INTELLITEC
Possible
Cause / Solution
Verify that the relay is actually in the disengaged
(unlatched) state. With a test light, probe the larger
5/16" stud terminals on each side of the relay. Only
STEP 63
one terminal should be powered up in the
disengaged state. If both studs are powering up the
test light go to step 52. If only one 5/16" terminal is
powered up go to step 64.
Remove the battery disconnect panel from cabinet
/ console and with a multi-meter set on DC
voltage, measure between the yellow wire at pin #
11 and the black wire on pin # 12. The voltage
STEP 64
should read 0 Volts DC. If it reads 0 VDC then
replace switch panel, refer to PARTS LINK #2
(page 8). If the voltage reading is the same as the
nominal battery reading then go to step 65.
Disconnect the plug from the battery disconnect
panel, with a multi-meter set on DC voltage,
measure between the yellow wire at pin # 11 and
STEP 65
the black wire on pin # 12. If the voltage continues
to read 12 Volts DC go to step 41. If it now reads 0
VDC then replace switch panel, refer to PARTS
LINK #2 (page 8).
Leave the battery disconnect switch unplugged. At
the relay location, disconnect the yellow wire from
the relay. With a test light, probe the fuse for
STEP 66
voltage. If the test light powers up, replace the
relay and retest. If it does not, then probe the green
wire. If there is voltage present replace the harness,
refer to PARTS LINK #1 (page 7)
Possible
Cause / Solution
Verify that the relay is actually in the engaged
(latched) state. With a test light, probe the larger
5/16" stud terminals on each side of the relay. Both
STEP 67
terminals should be powered up in the engaged
(latched) state. If only one is powering up the test
light go to step 45. If both 5/16" terminals are
powered up go to step 68.
