Customer Question

Bike 2005 FLHTCUI
Speedometer, Tach, Volt Metre, Fuel, Air Temp and Oil Pressure gauges do not function. The bike starts and the gauges are lit and 'slightly' move when fuel pump pressures up. The 'Red Key' stays on for 4 seconds, goes off for 4 seconds then stays on. Check engine light does not come on at all through start-up. Unable to retrieve any Trouble Codes. Bike does start and run with Headlights, taillight and signal lights working normal. Please help. Walter

- the red key is a function of the turn signal module. it indicates a failure in the module.

- the "instruments" are powered off the INSTRUMENT fuse. check the fuse block, left side, behind the side cover.

let me know if you need more help.
