So, any helpful sites on going from Gen to Alt?
Randy, have you thought to look in the Technical Resource Library (TRL)? There is a lot of information there regarding troubleshooting generators, or alternators, 3 Wire vs 1 Wire Alternators and why 3 Wire is better. Converting a gen to an alt, like the PowerGen. This information can be found in the TRL under the Engine section. Going with a 1 Wire might be an easy way to go, except that you will have to wire up your gen light to make it work. Since you have a lot of power options, something in the order of 100+ amps with a built in VR, as John says, is the way to go. There is also info there on where to find mounting brackets if you need to replace yours. Check out the Generator to Alternator link for some good info on what to look for in a Ford 3G alt. The link to the TRL is always right below the signature element for myself and jopizz, making it easy to find.
