250A FUSED HARNESS INCLUDED
Cable sized to carry the full output, so it reaches the battery instead of heating up undersized factory wire
BOLTS INTO THE FACTORY LOCATION
161mm mount spacing, 55mm leg ID and a 17mm shaft, all matching the original, so no brackets or spacers
240A REPLACES 130A
Close to double the factory output, so a loaded touring system is no longer sitting at capacity.
TALKS TO THE ECU
Internal LIN regulator communicates exactly as the factory alternator does, with no ECU changes or resistor tricks
217A HOT, NOT JUST COLD
The honest working figure at 13.5V once up to temperature, rather than the cold bench rating alone
