Q:
How to remove and install ignition coils on a Ford Excursion? Posted by Customer
A:
Disconnect the cable(s) from the negative battery terminal(s). Disconnect the ignition coil electrical connector(s) from each individual coil. Use tape and mark each electrical connector with the correct cylinder number to prevent mix-ups during reassembly, if necessary. Remove the bolt securing the ignition coil, then pull the coil from the cylinder head. Note: 2006 and later models have individual coils for each spark plug. The coils are mounted to the top of the valve covers. Installation is the reverse of the removal procedure with the following additions: Prior to installing the coil, coat the entire interior of the rubber boot with silicone dielectric compound. Connect each coil electrical connector to its correct coil and make sure they are tight and secure.

Q:
How can you check the coil primary and secondary resistance in breaker points type ignition systems for the 1982 Lincoln Town Car? Posted by Customer
A:
Use an ohmmeter to check the coil primary resistance and compare it to the specifications. Do the same for the coil secondary resistance. If the resistances are not as specified, replace the coil. Keep all coil terminals and wire leads clean, tight, and dry.
