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
- Remove primary and secondary leads from ignition coil. Using an ohmmeter, check resistance between primary terminals "A" and "D" of ignition coil. See Fig 1
. Resistance should be .3-.4 ohms at room temperature. Check resistance between terminals "B" and "D" of ignition coil (tachometer circuit). Resistance should be about 2090-2310 ohms at room temperature.
- Check secondary resistance between terminal "A" and secondary output terminal (coil tower). See IGNITION COIL RESISTANCE
table.
- Check for continuity between terminals "A" and "C". Continuity should exist. If readings are not within specification, replace coil.
