Possible
Cause/Solution
With an assistant, press and hold momentary
switch, at the same time check for voltage across
the coil terminals (+ on the "S" terminal and
STEP 11
ground on the "I" terminal), If 0 volts go to step
12. If voltage is 10.5 VDC or larger between the
"S" & "I" 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 12
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 (page 7).
If the voltage reading is the same go to step 13.
With a multi-meter set on DC voltage, measure
between the red wire at pin # 3 and the white wire
on pin #4 while the switch is depressed. The
STEP 13
voltage should read the same approximate value as
the batteries. If not replace disconnect panel, refer
to PARTS LINK # 2 (page 7). If the reading is the
same go to step 14.
With a multi-meter set on DC voltage, measure
between the black wire at pin # 6 and the brown
wire on pin # 1 while the switch is pressed. The
STEP 14
voltage should read the same approximate value as
the batteries. If not replace disconnect panel, refer
to PARTS LINK # 2 (page 7).
Possible
Cause/Solution
