Perkins Phaser 1004 Series Alternator

High quality aftermarket Perkins Phaser 1004 alternators, earth and insulated returned, fit all versions (including marine) of these engines set up for a 'three lug' mounted alternator or 'two bolt'. The adjuster arm securing bolt is at a 120 or 180 degree angle to the mounting arms as can be seen from the photos and diagram and note that the mounting bolt is on the right. These alternators take the earth (-) connection from the mounting to the engine block. Whereas the 'isolated earth' alternator requires a separate cable to supply an earth. Electrical output connections are for battery (+) and alternator warning lamp and an AC terminal for a tachometer.

For the alternators not supplied with pulleys the existing one can be re-used.
