Ignition Coil Resistance (Eclipse)
- On Mirage 1.8L, see POWER TRANSISTOR (MIRAGE) . On Eclipse 2.0L non-turbo, go to step 3). On Eclipse 2.0L turbo and 2.4L, disconnect ignition coil connector. Go to next step.
- On Eclipse 2.0L turbo, use DVOM to measure primary coil resistance between ignition coil connector terminals No. 2 and 3 (coil for cylinders No. 1 and 4) and terminals No. 1 and 3 (coil for cylinders No. 2 and 3). See Fig 2. On Eclipse 2.4L, use DVOM to measure primary coil resistance Between ignition coil terminals. Go to step 4).

- Disconnect ignition coil connector. Using DVOM, measure primary coil resistance at coil (component side) 3-pin connector. Measure between center and right terminals of connector for cylinders No. 1 and 4, and between center and left terminals of connector for cylinders No. 2 and 3.
- On all models, remove ignition wires from coil. Measure secondary coil resistance between coil towers for cylinders No. 1 and 4 and between coil towers for cylinders No. 2 and 3. Primary and secondary coil resistance should be within specification. See IGNITION COIL RESISTANCE (ECLIPSE) table. Connect coil harness connector. Connect ignition wires to coil.IGNITION COIL RESISTANCE (ECLIPSE) - Ohms @ 68°F (20°C)
