Remedy:
(1) & (2) Check the fuse. Check all connections from the regulator to the battery including checking for
correct wire polarity. Check that all connections are clean, tight, and secure.
Voltage Reading: 9 V – 12 V Charge Light: Off
Current Reading: 0 A Time of Day: Daytime
Possible Cause:
(1) Battery or fuse connection
(2) Defective GPR-25.
How to tell:
(1) Check the voltage at the regulator terminals labeled ‘Battery’ with a multimeter and compare with a
reading at the battery terminals. If there is no reading at the regulator terminals, the problem is
somewhere in the wiring from the battery to the regulator.
Remedy:
(1) Check the fuse. Check all connections from the regulator to the battery including checking for correct
wire polarity. Check that all connections are clean, tight, and secure.
10.2 Problems with Voltage
Voltage Reading: Inaccurate Charge Light: N/A
Current Reading: N/A Time of Day: Daytime/Nighttime
Possible Cause:
(1) Battery or fuse connection
(2) Excessive voltage drop from batteries to regulator.
(3) Incorrect calibration of the voltage meter.
How to tell:
(1) Check the voltage at the regulator terminals labeled ‘Battery’ with a multimeter and compare with a
reading at the battery terminals. If there is a voltage discrepancy of more than 0.5 V, there is an
excessive voltage drop
Remedy:
(1) Check the fuse. Check all connections from the regulator to the battery including checking for correct
wire polarity. Check that all connections are clean, tight, and secure. Shorten the distance from the
regulator to battery or obtain larger gauge wire. It is also possible to double up the existing gauge
wire (i.e. two wire runs) to simulate a larger gauge wire.
Voltage Reading: Erratic Charge Light: N/A
Current Reading: N/A Time of Day: Daytime/Nighttime
Possible Cause:
(1) Battery or fuse connection
(2) Electric noise.
Remedy:
(1) Check fuse. Check all connections from the regulator to the battery including checking for correct wire
polarity. Check that all connections are clean, tight, and secure.
(2) Electric noise from other electronics such as inverters or fluorescent lights may affect the current
reading. Attempt to trace the problematic appliance and fix the problem by relocation.
