Cause/Solution
Check fuses on relay. If not blown go to step 3, if
blown replace with same size fuse and retest. If fuse /
STEP 1
fuses re-blow go to step 2.
Disconnect harness from battery disconnect
panel inside of RV, replace fuse, if fuse re-blows
either attempt to find damage in the harness
STEP 2
and repair or replace harness, (see PARTS
LINK# 1 below). If fuse doesn't blow then go to
step 3

Check battery voltage, the voltage must be greater
than 10.5 Volts DC for the latching relay to close or
STEP 3
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 step 4.
With an assistant, press and hold momentary
switch, at the same time check for voltage across
STEP 4 the coil terminals (+ on the "I" terminal and
ground on the "S" terminal), If 0 volts go to step
5. If voltage is 10.5 VDC or larger between the
"I" & "S" terminals, replace relay.
Remove battery disconnect panel from cabinet /
console and with a multi-meter set on DC voltage,
measure between the red wire at pin # 3 and the
STEP 5
black wire on pin # 6. The voltage should read the
same approximate value as the batteries. If not
replace harness, refer to PARTS LINK#1. If the
voltage reading is the same go to step 6.
With a multi-meter set on DC voltage, measure
between the red wire at pin # 3 and the brown wire
on pin # 1 while the switch is depressed. The
STEP 6
voltage should read the same approximate value as
the batteries. If not replace disconnect panel, refer
to PARTS LINK # 2 (page 8). If the reading is the
same go to step 7.
