that your batteries are properly charged, set your voltmeter to 24V and connect the
voltmeter’s negative lead to the BLACK ground wire at the regulator. Normally, con-
nection is accomplished by inserting the negative lead alongside the ground wire in
the regulator harness plug (see 

Figure 19

) and the positive lead alongside the wire

referred to in each specific test. With the voltmeter securely connected to the regula-
tor’s ground, test for voltage at the points listed below.

1.

With the ignition in the OFF position and your voltmeter’s ground wire con-

nected 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:

Red Wire

Brown Wire

Blue Wire

Expected Reading

2.

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:

Red Wire

Brown Wire

Blue Wire

Expected Reading

3.

With the ignition in the ON position (with engine running at 1,400 rpm fast idle) and your voltmeter’s ground wire connected to the reg-

ulator’s BLACK wire, check for voltage on the RED (sensing), BLUE (field) and BROWN (ignition) wires in the regulator plug. The volt-
meter should read:

Red Wire

Brown Wire

Blue Wire

Expected Reading

24 - 28V**

24 V

>25 V

Your Reading

* 23-24.5 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.

** 27 - 28 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 regulator should be working correctly. Continue with tests below to determine if your alternator may be the source of charging difficul-
ties.If the preceding 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 dif-
ficulties. If you determine that repair service is necessary for either your alternator or regulator, please gather the following information before
contacting our service technicians.
