IGNITION COILS:

Testing Ignition Coils:



Coil Specs (1):
Number: CTI - 118
Voltage: 12V
Primary: 1 - 1.3 ohms
Secondary: 8.5 - 9.5K ohms

Coil Specs (2):
Number: C6R - 500
Voltage: 12V
Primary: 1.2 - 1.5 ohms
Secondary: 6.5 - 8.5K ohms

Coil 1 Test Results:
Primary: 1.7 ohms
Secondary: 9.4K ohms
Earth leakage test: Infinity

Coil 2 Test Results:
Primary: 1.9 ohms
Secondary: 8.2K ohms
Earth leakage test: Infinity

Wasted Spark Coil Pack:
Coil 1 test:
Secondary: 7.07K ohms

Coil 2 test:
Secondary: 7.07K ohms

Testing Ballast Resistor:

Ballast resistor measured at 2.1 ohms

Measuring Current Draw and Voltage Drop:


Current Draw: 3.76 A
Coil calculated voltage drop: 1.7 x 3.76 = 6.392v
Coil measured voltage drop: 4.22v
Ballast resistor calculated voltage drop: 3.76 x 2.1 = 7.896v
Ballast resistor measured voltage drop: 6.96v

My calculated values did not equal my measured results because my calculated voltage drop was higher than my measured voltage drop.

Wiring up ignition systems:

Ignition module using a function generator to trigger the module.

Wasted Spark System:


Ignition module using a distributor:
