what amp is my alternator

I might find the answer before its posted, but heres my question., I just bought a 2001 p71 crown victoria. And it was an ex-trooper car, but -all the lights. Im gonna use it for a winter car and by another one with less miles but around the same year. Now do you think i would need to upgrade the alternator because im thinking it already is a heavy duty one because ex police cars had computers and lights so im thinking a stock Alternator would not have been able to handle al that,. So how do i tell what kind of Alternator it is, a stok one or heavy duty one.

I'd poke around with a flashlight and look for a data plate riveted to the alt.  My guess is it's HO, but I wouldn't go building a giant system w/o knowing for sure.

If you can't find anything on it you might try calling your local ford dealership - ask for parts/service and give them the VIN.  Maybe they can tell you.

Either a 130, 135, or 200amp alternator. You'll be able to tell by the cable sizes.

The 200amp alternator required a larger cable. The one we sell looks like 4 or 2g.
