WIRING UP IGNITION SYSTEMS


Warning: Ignition coils create high voltage. It can be dangerous, so avoid getting
too close to ignition parts when engine is running. Make your connections when the
engine is off, and then keep your distance when the engine is running. Even some
primary voltage is high enough to stop a “Pacemaker”.
Warning #2: Don’t ground a coil for more than a few milliseconds or more than 50%
duty cycle. You can overheat the transistor or melt the inside of the coil. They will go bad!

Have a coil and spark plug in the circuit so the spark plug can fire
Check with your tutor that you have done it correctly

.
C = Coil [connect to coil negative side]                                                                               
EXT = connect into negative post of power supply [ earth ]
B  =  connect to positive post of power supply [+ side ]
T  = connect to red wire from function generator
F  =  Feedback [ leave it free ]


Draw a wiring diagram of how you wired the circuit




Wire up an ignition module using a distributor to trigger the module.
