Troubleshooting Fuel Flow Issues

September 05, 2012 by Craig Peyton
  • Check EGT-ALL-FF switch setting (and connections).
  •  Check connections/crimps between instrument and fuel flow transducer. With the transducer unplugged from the FF harness, they should see around 12v +/- on the red wire and 5v on the white signal wire.
  •  Check with fuel flow tester to verify that the instrument is working and the transducer connector is getting power and ground. Call JPI Tech Support at:  800-345-4574
  • **  Do not use Teflon tape or thread sealent compound of any kind – this will void transducer warranty.** [ See “Report #503 Rev B: Date 03/14/97 under heading #2 “Initial Check Out” – line item #14. ]
