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.
