NOTES:
1. CIRCUITS ARE IDENTIFIED BY WIRE GAUGE, COLOR & CIRCUIT NUMBER IE. 16 ORANGE 985 IS A 16 GAUGE WIRE WITH ORANGE
INSULATION & THE CIRCUIT NUMBER IS 985. THIS REFERS TO THE LINE IMMEDIATELY BELOW UNLESS INDICATED OTHERWISE.
2. FOR TRACTOR SERIAL #'S 162250 & ABOVE, CONNECT 403 PUSH ON PIN TERMINAL TO R-TERMINAL ON
ALTERNATOR (DO NOT USE 403 RING TERMINAL). ALSO DO NOT USE MULTIPLE CONNECTOR WITH CIRCUITS 409 & 425.
FOR TRACTOR SERIAL #'S 162249 & BELOW, CONNECT 403 RING TERMINAL TO R-TERMINAL ON ALTERNATOR
(DO NOT USE 403 PUSH ON TERMINAL). ALSO CONNECT MULTIPLE CONNECTOR WITH CIRCUITS 409 & 425.
FOR ALL UNITS USING A 24SI ALTERNATOR CONNECT TO THE "R" TERMINAL USING THE 4 POSITION PACKARD CONNECTOR.
