TEST PROCEDURE 1 – Batteries / Voltage Check
See General Warnings on page 1-1.
NOTE: The batteries must be properly maintained and fully charged in order to perform the following test procedures.
Battery maintenance procedures, including watering information and allowable mineral content, can be found
in Section 16 — Batteries of this manual. See Battery Care, Section 16, Page 16-16.
The battery voltage can be displayed with the IQDM handset. If an IQDM handset is not available, proceed to
Batteries / Voltage Check without the IQDM Handset.
Batteries / Voltage Check with the IQDM Handset
1. Connect the IQDM to the vehicle. See Plugging the Handset into the Vehicle, Section 13, Page 13-1.
2. Access the Test menu and select BATT VOLTAGE by using the SCROLL DISPLAY buttons. The IQDM should
indicate at least 48 volts with the batteries fully charged. If not, check for loose battery connections or a battery
installed in reverse polarity. Refer to Section 16 — Batteries for further details on battery testing.
Batteries / Voltage Check without the IQDM Handset
1. 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. 4 ( Figure 11-6, Page 11-14 and
Figure 11-7, Page 11-15) or battery no. 6 (Figure 11-8, Page 11-15). The multimeter should indicate at least 48
volts with the batteries fully charged. If not, check for loose battery connections or a battery installed in reverse
polarity. Refer to Section 16 — Batteries for further details on battery testing.
