Instructions: Obtain two different ignition coils, list all coil part numbers, voltage, internal resistance specs
Coil specifications
coil 1 NO. GIC32R Coil 2 NO. CIC31
coil 1 voltage -12v Coil 2 Voltage-12v
coil 1 primary-1.7ohms Coil 2 primary-3.3ohms
coil 1 secondary-O/L Coil 2 secondary-9.75Kohms
Coil test results
Coil 1 primary- 1.7ohms Coil 2 primary-3.3 ohms
coil 1 secondary- O/L Coil 2 secondary- 9.75Kohms
Coil 1 earth leakage test- O/L Coil 2 earth leakage test- O/L
Both coils were both within spec therefore there's no need to service them.
Measuring current draw and voltage drop
Standard single tower coil
Instructions
1. wire up a ballast resistor in series with your coil primary winding values.
2. connect a ammeter in series and note the current draw.
3. measure and note the voltage drop across the ballast resistor.
4. measure and note the voltage drop across the coil primary
Current draw 2.37A
Coil calculated voltage drop 7.5v
coil measured voltage drop 7.48v
ballast resistor calculated voltage drop 4.5v
ballast resistor measured voltage drop 4.3v
My calculated results were virtually the same as my measured voltages, the small voltage difference was because of the small internal resistance in the multimeter.
Next i had to wire up a ignition module using a function generator to trigger the module.
here is the wiring diagram
Next i wired up a distributor and ignition module to trigger the module
Next i had to wire up a wasted spark system using a function generator to trigger the modules
here is the wiring diagram
