- 8 FLASHINGS: either the power fuse or the
power relay is faulty
Check that the 30A power fuse (pos. 4 on the
fuse-holder) from + battery till the traction
board is OK and that the battery and motor
wires are properly connected
If necessary, replace the traction board.
- 9 FLASHINGS: under tension
Battery tension lower than 19V.
- 10 FLASHINGS: overcurrent
Battery tension higher than 45V.
- 11 FLASHINGS: amperometric protection of
the traction motor: the motor has worked for
more than 10 seconds above the maximum
nominal current value (15 A)
Verify that the differential spins freely.
Check with an ammeter the motor consumption.
For the correct consumption values refer to the
technical chart.
- 13 FLASHINGS: temporary power supply
interruption
Attention! If 13 flashes appear, the operator
should first ensure that at least 3-4 seconds have
passed between turning off the machine (key in
position 0) and turning on the machine (key in
position 1). This is the time required for the
traction electronic card to activate. Otherwise 13
flashes are generated.
If the problem persists, it could be a bad
electrical contact issue: check that in the ignition
switch, fuses and the 16 pole connector of the
chopper there isn’t any intermittent contact. If
the problem persists again replace the chopper
- 14 FLASHINGS: failed data reading
Remove the key and put the service switch in O
position
If necessary, replace the traction board.
