and to earth on the engine (5). Activate the
starter and see in the instrument if the spark
jumps.
3 If the test has a positive result, clean the elec-
trodes (2) with compressed air and adjust the
distance to 0.6-0.8 mm. Remount the spark
plug and tighten it to the specified levels.
Otherwise, check the system parts as described
in point “B”.
B) Adjusting the air gap and checking the coil
11 Remove the starting system [ 6.2.A].
12 Remove the tank [
6.1.A].
13 Remove the conveyor (10).
14 Make sure that the earth cable faston (11) of the
coil (12) is not oxidized; if it is, disconnect, clean
and remount it, spraying it with a special antiox-
idant.
15 Make sure that the earth cable (11) is intact. The
black spark plug cable (13) should not have any
cracks or signs of deterioration or burns which
reduce its efficiency and insulation level.
16 Loosen the screw (14) and the stud bolt (15)
securing the coil (12), release the brake manual-
ly and rotate the flywheel (16) until the magnet-
ic inserts are lined up with the poles of the coil
core (12).
17 Insert a 0.35 mm thickness gauge (17) between
the flywheel (16) and the coil poles. Push the
coil until the poles come in contact with the
thickness gauge and secure screw (14) and stud
bolt (15). Tighten the screws remembering that
the air gap must be between 0.25 and 0.40 mm.
NOTE
An accurate inspection of the efficiency of a coil can
only be carried out in a laboratory equipped with a
oscilloscope. To make a brief check, proceed as fol-
lows:
18 Disconnect the faston of the black earth cable
(11) and reposition the upper conveyor to acti-
vate the starter.
