Repair and Service Manual
Read all of Section B and this section before attempting any procedure. Pay particular attention to all Notices, Cautions, Warnings and Dangers.
If any DVOM readings indicate a faulty wire, it is recommended
that the condition of the terminals and wire junction be exam-
ined. A faulty wire should be replaced with one of the same
gauge and color and wired between the correct components
and wire tied to the harness bundle. The faulty wire should be
cut back close to the harness and the ends protected 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 (+) on the battery post with the green wire
attached. Place the black probe (-) on the battery post
with the black wire attached. A reading of 11 VDC or
greater indicates adequate battery condition. No read-
ing indicates (a) a poor connection between the
probes and the battery terminals; (b) a faulty DVOM. A
voltage reading below 11 volts indicates poor battery
condition and the vehicle should be recharged before
proceeding with the test.
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 power wire
Firmly attach the black probe (-) to the battery post
with the black wire attached and the red probe (+) to
the green wire terminal at the fuse block. A reading of
battery voltage indicates that the power wire is in good
condition.
The power 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. 11) 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 even-
tually at the ground connection. Electricity must flow
from the fuse panel through the full length of the circuit
to the ground connection. Any interruption of electrical
flow must be corrected, whether by repairing or replac-
ing the wire, the switch or accessory
