About this guide

For diesel generators. PowerWizard lamp meanings and display messages are based on the FG Wilson operator manual, sections 5.2.5 and 5.2.11. Illustrations are simplified, not exact copies of every controller screen. Other controllers, including DCP, FG100 and Deep Sea, may use different symbols.

General guidance, not a diagnosis. Follow the manual for your exact generator and controller. JMG confirms support availability, coverage and costs.
