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 Resistance

Disconnect electrical connector and ignition coil wire from ignition coil. Using a DVOM, measure primary and secondary resistance. Primary coil resistance should be 1.35-1.65 at 68°F (20°C). Secondary coil resistance should be 22,100-29,900 at 68°F (20°C). Replace ignition coil if readings are not within specification.
