October 30: LEMON manuals on a temporary server, it is slow and having issues, download the manuals you need! Later in November we will switch back to the fast server.
Ignition Coil
Coil is designed to operate with an external ballast resistor on V8 and 6 cylinder models. Models with 4 cylinder engines have a coil designed to operate without an external resistor. When testing coil for output, include resistor tests (if coil uses a resistor). Also inspect coil for external cracks and arcing. Test coil according to coil tester instructions. Replace coil and ballast resistor, if used, that do not meet specifications.
