Measuring Internal Resistance of an Ignition Coil

When measuring resistance, be sure that the contact
between the probes and the circuit is clean. Dirt, oil, paint,
rust or other foreign matter seriously affect resistance.
Measure resistance in the primary and secondary coils
when the coil is hot and cold.
1. Insert test leads in the input terminals shown in Figure
11.

2. Turn rotary switch to
3. Touch the probes as shown to measure resistance in
primary windings.
4. Observe display. Resistance should be less than a
few ohms.
5. Touch probes as shown to measure resistance in
secondary windings.
6. Observe display. Resistance should typically be about
10 k.
