3.1. Verify the 10 gauge red wire from the charger receptacle is connected to the positive post of battery No.
1
(Figure 14-10, Page 14-13) .
3.2. Make sure the two nuts that secure the two 10 gauge black wires to the receptacle fuse assembly are
tight
(Figure 14-9, Page 14-13) .
3.3. Check the connections of the 18 gauge gray wire from the receptacle to the sense lead fuse, and from
the sense lead fuse to the onboard computer gray wire (Figure 14-9, Page 14-13) .
3.4. Remove the gray sense lead fuse assembly and check its continuity with an multimeter set to 200 ohms
(¾). The resistance should be less than 2 ohms.
4. With 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. 6 (Figure 14-10, Page 14-13) . Normal no-load voltage will
be 50 to 52 volts for fully charged batteries. The voltage of the battery pack must be over 32 volts DC in order
to allow the onboard computer to close the charger relay.
If battery pack voltage is too low to start charger,
see Section 13–Batteries, Charging Battery Pack With Low Voltage .
Test Procedure 2 - Onboard Computer
1. Check the circuit breaker on the front of the charger and reset if necessary.
2. Select a second charger that is normally connected to another vehicle and is known to operate properly.
Leave the AC cord of the second charger connected to the AC outlet that it normally is connected to. This will
ensure AC power is present.
3. Insert the DC cord from the second charger into the receptacle of vehicle that is not charging properly
4. If the second charger fails in the same manner as the first charger, then the vehicle charging circuit is not func-
tioning properly. See Troubleshooting, Page 14-8 .
5. Connect the first charger into another vehicle that is known to be functioning properly. If the charger per-
forms as it should, then the charger is not in need of repair.
• DO NOT BYPASS THE SENSE LEAD FUSE!
