INSTALLATION & SERVICE MANUAL
TROUBLE SHOOTING
NOTE:
Many installation problems can be created by improper connections. Before proceeding with module or relay
replacement, be sure that all the wiring connections are correct and the battery/batteries are charged and
connected in the correct polarity.
Symptom/Problem
Won't connect the battery/batteries.
Won't disconnect the battery/batteries.
Keeps disconnecting the battery/batteries with the
ignition off.
No power through the relay.
Possible Cause/Cure
Be sure battery/batteries are connected in the correct
polarity and charged to at least 24.2 volts.
Check the 10 amp fuse feeding the module power.
Replace if necessary.
Check the 10 amp fuse feeding the module.
This is a normal function for the system to prevent
excessive draining of the batteries. Check for draining
loads. Turn off unnecessary loads.
Check the condition of the batteries. They may be
failing.
Check to be sure the relay has been closed by actuating
the dash-mounted switch. Connect a voltmeter between
the relay coil terminals to see if power and ground are
applied when the switch is pressed. (Both coil terminals
are normally grounded through the module.
External
application of power to either of the coil terminals will
damage the module. The relay may be operated without
the module by first removing the connections to the
module and then MOMENTARILY ap24 volts and
ground with test or jumper leads.)
If power has been applied in the correct polarity and
the relay is still open, replace the relay.
