Alternator 55 AMP

55 Amp Marine Alternator for the older ski boats, this alternator has a built in voltage regulator, if yours has an external regulator it will need to be removed.

Mounting 'Foot" 2" wide

Adjusting "ear" 5/16" Threads inside

Pulley: single approx. 2 7/8 Dia.

Can be operated in either LH or RH rotation engines.

NEVER Install a 95 amp or larger alternator with stock engine/boat wiring designed for 55 amp alternators. To increase alternator size/capacity you need to upgrade to the proper size wiring!

Wiring:

Post for large output wire (typically #10 gauge)

Purple wire: To ignition circuit, (when key is on this wire "excites" the field)

Red wire: Needs to connect to constant 12v + typically run back to the starter solenoid battery cable.
