Installation
Installation
Before installing your new voltage regulator rectifier:
- Check the AC output of the stator.
- Replace any burned or corroded connectors on stator and regulator rectifier.
- Check and repair any melted wiring.
- Use hi-temp dielectric grease on all connectors.
This regulator connects differently than the original on many applications.
If your stator has 2 Yellow wires:
Our regulator Yellow wires connect to 2 stator Yellow wires (any order)
Our regulator 2 Red wires (into 1 bullet terminal) = Battery +
Our regulator 2-terminal connector Red wire = Charge warning light on dash
Our regulator 2-terminal connector Black wire = Battery - (ground)
If your stator has 2 Yellow wires and 1 Red wire:
Connect the 2 STATOR Yellow wires together, and connect one to our regulator Yellow wires (doesn't matter which one)
Connect the STATOR Red wire to the other one of our regulator Yellow wires
Our regulator 2 Red wires (into 1 bullet terminal) = Battery +
Our regulator 2-terminal connector Red wire = Charge warning light on dash
Our regulator 2-terminal connector Black wire = Battery - (ground)
If this configuration does not produce any charging output at the battery, the stator is an alternate winding configuration. Do not use the Red wire from the stator (insulate it and secure out of the way). Connect like the first configuration (If your stator has 2 Yellow wires).
Warning:
Risk of electric shock. Disconnect the battery before servicing.
Ensure proper installation by a qualified technician to avoid malfunction.
