[Gene1949]

I "repurposed" a late Ford Taurus SVO alternator. 130 amp 3 wire internally regulated. At $20 been on the car for 15 years and many miles.
It's physically smaller than the GM or the original generator and the power output at low rpm (with the smallest pully you can find) its hands down the better choice.

The Op is absolutely correct in hooking the sensing wire as close the load center as possible.
I wired the '49 using the fuse/relay box off a 2000 Ford. All those old switches and the ignition now do pilot duty. I put the sensing wire on the main feed at that load center.
