Step-by-Step RMS 020-103771 Installation
1. Disconnect the Battery
Always start by disconnecting the battery to prevent accidental short circuits or electrical damage during installation.
2. Locate the Voltage Regulator
The voltage regulator is usually installed near the engine or battery compartment. Consult your vehicle manual to pinpoint its exact location.
3. Inspect the Electrical System
- Check the Stator: Use a multimeter to ensure the stator generates sufficient AC voltage.
- Inspect Connectors: Look for signs of corrosion or damage. Replace or clean connectors as necessary.
4. Remove the Old Regulator
- Disconnect all wires connected to the old voltage regulator.
- Unscrew the mounting bolts and remove the regulator from its bracket.
5. Install the New RMS 020-103771
- Secure the RMS 020-103771 regulator to the existing bracket or the one provided in the kit.
- Connect the wires according to the vehicle’s wiring diagram. Some setups may require a conversion harness.
- Apply dielectric grease to the connectors to enhance protection against moisture and dirt.
6. Reconnect the Battery and Test
- Reconnect the battery and start the vehicle.
- Use a multimeter to verify the output voltage, which should range between 13.5 and 14.5 volts at idle. This ensures the regulator is functioning correctly.
