• Positive (+) lead to an unpainted, grounded
surface on the truck frame.
The voltmeter must show no more than 3V.
4. If a reading of 3V or more is received in the
previous steps 2 or 3, proceed as follows:
a. If applicable, remove bolts securing the battery
to the truck. Remove battery from the truck (see
page 203.)
b. Thoroughly clean battery (see
c. Reinstall battery. If applicable, securely fasten
bolts to battery box frame on the truck.
d. Repeat steps 2 and 3 to see if the problem has
been eliminated.
e. If excessive voltage is still found, check the
battery for internal leakage.
To test for shorts from components to frame:
1. Press red OFF button "O" on the keypad. Depress
main ON/OFF switch to the OFF position.
2. Disconnect the battery connector from the truck.
3. Using an ohmmeter and measure the resistance to
an unpainted, grounded surface on the frame at
B+, B-, and all fuses:
A resistance reading of less than 100,000 ohms
indicates a short to the frame. If this condition
exists, find the source of low resistance or short to
frame using the following step 6.
4. If applicable, remove bolts securing the battery to
the truck. Remove battery from the truck (see
page 203.)
The voltmeter must show no more than 3V.
5. Connect the battery lead to the truck.
6. Using an ammeter to measure the leakage current
to the unpainted, grounded surface on the frame at
B+, B-, all fuses and all motors. If the current is less
than 0.001 ampere (1 mA), the truck system
passes. If the current exceeds 1 mA, go to step 6.
