Figure 12-4 Battery Discharge Test
4. Turn the discharge machine on and record the voltage reading of battery pack while under load.
5. A fully charged set of batteries in good condition should read between 46 and 49 volts while under load.
6. A reading of 32 to 46 volts indicates discharged or failed batteries. Each battery should be checked with a
multimeter while under load.
See following NOTE.
NOTE: If a 48-volt set of batteries is down in the 32 to 38 volt range, the discharge machine will activate but it will
think it is testing a 36-volt battery set.
7. A reading of 31.5 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.
8. 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 Electric Vehicle - Batteries on page 14-1.
TEST PROCEDURE 3 – Tow/Run Switch
See General Warnings on page 1-2.
NOTE: This is a voltage test.
If no voltage is coming to the Tow/Run Switch, inspect the red-to-pink wire spade connection at the solenoid.
Tow/Run Switch Test with the CDT Handset
1. With the Tow/Run switch in the RUN position, connect the CDT to the vehicle.
2. Immediately after the CDT is connected to the vehicle, the screen should display a copyright notice and the
CDT model number.
3. If the CDT display screen remains blank, the CDT port has failed. In this case, disconnect the CDT from the
port and connect it directly to the controller
(Figure 11-4, Page 11-29) .
