3.11 WARNINGS ON THE ELECTRICAL SYSTEM
We are listing the main warnings on the electrical system.
Please keep this in mind during the whole life of the engine
ATTENTION:
If these prescriptions are not followed the electrical system and the engine
could be damaged beyond repair. No obligation of IAME exists in this case.
1) Please turn the key to STOP position every time the engine is stopped. If the key
is left in RUN position for a long time, even if the engine is stopped, the battery
would be discharged completely.
2) Never disconnect the ground cables with eyelets (ground cables) when the engine
is in operation.
3) Disconnecting the battery when the engine is in operation DOES NOT increase the
engine performance. Vice versa, the ignition advance could become very irregular
at low RPM thus reducing the performance.
4) To fasten the eyelet terminal (groundings) of the wiring harness always use flat or
open washers. Never use tab washers.
5) When disconnecting the connectors, always press the fixing tongues. Always pull
the connectors to disconnect. NEVER PULL THE CABLES.
6) The electronic box and the starting relay must always be installed with their
connectors towards the bottom to avoid back water, dampness or dirt in the
connector body.
7) Always correctly fix the H.T. coil with both screws, make sure that the laminations
pack on the H.T. coil is connected to the engine with the grounding cable (copper
cable or screws). The eyelet connector must be directly in contact with the
lamination pack on the H.T. coil.
8) Never use H.T. coils different than the original coil on the engine. Use of a different
coil may cause damages to the electronic box.
9) The digital assembly needs use of a resistive spark plug cap or spark plug. The
resistor value must be equal or higher than 5 Kohm. Avoid use of resistive H.T.
cables.
10) The electric system is protected against the battery polarity reversal. When
reversing the connectors on the battery, the protection circuit activates the
fuse as soon as the key is in RUN o START position. The fuse must then be
replaced.
11) Replace the fuse after having disconnected both terminals on the battery.
Only use 5A strip fuse. Use of fuses with higher amperage might damage the
electronic box whenever the battery polarity is reversed.
12) Only use sealed lead type batteries as specified by IAME. Only use 12V. batteries.
13) Always disconnect the battery from the electrical system when recharging the
battery with an external battery charger, otherwise the internal voltage regulator
could be damaged.
14) DO NOT connect batteries in parallel; this might cause explosions and damages to
the operator. The recharge of the battery, in normal conditions (battery charged,
proper starting, etc...) is guaranteed by the electrical system. A few minutes of
engine in operation is sufficient to recover the energy lost when starting the
engine.
15) In case the battery must feed other users (tachometer telemetry, etc...),first
contact IAME to check the recharge capacity of the system.
16) Modifications, interventions and additions to the original electric system might
cause malfunctions. No obligation of IAME exists in this case.
