TEST PROCEDURE 1 – BATTERIES / VOLTAGE CHECK
See General Warnings, Section 1, 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 min-
eral content, can be found in Section 13 of this manual.
See Battery Care, Section 13, Page 13-4.
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 on page 11-19.
Batteries / Voltage Check with the IQDM Handset
1. Connect the IQDM to the vehicle as described in the IQDM Owner’s Manual.
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 connec-
tions or a battery installed in reverse polarity.
Refer to Section 13 – Batteries, for further details on
battery testing.
