1 Wire Alternator Options
I took the long way home on the '89 D100 318 to go 1 wire conversion and eliminate the computer controlled voltage regulator.

Swapped in a 1985 Ford double pulley Alternator with an aftermarket 1 wire conversion. Charge wire goes direct to the battery with an inline fuse.

Wired in simple parts store voltage gauge to a random 12 volt feed, simple and works good to follow voltage output.
Tried other external regulators but no joy. This setup works well for me.
