1982 Chrysler ImperialFACTORY OEM SERVICE PROCEDURE

Ignition System Test

  1. Hold secondary coil wire 3/16" from good ground and crank engine. If a good spark is seen, repair cap, rotor, or secondary wires. If no spark is seen, go to next step.
  2. Remove 10-pin connector from CCC and connect ohmmeter across pins 5 and 9 in connector. If resistance is between 150-900 ohms, pick-up coil is okay. Check resistance between pin 9 and ground and pin 5 and ground. If resistance is very high, no short exists. If resistance is low, check for short between pick-up coil and computer.
  3. If resistance of pick-up coil is zero, coil is shorted or grounded. Check at distributor connector for continuity between either connector wire and ground. If grounded, replace coil and attempt restart. If coil is not grounded, go to step  5).
  4. If resistance at pick-up coil is too high, check again across the 2 terminals in the distributor connector. If resistance is now between 150-900 ohms, repair circuit to computer. If not, the harness is okay and the pick-up coil must be replaced. Attempt restart.
  5. Voltage at coil positive terminal (during cranking) should be 9 volts or more. If not, check voltage at starter relay "BAL" terminal while cranking. If voltage is 9 volts or more, repair circuit to coil. If not, check battery and/or replace starter relay.
  6. If voltage at coil terminal is 9 volts or more and engine will not start, disconnect 10-pin connector at computer and connect voltmeter between pin 1 in connector and ground. While cranking engine, voltage should be 9 volts or more. If not, repair wiring harness and attempt restart. If so, go to next step.
  7. Connect ohmmeter between pin 10 and ground. If continuity is not shown, repair ground connection to pin 10. If continuity is shown, disconnect ASD module and repeat step  1. If a good spark is shown, replace ASD module. If not, replace CCC.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
