Wiring up ignition systems

1. Wire up an ignition module using a function generator tDo trigger the module. Have a coil and spark plug in the circuit so the spark plug can fire.

Draw a wiring diagram of how you wired the circuit.

2. Wire up an ignition module using a distributor to trigger the module, have a coil and spark plug in the circuit so the spark plug can fire.

Draw a wiring diagram of how you wired the circuit.

4. Wire up the coil over ignition system using the function generator to trigger the module, have the coil and spark plug in the circuit so the spark plug can fire.

Build the circuit

5. Build a simplified ignition module.

Primary coil, T3, and R3 are in series circuit, the current is the same in series circuit.Vtotal=I x Rtotal. I for T3 is 500mA(from datasheet), Vtotal=12V. Rtotal=12V / 500mA = 24R. Resistance of the coil is 1.4R(CIC32R), so R3=Rtotal-Rcoil=24R-1.4R=22.6R
