I appreciate any input I can get.... it all helps.

My original alternator was a 61A (maybe 62A?) Still, an 80A can put out more current -- but isn't it supposed to put out whatever the load calls for? In other words, it's not going to pour out 80 amps all the time, only the amount asked for by the truck. That's my understanding, though I may be wrong.

You are correct that I did not increase any wire sizes. I do not know which wires, specifically, would need to be beefed up. Can you offer any advice about that?

The fans are powered by a relay wired to the junction block on the fender -- effectively the + batt post -- not through the fusibile link.
