Test Procedures
2.
Access the Monitor menu and select BATT VOLTAGE by using the SCROLL DISPLAY buttons. The CDT should
indicate at least 48 volts. See following NOTE. If not, check for loose battery connections or a battery installed in
reverse polarity. Refer to Electric Vehicle - Batteries on page 14-1 for further details on battery testing.
NOTE: The voltage displayed through the CDT shows what the controller thinks it sees. If the controller is not
operating properly, it may display a different voltage from what the battery pack voltage (BPV) really is. Always
compare and confirm with readings obtained using a multimeter in the following procedure.
Batteries / Voltage Check without the CDT Handset
1.
If necessary, see Testing Basics on page 12-12.
2.
With batteries connected and using a multimeter set to 200 volts DC, place red (+) probe on the positive (+) post
of battery no. 1 and the black (–) probe on the negative (–) post of battery no. 6 (Figure 12-3, Page 12-14).
3.
The multimeter should indicate at least 48 volts. If not, check for loose battery connections or a battery installed in
reverse polarity. Refer to Electric Vehicle - Batteries on page 14-1 for further details on battery testing.

TEST PROCEDURE 2 – 48-Volt Battery Pack Voltage Under Load
See General Warnings on page 1-2.
NOTE: This is a voltage test.
1.
If necessary, see Testing Basics on page 12-12.
2.
Be sure the batteries are fully charged and that the electrolyte level is correct in all cells.
3.
Connect the tester leads to the positive (+) post of battery no.1 and negative (–) post of battery no. 6 (Figure
12-4, Page 12-15).
