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.
