Test Procedures
EXCEL SYSTEM TROUBLESHOOTING:
WITH ERIC CHARGING
installed in reverse polarity. Refer to Batteries: Electric Vehicle with ERIC Charging on page 30-1 for
further details on battery testing.
NOTE: The voltage displayed through the IQDM 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 IQDM Handset
1. If necessary, see Testing Basics on page 28-16.
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 28-8, Page 28-18) .
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 Batteries: Electric Vehicle with ERIC Charging on page 30-1 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 28-16.
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
28-9, Page 28-19) .
