MUD, GLORIOUS MUD!
charge light on the dash doesnt work on this alt. did on the old one.
the alt has a battery wire and 2 others. one is connected to the battery as a voltage indicator wire and the other i think is conected to the dash light.
