TEST PROCEDURE 7 – Circuit Breaker
See General Warning on page 1-1.
1.
Place the key switch on the OFF position, the Tow/Run switch in the TOW position, and the Forward/Reverse
switch in the NEUTRAL position.
2.
Set a multimeter on 200 volts DC. With the batteries connected, connect the negative (–) lead to battery no.
8 negative post. With an insulation-piercing probe, connect the positive (+) lead to the tan wire on the back of
the circuit breaker.
3.
The reading should be 48 volts. If the reading is 0 volts, replace the circuit breaker.
TEST PROCEDURE 8 – Battery Pack Voltage (Under Load)
See General Warning on page 1-1.
1.
Before proceeding with this test procedure, the batteries must be connected and fully charged. Connect the
positive (+) lead of a 36 to 48-volt battery discharge machine (CCI P/N 101831901), to battery no. 1 positive post
and connect the negative (–) lead to battery no. 8 negative post. Record the voltage reading from discharge
machine.
2.
Turn the discharge machine on and record the voltage reading of battery pack while under load.
3.
A fully charged set of batteries in good condition should read between 47-49 volts while under load.
4.
A reading of 32-46 volts indicates discharged or failed batteries. Each battery should be checked with a
multimeter while under load.
5.
A reading of 32 volts or less will not activate discharge machine. If the voltage of the batteries is below 32 volts,
the batteries are deeply discharged or have failed.
6.
Recording the battery pack voltage reading while under load provides a more accurate diagnosis of the condition
of the batteries. When the discharge machine is ON, it places the battery pack under load and many times can
help determine if one or more batteries in the set have failed. Testing battery voltage while the batteries are not
under load will not always indicate the true condition of the batteries. For more information about the batteries,
refer to See Section 25 – Batteries: Electric Vehicles. .
