Ignition Coil Resistance (Eclipse)

  1. 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.
  2. 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).

  3. 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.
  4. 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.
