I have a Massey Ferguson 150 with a Delco 3 wire alternator with external Borg Warner R-310 4 post external regulator which has two resistors on bottom. Does anyone have a wiring diagram? I have had it wired myself for 20 years, but due to strokes am having problems getting it wired. Thanks for any help. BUI
