I've already been searching this subject for a couple hours without finding a match yet.
Current external alternator dead and need to upgrade in a hurry to an internally regulated alternator. Seems like MAD Enterprises and M&H are sources to upgrade to a 10SI or 12SI model for conversion kits. My question is: With only a low power stereo and a planned addition of a cooling fan as accessories, what model 10SI or 12SI alternator show I ask for? I'd like to get a genuine Delco unit, but I'm sure the output characteristics and perhaps other variables are determined by what year/model/options of the vehicle they were built for. Any recommendations as to exact Delco part number to ask for based on my needs?

If you're going with a cooling fan then at least a 12SI alternator or use a CS130 alternator.

You mentioned MAD so go Here and near the bottom is a table with part numbers. Even AC Delco numbers!

To do the conversion you can connect the outer 2 wires and the inner 2 wires on the regulator plug. Then, install an alternator plug that has the wires the opposite way. The Tech Reference on this site has some good info.
