    I have a 86 Ford F250 5.8l. it has the stock 45 amp 9I think0 alternator in it. I want to put a 70 or 90 amp alt. in it. The problem is it has the factory external voltage regulator in it. Th feed wire from the alt. to reg. is 14 or 16 ga. wire. How do you use a higher amp alt. with the factory volt reg when the feed wire is so small. It won't allow enough amps thru it :confused: . Any help would be great. Thanks

    Sorry the truck is a 1981 with external regulator. The site won't let me edit my post?
