CHARGING SYSTEM TESTS
POLARIZING THE CHARGING SYSTEM:
1. Use a piece of wire 1/16 thick (minimum) and 8 inches long.
2. Hold one end of wire against screw head in regulator "BAT" terminal.
3. Touch other end of wire to screw head in regulator terminal marked "ARM" for a maximum of two seconds. CAUTION do not touch the "FLD" or any meatal part with the wire.
DETERMINE IF GENERATOR IS WORKING:
1. With the engine at a fast idle, and using a piece of 1/16 inch wire, hold one end on the "A" terminal of the generator and touch the other end to a ground. There should be a spark, if not generator is not working.
DETERMINE IF REGULATOR IS WORKING:
Test with engine at a fast idle.
1. Disconnect the wire from the "BAT" terminal and connect in an ammeter that will read 0-50 amps.
GROUNDED FIELD CIRCUIT
Disconnect the "F" terminal wire from the regulator. This opens the field circuit and the output should normally drop to zero.
If the output does not drop to zero, the generator field circuit is grounded either inside the generator frame or the wiring harness. To determine where the ground is, remove the lead from the generator field terminal. If the output fails to drop to zero, the field coils are grounded. If the output drops off, the ground is in the wiring harness.
POOR GROUND AT REGULATOR
With all wires in normal connected condition, and using the ammeter, connect one lead between the regulator base and one lead on the generator frame. If output changes, there is a ground between the generator frame and regulator base.
