Possible
Cause/Solution
Check fuses on relay. If not blown go to step 22, if
STEP 21
blown replace with size fuse and retest. If fuse / fuses
re-blow go to step 9.
Remove the battery disconnect panel from cabinet
/ console and with a multi-meter set on DC
voltage, measure between the green wire at pin # 5
and the black wire on pin # 6. The voltage should
read whatever DC voltage as the batteries read
STEP 22
(typically around 12 volts). If it reads 0 VDC then
inspect the harness for damage, or replace harness,
refer to PARTS LINK #1 (page 7). If the voltage
reading is the same as the nominal battery reading
then replace battery disconnect panel, refer to
PARTS LINK #2 (page 8)
Possible
Cause/Solution
Check fuses on house relay. If not blown go to step
STEP 23
25, if blown replace with size fuse and retest. If fuse /
fuses re-blow go to step 24.
Disconnect harness from battery disconnect
panel inside of RV, replace fuse, if fuse re-blows
either attempt to find damage in the harness
STEP 24
and repair or replace harness, (see PARTS
LINK# 1 page 7). If fuse doesn't blow then go to
step 25.
Check battery voltage, the voltage must be greater
than 10.5 Volts DC for the latching relay to close or
STEP 25 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 26.
With an assistant, press and hold momentary
switch, at the same time check for voltage across
the coil terminals (+ on the "I" terminal and
STEP 26
ground on the "S" terminal), If 0 volts go to step
27. If voltage is 10.5 VDC or larger between the
"I" & "S" terminals, replace house relay.
