STATOR

The stator supplies the system with 3 Phase AC current to 
power the electrical system 300 watts.

If the gauge and lights cut out above 3500 RPM the charge 
coils are suspect to failure. When the brown/white wire is 
disconnected it will have no continuity to ground.

IGNITION COIL 

Ignition coils provide ignition 
spark for each spark plug. 
Below are the values for each 
coil.

EXHAUST VALVE 
SOLINOID

This solenoid will open and 
close the exhaust port vacuum 
at a calibrated TPS and RPM. 
Helps provide maximum 
power across the power band. 
15

Ω from White/Yellow to 

RED on the solenoid. Fail safe 
mode will keep the valves 
closed and the unit will have 
no top end. This solenoid 

valve type a 2 way and is normally closed.
