Installation Voltage Regulators Instructions
You have bought a quality voltage regulator. This unit is engineered and built to give you maximum service when properly installed. The fact that you are replacing the voltage regulator indicates the possibility that some trouble may exist in the electrical system that caused the old regulator to fail. To avoid damaging the new regulator follow these instructions carefully.
IF CHARGING RATE IS LOW OR NO CHARGE AT ALL,
MAKE THESE TESTS:
1. Check battery water and general battery conditions to see if it will take and hold a charge. Check for specific gravity of 1.240 to 1.290 and make load test with a cell tester.
2. Check wiring for damage. Make sure all wiring connections at generator, regulator and battery are tight and free from corrosion.
3. Check fan belt for tension. Set to vehicle manufacturer’s specifications.
4. Run motor at medium speed, using a wire to touch one end to regulator base and other end to a good ground. If generator now charges, regulator is not properly grounded.
5. If, after the preceding test, the generator still does not charge, run the engine at medium speed and make the following tests illustrated.
FORD REGULATORS ONLY:
Connect a piece of number 10 or larger copper wire between the ARM terminal and the BAT terminal. Touch one end of another piece of wire to the FLD terminal and the other end to the ARM terminal. If the generator now charges, replace the regulator. If the generator does not charge, the trouble is in the generator.
