Possible
Cause/Solution
Remove battery disconnect panel from cabinet /
console and with a multi-meter set on DC voltage,
measure between the red wire at pin # 2 and the
STEP 27
black wire on pin # 12. The voltage should read
the same approximate value as the batteries. If not
replace harness, refer to PARTS LINK#1 (page 7).
If the voltage reading is the same go to step 28.
With a multi-meter set on DC voltage, measure
between the red wire at pin # 2 and the brown wire
on pin # 1 while the switch is depressed. The
STEP 28
voltage should read the same approximate value as
the batteries. If not replace disconnect panel, refer
to PARTS LINK # 2 (next page8). If the reading is
the same go to step 29.
With a multi-meter set on DC voltage, measure
between the black wire at pin # 12 and the white
wire on pin # 4 while the switch is pressed. The
STEP 29
voltage should read the same approximate value as
the batteries. If not replace disconnect panel, refer
to PARTS LINK # 2 (page 8).
Possible
Cause/Solution
Check fuses on relay. If not blown go to step 32, if
STEP 30
blown replace with size fuse and retest. If fuse / fuses
re-blow go to step 31.
Disconnect harness from battery disconnect
panel inside of RV, replace fuse, if fuse re-blows
STEP 31
either attempt to find damage in the harness
and repair or replace harness, (see P# 1 link
page 7). If fuse doesn't blow then go to step 32.
Check battery voltage, the voltage must be greater
than 10.5 Volts DC for the latching relay to close or
STEP 32
open. If batteries are below 10.5 Volts DC, charge
batteries and retest. If the batteries are charged and
are above 10.5 Volts DC go to step33.
