3-15
48V Battery Pack (SN C170000330 to Present)
A - Remote control display is OFF
1.
With the key switch in ON position, open the
main board electric box, and check the LED on
the main board.
If ON go to step 2
If OFF go to step 3
2.
LED on the main board are ON
If the LED are ON then the main board is also ON,
so the remote control failure is not because of
the Lithium system. Refer the wiring diagram to
check the remote control feed.
3.
LED on the main board are OFF
Check the 12V Lead-acid battery; it supplies
power to all the boards during the ignition, so if
it is not OK, the machine will remain off.
Check the voltage on the 12V switch under the
key switch. IF red wire to the ground has 12 Volt,
go to step 4, if not go to step 5.
4.
Red wire has 12 Volt
Check the 12 Volt switch under the key switch,
and check the connection of the wire OR0400 (or
1/12), from the key switch to the pin B1 in the
master board.
5.
Red wire does not have 12 Volt
Check fuse F6, then check the supply from 12V
Lead-acid battery to fuse F6 (= Lead-acid battery
+ feed con R1 + 2 ways connector).
B - Battery package level is “zero” even after the
charge
Check the value in the INPUT menu, press button
number 6 “service”, then press 1 “input”, then 1
“previous”. Press button number 9 “Esc” to go
back.
If external electrical power is available, connect
the 110-220V power cable, and check the bat-
tery charger light after two minutes;
If the battery charger light flashes red, go to step
6.
If the battery charger light flashes green/red, go
to step 7.
6.
Connect the power cable, the battery charger
light is red after two minutes.
The system works correctly. Keep the power
cable connected until the light on the battery
charger will flash yellow. Test the machine again,
if the problem remains, go to step 9.
7.
Connect the power cable, the battery charger
light flashes red/green after two minutes.
This condition indicates the battery charger
does not find the 48 Volt battery package. Check
fuse F1, then check fuse F3, then check the wire
“123” connected from the pin no. 5 of the “6
ways BC connector” to the wire “111” pin no. 2 of
the “5 ways BMS connector” of the BMS. Check
