Testing the 2000-Watt Inverter Ignition Coil (Cubed)

Updated by Juan Velez

This covers all Champion Power Equipment 2000-watt cubed inverter models.

Read instructions carefully and completely before performing service.

  • To reduce the risk of injury, user must read and understand the operator’s manual before using this product.
  • DO NOT make any adjustments to the generator without first stopping the engine and disconnecting the spark plug wire.
  • Burns from hot parts — let the engine cool completely before touching hot parts.
  • Injury from moving parts
  • To reduce the possibility of fire or explosion, be careful when working around gasoline. Keep cigarettes, sparks and flames away from all fuel‐related parts.
  1. On the inverter ignition coil, a simple test can be conducted by connecting a 12V battery to the two leads coming out of the ignition coil. They are blue (positive) and green/yellow (ground and negative).
  2. Hook the battery to each appropriate lead and then make and break the negative connection to force a discharge spark from the end of the plug wire as you hold the wire near the engine case (1/4 inch air gap).
  3. If you see a spark during each make break cycle, then the coil is just fine, provided you see a nice and bright blue/white spark. A yellow or orange spark is weak and coil will need to be replaced. A weak spark will not ignite the compressed fuel.
  4. If the spark test passes, then you will most likely need to replace the ignition assembly. This is the module you can see on the front panel of the inverter with the three LED lights (green, red, and yellow).
