TEST PROCEDURE 1 – BATTERY VOLTAGE
See General Warning, Section 1, Page 1-1.
1. Check the wire connections between the vehicle and battery charger
(Figure 6-2, Page 6-3)
.
1.1. Verify that the 10-gauge red wire from the battery charger is connected to the positive (+) post of
battery no. 1 for Turf 2/252, Carryall 2/252 and XRT 900 vehicles, or the large post of the solenoid
(battery side) for Carryall 6, Villager and TransPorter vehicles.
1.2. Verify the connection of the 10-gauge black wire from the onboard computer to the 10-gauge black
wire from the battery charger.
1.3. Check the connection of the 18-gauge gray wire from the charger to the onboard computer gray
wire.
1.4.
Turf 2/252, Carryall 2/252 and XRT 900
Only:
Check the fuse in the 18-gauge gray wire.
2. With a multimeter set to 200 volts DC, measure the voltage of the battery pack between the positive (+)
post of battery no. 1 and the negative (–) post of battery no. 8
(Figure 6-5, Page 6-11)
. Normal no-load
voltage should be between 50 and 52 volts for fully charged batteries. The voltage of the battery pack
must be over 34 volts DC to allow the onboard computer to close the charger relay
.
If battery pack voltage
is too low to start charger, temporarily bypass the charger relay.

Low Voltage on page 6-31.
