What should the ballast resistor be for electronic ignition?
What should the ballast resistor be for electronic ignition?
The other important component of the electronic ignition system is the ballast resistor. It should be checked with an ohm meter and should have 1.2 ohms of resistance. Typically, a failure of the ballast resistor will result in the engine starting, but then dying as soon as the key is released from the start position.
When did the first ballast ignition system come out?
Ballast ignition systems were introduced in around 1970. To find out for sure, use a multimeter to check the voltage on the positive wire of the coil with the ignition on. You can test the resistance of the coil using a voltmeter and measure the Ohms (resistance) across the +’ve and –’ve terminals.
What’s the resistance of an external resisted ignition coil?
External Resisted Ignition Coils have an internal resistance of 1.5 Ohms and when combined with the Ballast Resistor you get a total resistance of 3.0 Ohms which is necessary for 12 Volt ignitions systems.
How can I tell if I have a standard or ballast coil system?

How do you replace a ballast resistor on a voltmeter?
Replace Ballast resistor. Make sure the ignition switch is off when removing or replacing the control unit connector. Disconnecting the plug from the ECM with the Ignition key ON can damage the ECM module. Turn Ignition Switch OFF. Remove wiring plug from the Control Unit (ECM). Ground negative voltmeter lead.
What is the voltage regulator for an ignition?
IGN1-16RE supplies the ballast resistor, ignition module, and voltage regulator. With key in START – make sure you have 12VDC to START-18OR and IGN2-14PK. The START-18OR wire supplies the 12VDC control signal to starter solinoid so the starter will engage.
What does it mean when ignition key is in start position?
The fact that the engine tries to start (fires) when the ignition key is in START position indicates that the Distributor, ECM and coil are working. It also means battery voltage is being applied to the input side of the Ballast resistor and ECM pin 1.
