3100W Inverter Computer Module Replacement

Updated 4 months ago by Juan Velez

This covers all Champion 3100W Inverter Models.

Read instructions carefully and completely before performing service.
  1. Remove the three screws along the top handle on the air cleaner side of the inverter. Also, remove the two screws on the side of the panel and the two 10 mm bolts at the bottom of the side panel.
  2. You can now sing the panel open to the left. This will expose the control unit. Remove the two 7 mm bolts and plates holding the computer module in place. Also, remove the bolt and nut holding the DC output module. Slide the control unit straight up and out of its holder. 
  3. Begin disconnecting the control unit's wire harnesses. You can now discard the old module and install the replacement module. Reverse previous steps to complete the service.
