Wiring diagram 55 amp alternator - 103-15, 104-19, 104-22
Wiring diagram maximum circuit resistance
The resistance of battery cables 1, 2 and 3 must not exceed 0.0018
Ù.
Note: Maximum cable size for 375 lucar terminals on the alternator is 65/0,3 mm (4,5 mm
2
) therefore twin
cables are required at the connection to the alternator.
(1) Max current draw for standard oil pressure switch is 0.42 amps (5 Watt lamp max).
