Alternator question
What is the difference between the heavy duty and the standard alternator in a 92 F150?
The reason I ask is I bought a voltager regulator for my truck and it turns out the regulator is for the Heavy duty and not the standard alternator. I have since gone and bought the standard one, but haven't had time to install it.
I am not driving the truck right now so it hasn't been run with the HD voltage regulator but would it hurt the alternator if I ran it with the HD regulator?

I did some checking to try to ensure I did not tell you something incorrect. For your 92 F150, Ford offered two alternators: one rated @ 75 amps and one rated @ 80amps. The material I saw showed both units as taking the same wiring harness and same voltage regulators.
Obviously, the 80-amp unit has more capacity, but not grossly so.
I did, however, find a listing for a 100-amp alternator used in XLT Lariats as a special order option. It does, of course, take a different wiring harness and voltage regulator.
If you can post the part numbers of the two voltage regulators, I will be glad to try to sort them out for you, with corresponding Ford numbers.

Thanks for the help, I just broke down and took the alternator out (had to cut a bolt due to an oversized radiator on my part) and took it to the parts store and got the correct rebuild kit for it.
