Alternator for Honda Goldwing GL1800 2001-2004 - 12V 75A

Fits Honda Goldwing GL1800 and GL1800A, 2001-2004

This 12-volt, 75-amp alternator is a complete replacement unit built to the output and mounting specification of the original equipment fitted to the Honda Goldwing GL1800 and GL1800A from 2001 to 2004. It weighs approximately 4.55kg (10lbs), matching the original unit.

It is a direct fit replacement requiring no modification to install, and replaces the Mitsubishi-built original carrying part numbers such as A5TA7599 and A5TB1079. A higher-output 100-amp version of this alternator is also available separately for owners running heavier electrical accessory loads. As a conventional alternator it requires no ECU coding or programming to fit - simply mount, connect and belt it up in place of the original unit.
