Remedy:
(1) Check fuse. Check all connections from the regulator to the battery.
(2) Electric noise from other electronics such as inverters or florescent lights may affect the current
reading. Attempt to trace the problematic appliance and fix the problem by relocation.
Voltage Reading: N/A
Current Reading: Rapidly changing
Possible Cause:
(1) Battery is full, array is producing full current, and there are functioning loads connected. This is
normal.
(2) The battery is too old or going bad and is unable to hold a charge.
(3) Poor battery or array connection.
How to tell:
(1) & (2) & (3) Check the voltage at the terminals with a multimeter.
(3) Check all wiring connections.
Remedy:
(1) & (2) If the voltage on the multimeter is rapidly increasing and decreasing, the battery is going bad,
the battery bank is too small, or this is a normal condition. Unfortunately, there is no way to differentiate.
Possible solutions are to test, individually, the physical battery status using a hydrometer. Consult your
battery manufacturer’s manual for more information.
(3) If the voltage on the multimeter is stable while the current reading is behaving erratically, it is the
battery connection between the battery and regulator. Check connections.
(3) Reconnect wiring correctly.
10.4 Miscellaneous Problems
Status: Charge light blinking when fuse is touched
Possible Cause:
(1) Fuse is loose.
Remedy:
(1) Securely attach fuse.
Status: GPR-25 buzzing
Possible Cause:
(1) Bad battery, array or fuse connection.
Remedy:
Check all connections and reconnect correctly.
Status: GPR-25 face plate hot to touch
Possible Cause:
(1) Defective GPR-25.
Note: It is normal for the faceplate to get warm during operation. The symptom of a defective GPR-25 is
only when then unit gets too hot to touch.
