If voltage is not present on the RED, the BROWN and the Positive Battery Sense Wire, the regulator will not

work. If voltage is as expected at the RED the BROWN and Positive Battery Sense wire, and there is zero, or an

unexpected voltage reading at the BLUE wire, contact our technical support staff at +1(360) 435-6100, or e-mail

us at [email protected].

If all voltages at the regulator meet expectations, yet the alternator is not producing charging current, test the

alternator. The following tests are recommended for determining alternator functionality.

Alternator Testing

TEST #1 - The following test is used to isolate the alternator and determine if the failure is a result of the

alternator. Once again, testing at either the alternator or regulator is only effective if the wiring, fusing and

batteries have been determined to be in correct working order. The alternator and regulator can be tested for

function by determining if a magnetic field exists at the alternator's pulley shaft or rear bearing. To test:

With the ignition in the OFF position, place the tip of a non-magnetic steel screwdriver near the nut on

the pulley shaft or near the rear bearing of the alternator. There should be no evidence of a magnetic

field pulling the screwdriver toward the alternator. (A slight amount of magnetism may be present, due to

residual voltage in the alternator).

Engage the ignition, without starting the engine, to activate the voltage regulator. If an oil pressure switch

is used, a jumper between the RED and BROWN wires in the Ford-

style plug will activate the regulator.

After allowing time for the regulator's start-up delay, place the head

of a steel screwdriver near the nut on the pulley shaft or near the

rear bearing of the alternator. There should be substantial magnetic

pull. If a magnetic field is present, the voltage regulator, alternator

brushes and rotor are likely to be working properly.

If there is little or no magnetic pull at the pulley shaft or at the rear bearing,

initiate the following test:

With the key off and the engine off, remove the large harness plug from the

regulator.

Insert the end of a short length of electrical wire to the RED

connector slot of the regulator harness and the other end of the wire

to the BLUE connector slot. This bypasses the regulator and tests the alternator and the harness.

Using your steel screwdriver, inspect for a magnetic field as described above.

With your voltmeter, check for voltage on the blue wire at the alternator. If voltage does not exist, the

harness may be at fault. If voltage does exist at the harness, but no magnetism is present, the alternator is

likely to be malfunctioning.

4. If a magnetic field is present. Both harness and alternator brushes and rotor appear to be working

properly. If no magnetic field is present, proceed with the next test.

Testing the actual output of the alternator is known as "Full Field Testing". This can be accomplished by jumping a

positive 12VDC current to the field terminal at the rear of the alternator. This test eliminates both the regulator and

the harness, making it easier to isolate your investigation to the alternator.

CAUTION: Ensure that all voltage sensitive equipment is turned off prior to starting the engine. Voltage is

unregulated during this test and could damage sensitive electronics. DO NOT let the engine run any longer than

necessary to detect charging. If the system is not charging, remove the alternator and have it inspected by a

qualified alternator shop, or call Balmar for warranty evaluation. To test the alternator:

Clip a jumper wire to the positive post of the alternator, or on the battery side of the isolator (if an isolator is

in use). Use a SHIELDED alligator clip for post attachment. Unintentional contact between the alligator clip

and the alternator case could result in damage to your electrical system.

2. Disconnect the field wire from the rear of the alternator and attach the other end of the jumper wire to the

alternator's Field terminal (F). CAUTION: Do not allow the wire to contact the case while it is attached to

the positive post. The case may be grounded and severe damage could occur.

The regulator is now bypassed. When the ignition is engaged and the motor is started, the voltage should
