Electrical Equipment
10.1 Alternator
The alternator fitted to the Jabiru 2200 engine is a single phase, permanently excited with a
regulator. The rotor is mounted on the flywheel with the stator mounted on the alternator
mount plate at the back of the engine. The alternator mount plate is also the mount for the
ignition coils and the vacuum pump.
Specifications
Power (Max):
120W Continuous
Note: The electrical system is Negative Earth.
10.2 Regulator
The regulator has been selected to match the voltage and current of the integral alternator.
Only Jabiru Part No. PI10652N should be used. (The regulator output voltage is 14 volts +
0.8 volt.).
Recommended wiring of regulator is positive and negative of the regulator directly to the
battery. A 20A fuse or circuit breaker may be used between the regulator & battery
10.3 Ignition
The ignition unit has dual breakerless transistorised ignition with the magnets mounted on the
flywheel and the coils mounted on the alternator mount plate.
The current from the coils flows to the distributor from where it is distributed to the spark
plugs. (See also Regulator Wiring at Page 12.)
•
The ignition is turned off by grounding the coils via the ignition switches.
•
The ignition is timed to 25
o
BTDC
•
The temperature limit for the ignition coils is 70
o
C. This should be checked by the
installer. It is recommended that pipes of 12mm dia be fitted to the top rear of each air
duct directing air onto the coils for cooling purposes.
•
Coil gaps are set at 0.25mm to 0.30mm (0.010” to 0.012”).
