PROBLEM CAUSE REMEDY
4. The pilot lamp is flashing
with the key in the
«START» position and the
starter motor does not
turn
Starting not permitted [see summary
logic table 7.2] After checking that the conditions are met,
check all the microswitches [see 7.3] and the
relative wiring.
5. The starter motor turns
but the engine does not
start
No fuel flow Check the leads for the carburettor solenoid
valve opening control (if provided) or check
the fuel stopcock and filter.
6. The starter motor contin-
ues to turn after engine
has started, and does not
stop when the key is
removed
Mechanical difficulties with the con-
tact breakers of the starter relay Replace the starter relay.
7. The starter motor operates
as soon as the key is in the
«ON» position, and can be
turned off only by removing
the key (pilot lamp on)
Fault in the card Replace the card
Starter block operating faults Replace the block
8. The pilot lamp does not
come on when the key is
in the «ON» position but
the machine works
Fault in the electronic circuit or in the
signalling LED Replace the card ( NOTE: You can finish the
work in any case, but you need to replace
the card or signalling LED as soon as possi-
ble)
9. The pilot lamp becomes
weak after several hours’
work
Insufficient charge Check that the charging cable has not
detached
10. The engine stops while in
use for reasons not due
to the safety devices cut-
ting in
The safety devices have cut in or are
faulty Check the microswitch’s operation and the
relevant wiring [see 7.3 and 7.7]
Accidental detaching of an electrical
wire Check all wiring
Starting of engine not permitted [see
summary logic table 7.2] After checking that the conditions are met,
check all the microswitches [see 7.3] and the
relative wiring.
Check that there are no current leakages
caused by cables with damaged insulation
Check that the regulator is working properly
[see 7.8]
Starter works erratically for mechani-
cal or electrical reasons taking exces-
sive current and causing binding of
relay contacts Check the starter motor
Impaired starter system Check that spark plug caps are positioned
correctly
Check that the spark plug electrodes are
clean and have the correct gap.
Malfunction in the electronic card Try replacing the card with one that is known
to work
Charger fuse blown Replace fuse (25 A) and check the recharge
circuit [see 7.8]
