48V Battery Pack (Prior to SN C170000330)
Some potential concerns and possible corrective actions
are listed below for 48 Volt battery pack.
A - Remote control display is always 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. If
Lead-acid 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.

Check the 12 Volt switch under the key switch,
and check the connection of the wire 1/12, from
the key switch to the pin B1 in the master board.

Check fuse F6, then check the supply from 12V
Lead-acid battery to fuse F6 (= ead-acid battery
+ feed connector + R1 + 2 ways connector).
