Diagnostics
If the Battery Guard® 1000 is fails to operate as intended, locate the device. The Battery Guard® 1000 provides a
diagnostic LED on the module that indicates several failure modes.
(Diagnostic LED located in the lower right corner)
1 Blink – Failed to disconnect
2 Blinks – Failed to reconnect
3 Blinks – Below minimum disconnect voltage.
This information can be very useful when trying to troubleshoot the Battery Guard® 1000. In the event that
there is an issue and the operator needs to bypass the disconnect. Remove the System load wire from the
Battery Guard 1000 terminal and move it to the same side as the positive battery feed.
WARNING: Before performing this task, disconnect all sources of power. Unplug the coach and turn off the
generator. Disconnect the battery(s) negative (‐) terminal.
