HV coil secondary resistance value:
1) Disconnect the HV cable from the spark plug
and measure the resistance between the spark
plug cap and the HV coil negative terminal.
2)Disconnect the spark plug cap from the HV cable
and measure the resistance between the HV cable
end and the HV coil negative terminal (see figure).
3) Measure the resistance between the 2 ends of
the spark plug cap.
Characteristic
HV coil secondary resistance value with spark
plug cap
~ 8.4 kΩ
HV coil secondary resistance value:
~ 3.4 kΩ
Spark plug cap resistance value
~ 5 kΩ
Battery recharge circuit
The charging circuit consists of three-phase alternator and a permanent magneto flywheel.
The generator is directly connected to the voltage regulator.
This, in its turn, is connected directly to the ground and the battery positive terminal passing through
the 30A protective fuse.
The three-phase alternator provides good recharge power and at low revs a good compromise is ach-
ieved between generated power and idle stability.
Remote controls check
To check the operation of a solenoid:
1) Check that, given regular conditions, there is no
continuity between terminals 87 and 30.
2) Apply a 12V voltage to power terminals 86 and
85 of the solenoid.
3) With the solenoid fed, check that there is con-
tinuity between terminals 87 and 30.
4) If these conditions are not met, the solenoid is
surely damaged and, therefore, it should be re-
placed.
