Does anyone know how to test a Chrysler ignition module? This is the late '80s type that has a sealed module and a five pin connector. My engine will turn over strong, but won't start. There is no spark visible at any spark plugs. I have 12 volts at the ballast resistor and across the ignition switch, so all indications are that it's the module, but before I buy a new one, I'd like to test it.
