3.11 BATTERY CHARGER/INVERTER (OPTION)
The Battery Charger/Inverter is located on the top of the
chassis at the rear of the machine. Raise and secure scis
-
sor arms with arm prop to gain access to the charger.
Battery Charger/Inverter Troubleshooting
The Fault LED Flash Codes are the same as the Battery
Charger (see Battery Charger Troubleshooting on pages
3-29 and 3-30).
For further specification and troubleshooting informa
-
tion refer to the manufacturers’ Charger/Inverter
Owner’s Guide shipped with the machine. Publication -
RM1024-JLG - Part # 3128406.
Use the information below to supplement the informa
-
tion in the Inverter/Charger manual. First, go through
the troubleshooting in the Owner’s Guide (JLG part
number 3128406), then use the procedures below. For
control of the Inverter/Charger there is an 8 position
connector on a cable entering the case of the Inverter/
Charger. Looking at the pins of the connector, terminals
are numbered clockwise starting with number 1 nearest
the notch. Terminal 8 is in the center.
No charge voltage:
1. Disconnect control cable from Inverter/charger.
2. Turn on machine.
3. Inverter/charger control cable 8 position connec
-
tor socket 1 should have Vbatt present. If it is not,
check charger interlock connector, 2 position,
socket 1. If voltage is present there replace the
Inverter/Charger data interface harness. If Vbatt is
not present at the 2 position connector socket 1,
check the circuit through the chassis harness back
to Ground Module terminal J1-19.
Loads will not start when there is no external AC/
Inverter will not produce AC power:
1. Check that Inverter/Charger switch is in ON posi
-
tion.
2. Disconnect control cable from the Inverter/Char
-
ger.
3. Turn on machine.
4. Inverter/Charger control cable socket 2 should
have Vbatt present when the switch is ON. If not
check that there is Vbatt on the switch Yellow/Red
wire. Vbatt signal originates from Ground module
pin J1-19 then goes to harness Interlock connector
terminal 1 (Yellow/Red wire), then to switch.
LED(s) suspected to be bad:
1. Disconnect Inverter/Charger control cable from
the charger (8 position connector) and the 6 posi
-
tion connector at the chassis harness. There
should be continuity between the following:
a. 8 pos. terminal 3 to 6 pos. terminal 3
b. 8 pos. terminal 4 to 6 pos. terminal 5
c. 8 pos. terminal 5 to 6 pos. terminal 4
d. 8 pos. terminal 6 to 6 pos. terminal 6
