T-Trophy Posted June 22, 2017 Report Share Posted June 22, 2017 Raymarine Dragonfly 7 gps/fishfinder issues If anyone has a Dragonfly 7 gps/fishfinder have you had any issues with the unit not powering on. I have checked fuse (s), plug connection , wiring . Batteries are charged. Unit does not turn on It is only one year and two months old. Thought I would see if anyone has any ideas before I call a Raymarine tech. Thank You Tim Link to comment Share on other sites More sharing options...
jimski2 Posted September 27, 2017 Report Share Posted September 27, 2017 Use a voltmeter to check the power supply wire. Where it plugs into your machine. The two power terminals must show at least ten volts as they are the shutdown point to save your machine. If you have your charger on they will show fourteen volts which then indicates a factory exchange or repair deal.Sent from my iPhone using Lake Erie United Link to comment Share on other sites More sharing options...
