When  you  have  inspected  and  repaired  any  wires  and  connections,  inspected  belts  and
replace as needed, and after you have determined that your batteries are properly charged,
set your voltmeter to 12V and connect the voltmeter’s negative lead to the BLACK ground wire
at the regulator. Normally, connection is accomplished by inserting the negative lead along-
side the ground wire in the regulator harness plug (see Figure 19) and the positive lead along-
side the wire referred to in each specific test. With the voltmeter securely connected to the
regulator’s ground, test for voltage at the points listed below.

1.

With the ignition in the OFF position and your voltmeter’s ground wire connected to
the regulator’s ground, check for voltage on the red (sensing), blue (field) and brown
(ignition) wires in the regulator plug by inserting the positive lead of the voltmeter
alongside each wire in the regulator harness plug. The voltmeter should read:

With the ignition in the ON position (engine not running) and your voltmeter’s ground
wire connected to the regulator’s ground, check for voltage on the red (sensing), blue (field) and brown (ignition) wires in the regulator
plug. The voltmeter should read:

* 11.5 - 12.8 VDC battery voltage at rest (no charging occurring). If your batteries are isolated and your RED (sensing) wire shows voltages other than those shown above,
make sure that the wire is connected on the “battery” side of the isolator. The RED wire must “see” the battery directly.

** 13.5 - 14.5 VDC battery voltage when charging.

If your readings differ substantially from the “Expected Readings” listed in the charts above, the regulator may be malfunctioning, or there may
be a continuity problem. Contact our technical support staff at (360) 435-6100. Keep your recorded readings in the spaces provided below the
“Expected Readings” so you can share them with the technical support person. If your readings match those listed in the charts, your regula-
tor should be working correctly. Continue with tests below to determine if your alternator may be the source of charging difficulties.If the pre-
ceding tests do not prove the existence of a failure within the regulator or alternator, we recommend you contact a licensed marine electrician
who can test your system for wiring and circuit damage or other system failures that could be responsible for charging difficulties. If you deter-
mine that repair service is necessary for either your alternator or regulator, please gather the following information before contacting our serv-
ice technicians.

1.

Model of alternator.

2.

Model of voltage regulator.

3.

Voltage readings on red, brown and blue wire at regulator with engine off, key on.

4.

Voltage readings on red, brown and blue wire at regulator with engine running at a fast ideal 1400 rpm.
