2. Disconnect Inverter/Charger control cable at the 6
position connector and the chassis harness at the
4 position connector at the Ground Box. There
should be continuity between the following:
a. 6 pos. terminal 3 to 4 pos. terminal 1
b. 6 pos. terminal 4 to 4 pos. terminal 3
c. 6 pos. terminal 5 to 4 pos. terminal 2
d. 6 pos. terminal 6 to 4 pos. terminal 4
3. If wiring is found to be good, the LED printed cir
-
cuit card is likely to be bad.
Interlock Cable suspected to be bad or vehicle thinks
charging is in progress, but it is not:
1. Disconnect Interlock (2 position) connector on the
Inverter/Charger control cable.
2. Turn on machine.
3. There should be Vbatt present on the Interlock
connector socket 1.
4. Turn off machine.
5. Disconnect Inverter/Charger control cable at the
charger.
6. Inverter/Charger connector (8 position) pin 6
should have continuity to Interlock connector pin
2 and then to ground module socket J1-29.
Ground Module powered while key is off or similar
behavior:
This condition can be caused by various ground module
outputs getting shorted to battery. If not done already,
cycle power and check for fault codes. If no fault codes,
perform the following:
1. Disconnect the Inverter/Charger control cable at
the 8 position connector and the 2 position Inter
-
lock connector.
2. Set digital multimeter to diode check or continuity
check to check diode in Inverter/Charger control
harness. If the meter does not have these features
a low range Ohm scale (20 Ohms for example) will
work.
3. Place red lead on 8 position connector pin 1. Place
black lead on Interlock connector pin 1.
4. Meter should read an open. Swap leads. Meter
should read a short. If either condition is not good,
replace Inverter/Charger control cable.
