Jeep V7207293AA Ignition Coil

To check and replace the ignition coil on models except for 2000 and later inline six-cylinder models, follow these steps, start by detaching the negative battery cable. Locate the ignition coil, typically found on the right side of the engine compartment. If needed, remove the coil by unscrewing the mounting bracket bolts. If the coil is not removed, disconnect the wires from the high voltage and primary terminals of the coil. Use an ohmmeter set on the high resistance scale to perform resistance tests. Test the primary terminal to ground, which should indicate infinite resistance. Test the positive primary terminal to the negative terminal, which should indicate zero or close to zero resistance. Test the negative primary terminal to the high voltage terminal, which should not indicate infinite resistance. Replace the coil if any of these tests fail. For replacement,if not. Note that the entire assembly must be replaced if only one coil is defective. For replacement, remove the ignition coil rail assembly mounting bolts, carefully work the spark plug boots off the spark plugs, and disconnect the electrical connector from the coil rail. Then, remove the ignition coil rail assembly, and when installing the new one, make sure all spark plug boots are properly seated over the spark plugs. Secure the assembly with the mounting bolts, reconnect the electrical connector, and ensure it's locked in place.

Position the pickup coil assembly into the distributor housing.

To replace the ignition coil on 1999 and earlier models, start by detaching the cable from the negative battery terminal. Mark the wires and terminals with numbered tape, then remove the primary wires and high-tension cable from the coil. Disconnect the coil mounting bracket and remove the coil/bracket assembly. Clean the outer case and check for damage. Clean the coil primary terminals and check for corrosion. Check the coil primary resistance by attaching an ohmmeter to the positive and negative terminals. Check the coil secondary resistance by hooking one ohmmeter lead to the primary terminals and the other to the high-tension terminal. If the resistances are not as specified, replace the coil. Install the new coil and hook up the wires, then reattach the cable to the negative battery terminal.
