Testing Ignition Coils (off car)

Test primary windings for IC-13 coil = 0.6Ω

Test secondary windings = 6.48KΩ

Wasted spark coil pack secondary windings :

Coil 1 = 7.09KΩ

Coil 2 = 7.99KΩ

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

Schematic :

Distributor :

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.

Schematic :

Wasted Spark :

Wire up the wasted spark ignition system using the function generator to trigger the modules.

Have the coils and spark plugs in the circuit so the spark plugs can fire.

Build a simplified ignition module :

Calculations :

Meassured Coil resistance = 3 ohms

Data sheet Transistor TIP31C  Ic max = 1amp

R1 = 5 - 0.7 = 4.3/1 = 4.3 so R1 = 470Ω

R3 = 12 - 0.5 = 11.5/4 = 2.87 so R3 = 330Ω
