I"m trying to rewire an oliver 77 that had a motorcraft alternator that was bad. There was no voltage regulator on the system and I think the wire going to the coil is at the wrong post. The tractor ran fine other than battery would not charge and drained when tractor was off(within 4 hours battery dead.) Here"s how I have it wired now.
Alternator
FLD - Volt reg F
BAT - Ammeter to + Battery
STA - not connected
GRD - Grounded
Voltage Regulator
I - not connected
A - to Positive Battery (connected at starter switch)
S - goes to ignition switch to Neg side of coil, Pos side of coil goes to distributor (I think this should be reversed but it was running this way)
F - FLD
Questions: Do I need to change the wire to the coil?
Does the coil get power from the S terminal from the voltage regulator?
Thanks
Ryan
