Storage Of Battery; Troubleshooting - E-Z-GO TXT FLEET Technician's 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.

STORAGE OF BATTERY

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. 10) 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 recommenda-
tions and instructions for the use and care of the meter.

TROUBLESHOOTING

In order to effectively troubleshoot the circuits that
include the horn, lighting, brake/turn signals and
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. 11).
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 connec-
tor and the ground wiring is satisfactory, the only possi-
bilities that exist are a burned out bulb or a poor contact
between the connectors and the headlight.
If power is not present but the other headlight functions,
a wiring problem is indicated between the two head-
lights.
COVER
In some cases where battery voltage is expected, the
DATA-H
easiest way to test the circuit is to set the DVOM to DC
SWITCH
volts and place the negative (-) probe of the DVOM to
the negative battery terminal. Move the positive (+)
RANGE
probe to each wire termination starting at the battery and
SWITCH
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
TRANSISTOR
voltage is expected, the same procedure may be used
SOCKET
except that the DVOM is set to continuity. Place the neg-
ative (-) probe on a wire terminal at the beginning of the
+ TEST LEAD
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

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.
