ELECTRICAL ELECTRICAL SYSTEM TESTS
NOTE: Use the troubleshooting flow charts for the sequence of component testing and the following steps for test locations and procedures. Always refer to the wiring schematics when doing circuit testing for a better understanding of the circuit.
WARNING If there is no voltage, the battery has an internal open circuit. Connecting a charger or auxiliary battery to a battery with an open circuit can cause a battery explosion.
WARNING When the test involves turning over the engine or starting the engine, use test leads long enough to read the multimeter from the operator’s seat or standing clear of the machine.
If there is voltage, but is less than 12 volts, proceed to the next step.
STEP 2
NOTE: Use a multimeter for all tests. ALWAYS install the ground (-) test lead to a clean, bare metal surface on the engine or frame.
BATTERY TEST

2
Remove the positive (+) battery cable (1) from the battery. Connect the multimeter negative (-) test lead to the positive battery cable (1). Be sure the cable end is not in contact with any metal surfaces. Connect the positive (+) test lead to the positive (+) post (2) of the battery. The multimeter should read 0 volts.
1 G1007042
Set the multimeter to DC volt s. Connect the multimeter positive (+) test lead to the positive post (1) and the negative (-) test lead to the negative post (2) of the battery. The multimeter should read 12 to 13 volts.
If there is voltage between the positive battery cable (1) and the battery post (2), check the wiring for shorts to ground. If there is no voltage, recharge or replace the battery. Install the positive (+) battery cable (1) on the battery.
If there is no voltage, replace the battery.
