Ignition Coil: Testing and Inspection

Checking Primary Resistance:

- Disconnect ignition coil No. 1 electrical connector.
- Measure resistance across primary terminals.

Should be 0.40 - 0.50 ohms

Checking Secondary Resistance:

- Remove coil high tension wire.
- Measure resistance between high voltage terminal and indicated connector terminal.

Should be 10.0 - 14.0k ohms

- Replace coil if results are not achieved.
- Repeat test on ignition coil No.2.
