I have a 150 Massey Ferguson with Delco 4 wire with Borg Warner 4 terminal regulator which has two wire round resistors on bottom of regulator. I have had it wired for 20 years and it worked great, but I have had some strokes and can't remember how to rewire it. Does anyone have a wiring diagram for this. I know that #4 post goes to fuel gauge and F goes to F on alternator. There is a R on the alternator and the external post is the output from the Alternator through the amp gauge to the negative side of battery I think. I just can't remember the middle two wires on the regulator. I assume the R on the alternator plug is the exciter wire. Which wires goes to the middle two terminals? Thanks for any help.
