DVOM.......................................................................... 1
1. CHECK FOR LOOSE OR BARE WIRES
Check for loose wires at each terminal connection
and for worn insulation or bare wires touching the
frame. Bare wires may cause a short circuit.
NOTICE
If any DVOM readings indicate a faulty wire, it is recom-
mended that the condition of the terminals and wire junction be
examined. A faulty wire should be replaced with one of the
same gauge and color and wired between the correct compo-
nents and wire tied to the harness bundle. The faulty wire
should be cut back close to the harness and the ends pro-
tected with vinyl electrical tape.
2. CHECK BATTERY CONDITION
Check for adequate battery volts (nominal 12 VDC)
by setting DVOM to 30 VDC range and place the red
probe (+) to the middle negative (-) battery post with
the green wire attached. Place the black probe (-) to
the first negative (-) battery post on the driver side
with the black wire attached. A reading of 11 VDC or
greater indicates adequate battery condition. No
reading indicates (a) a poor connection between the
probes and the battery terminals; (b) a faulty DVOM.
A voltage reading below 11 volts indicates poor bat-
tery condition and the vehicle should be recharged
before proceeding with the test.
NOTICE
Due to the resistance of the wires involved within the harness,
voltage readings may be somewhat lower than battery voltage.
A reading of 1 volt below battery voltage is acceptable.
3. CHECK GREEN POWER WIRE
Firmly attach black probe (-) to the first negative(-)
battery post on the driver side with the black wire
attached and the red probe (+) to the terminal on the
side of the fuse block where the green wire is con-
nected. A reading of battery voltage indicates that
the green wire is in good condition.
NOTICE
The green wire supplies power to the entire fuse block.
4. CHECK FUSE
Place the red probe (+) to each wire terminal on the
fuse block. A reading of battery voltage indicates that

the fuse is in good condition. No reading indicates a
faulty fuse; replace with a good 15 amp fuse.

ACCESSORY WIRING
After determining that there is power to the fuse panel,
and the fuse is good, continue checking the circuit using
the procedures previously used to check the power sup-
ply, i.e. loose or rusted connections, bare wires, continu-
ity of the wiring from terminal to terminal, operating
condition of switch, etc.
Use the wiring diagram (Ref Fig. 2 on page L-2), and
illustrations (Ref Figs 3, 4 and 5 on pages H-4, 5 and 6)
to check correct wiring and wire routing. If there is power
at the fuse end of the wire, there must also be power at
the other end of the wire at the switch or electrical
accessory, and eventually at the ground connection.
Electricity must flow from the fuse panel through the full
length of the circuit to the ground connection. Any inter-
ruption of electricity flow must be corrected, whether by
repairing or replacing the wire, the switch or accessory.

LIGHT BULB REPLACEMENT

To prevent premature bulb failure, do not touch new
bulbs with bare fingers. Use a clean, dry tissue or
paper towel to handle the glass portion of the bulb
Always hold bulbs with a clean, dry tissue or paper
towel. Natural oils from fingers will cause halogen bulbs
to fail prematurely.
Determine which bulb needs to be replaced. Reach
underneath light bar to access bulb from rear. Turn the
bulb socket a quarter turn counterclockwise to unlock
and pull out bulb. Insert new bulb and rotate quarter turn
clockwise to secure.
Locate bulb socket on backside of light bar (Ref Fig. 3
on page L-4) and turn bulb socket a quarter turn coun-
terclockwise to unlock and pull out bulb. Insert new bulb
and rotate socket a quarter turn clockwise to secure.
To replace the tail and brake light bulb, roll the rubber
bezel from around the edge of the taillight and remove
lens. Install replacement bulb and replace lens.
FUSE REPLACEMENT
To replace fuses, locate the fuse block under the driver
side seat. Pull out old fuse and replace with a new auto-
motive type fuse. Headlight and taillight bulbs and fuses
