BOLTS INTO THE FACTORY LOCATION

161mm mount spacing, 55mm leg ID and a 17mm shaft, all matching the original, so no brackets or spacers

217A HOT, NOT JUST COLD

The honest working figure at 13.5V once up to temperature, rather than the cold bench rating alone

240A REPLACES 130A

Close to double the factory output, so a loaded touring system is no longer sitting at capacity.

WIRING UPGRADE REQUIRED

Supplied as the alternator only. The factory positive cable is not rated for this output and must be upgraded, along with fusing, before the unit is run.

TALKS TO THE ECU

Internal LIN regulator communicates exactly as the factory alternator does, with no ECU changes or resistor tricks

VEHICLE: Isuzu MU-X 4JJ1 4JJ3-TCX DSL
