Quality aftermarket 12 volt 65+ amp, 'high output' alternators fit all versions (including marine) of Perkins 4.108 engines set up for a 'three lug' mounted alternator. The adjuster arm securing bolt is at a 120 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 or left (see photos). Options
- The standard alternator takes the earth (-) connection from the mounting to the engine block. Whereas the 'isolated earth' alternator requires a separate cable to supply an earth.
- Supplied with cooling fan and pulley for either 12mm (7/16" inch) or 13mm (1/2" inch) alternator belt.
- Electrical output connections are for battery (+), alternator warning lamp and an AC terminal for a tachometer.

We include with the kit a packet of the correct electrical spade connectors and also a wiring diagram to help with fitting.

Easy to install and pretty straight forward wiring process. The alternator is a massive improvement on the old Perkins standard 40amp and puts out good amps at lower engine revs which is handy. Very happy with this product and recommended. Price, postage and delivery to Aus was excellent!
Good product. Excellent fast service.
Seems a decent item. Delivery and packaging was good.
It's kicking out quite decent amps at relatively low revs. More amps than expected.
