alternator swap
I have a 1982 F100 with a 300 six. It has a 100 amp alternator and was wondering what it would take to put a 60 amp one in its place. The 100 amp one has different connections on it. Would I have to change some of the wiring other than the connections to change it to a 60 amp? There are plenty of 60 amp alts out there but very few 100 amp ones and they cost a lot more.

I have 4 wires that come out of the alternator. It is hard to tell exactly what color the wires are. I looks like one (this one has a plug end on it inside the rectangular housing which plug into the alternator) is orange with either a blue or black strip (goes to the f terminal on the voltage regulator). 2 wires out of the same housing which I think is tan with either a blue or black stripe. One of these wires goes to the choke on the carb. One large black wire with I belive a tan stripe that bolts by its self to the alternator.
The wiring has discolored over time and its difficult to tell for sure what the color is.
When I first got the truck I wanted to put a factory tach in it and had to change a little bit of the wiring that connects to some of the wires that come from the alternator, but I didn't change the wires that actually attach to the alternator.
