SERVICE MANUAL

BATTERY GUARD 2000

RESET SWITCH

The 

RESET

 switch contains a LED and a momentary switch.  To test if the switch is faulty, unplug the harness from the 

switch.   Using a small jumper wire, momentarily short between the black and violet leads of the harness.  The 
Disconnect relay should click and be on.   If the system works using the jumper the RESET switch is defective.

Trouble Shooting

Before replacing or checking any components, check the 5 Amp system in-line fuse connected to  the Battery 
Disconnect relay.  If this fuse is good, be sure and check the wiring of the harness, in particular the ground connection 
under the hood.

A. System will not shut down with low battery.

1. Check orange wire for ignition "hot" only.
2. Check in-line fuse.
3. Check ground connection.
4. Check battery voltage.  Battery Guard will not turn off unless battery voltage is below 12.0 volts 

     and above 10.0 volts for more than four minutes.

5. Check for blinking "LED" on switch.

a. If "LED" is blinking press the switch and listen for relay to click.

(1) If relay does not click, replace module.
(2) If relay clicks, press the test switch and hold for 3 seconds.  
      Listen for relay to click again. 

(a) If relay does not click, replace module. 
(b) If relay clicks but power remains on in the van, replace relay.

b. If switch is not blinking, replace module.

B. System turns off prematurely.

1. Check battery voltage.  If battery voltage is below 12.0 volts Battery Guard 2000 will turn off.
2. Check fuse connection for corrosion and possible voltage drop.
3. Check ground connection.  
4. Check switch for blinking "LED".

a. If switch is blinking, replace module.
b. If switch does not blink, but power to van is turned off, replace relay.

C. System will not turn back on after disconnecting.

1. Check in-line fuse.
2. Check ground connection.
3. Battery voltage must be above 10..0 volts for Battery Guard 2000 to operate.
4. To start test, press switch and hold continuously for 3 seconds.
5. Check for blinking "LED" on reset switch.

a. If LED is not blinking, replace module.
b. If "LED" is blinking

 press the reset switch and listen for relay to click.

(1) If relay does not click, and "LED" continues to blink, replace reset switch.
(2) If relay does not click, and "LED" stops blinking, replace module.
(3) If relay clicks but power does not turn on in vehicle, replace relay.
