Read all of Section B and this section before attempting any procedure. Pay particular attention to all Notices, Cautions and Warnings.
STORAGE OF BATTERY
B
A battery that is removed from service for storage must
be cared for as follows:
For battery removal see 'Battery Removal' in Section B.
Charge fully. Cover terminals with petroleum jelly to pre-
vent oxidation (use commercially available battery pro-
tectant when installed in vehicle). Store in a cool place
not below 32° F (0° C) or above 80° F (27° C) Battery
should be charged every 30 days using a 2 amp trickle
charger.
DVOM (DIGITAL VOLT OHM METER)
The DVOM shown (Ref. Fig. 9) is representative only,
the actual model may vary depending on availability,
and is available through the Service Parts Department
as P/N 27481-G01. For the purpose of this section, the
red probe (+) and black probe (-) are used. Any DVOM
may be used, however the controls, displays, accuracy
and features may vary depending on the make and
model. Always follow the meter manufacturer's recom-
mendations and instructions for the use and care of the
meter.

gauges, the technician must be able to use the wiring
diagram and a DVOM.
The wiring diagram shows the path followed by a volt-
age or signal from its origination point to its destination.
Each wire is indicated by color and is divided into the
main harness and the dash harness (Ref. Fig. 10).
The technician should use simple logic troubleshooting
in order to reduce the number of steps required to iso-
late the problem.
Example 1: If the vehicle will not start and none of the
lights function (or burn dimly) the battery should be
tested before trying to troubleshoot the lighting circuit.
Example 2: If a problem occurs in the lighting circuit
that results in only one of the headlights not working,
there is no reason to check battery wiring or the fuse
since it is obvious that voltage is present. Since bulbs
will burn out over time, the obvious place to start is at
the headlight that is not functioning. If power is present
at the connector and the ground wiring is satisfactory,
the only possibilities that exist are a burned out bulb or
a poor contact between the connectors and the head-

light.
If power is not present but the other headlight functions,
a wiring problem is indicated between the two head-
lights.
In some cases where battery voltage is expected, the
easiest way to test the circuit is to set the DVOM to DC
volts and place the negative (-) probe of the DVOM to
the negative battery terminal. Move the positive (+)
probe to each wire termination starting at the battery
and working out to the device that is not working. Be
sure to check both sides of all switches and fuses.
When no battery voltage is found, the problem lies
between the point where no voltage is detected and the
last place that voltage was detected. In circuits where
no voltage is expected, the same procedure may be
used except that the DVOM is set to continuity. Place
the negative (-) probe on a wire terminal at the begin-
ning of the circuit and work towards the device that is
not working with the positive (+) probe. When continuity
is no longer indicated, a failed conductor or device is
indicated
