3.10  WARNINGS ON THE ELECTRICAL SYSTEM 

 

  We are here listing the main warnings on the electrical system. 
  Please keep this in mind during the whole life of the engine. 
  
          WARNING: 

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 
KEY  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 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 connector 
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 H.T. coil  is connected to the engine with the grounding cable. The eyelet connector 
must be directly in contact with the laminations pack on the H.T. coil. 

 

8)

 

Never use  H.T. coils different than the original coil on the engine. Use of 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 electrical system is protected against battery polarity reversal. When reversing the 
connectors on the battery, the protection circuit activates the fuse as soon as the key is 
on KEY or RUN 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,  is  guaranteed  by  the 
electrical  system.  A  few  minutes  of  engine  in  operation  are  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.
