Is it newly installed? Are the wires backwards? Sensor clean or cable properly adjusted.?

Engine warning light , battery light, warning light , rev counter , speedo and temp gauge going on/off intermitantly and speedo not working on digital screen on ford focus can you help. the battery is new...

My 04 Ford Focus the battery light keeps coming on & going off, have fitted a new alternator belt but it didn't solve the problem. The battery connections are good. Also the rev counter, speedo & mileage clock keep going haywire when the battery light is on. Do you think it is the alternator? Or is it some other common problem?

I have a thunderace and the rev counter keeps jumping from 0 t0 7000 revs

7000 rpm is a self diagnostic code that either your exup valve is not being detected or the valve is locked up and not moving. If you put a header on your bike and took over the exup valve servo motor, you are going to have to put it back on. It also changes the mapping of the ECU and will not let it rev to redline when the Exup servo motor is missing.

Yamaha 2001 r1 been stood for 2 yrs ;got back on road ;rev needle keeps going from 0 rpm~~7000rpm all the time;bikes runs but must of lost half the power of the bike ????

Hi There,
Got this from my copy of the Yamaha workshop manual for this model

The YZF-R1 features a self-diagnosing system for the following circuits:
1. throttle position sensor
3. fuel level indicator light
if any of these circuits are defective their respective condition codes will be displayed on the tachometer when the main switch is set to "ON" (irrespective of whether the engine is running or not)

1. throttle position sensor a) Disconnected b) Short-circuit c) Locked 0 - 3,000rpm
2. EXUP a) Improper connection b) Short-circuit c) Servomotor is locked 0 - 7,000rpm
3. Fuel level indicator light a) Improper connection 0 - 8,000rpm

It looks like you have a problem with the EXUP Valve on yours, probably seized or maybe cables not moving freely
Hope this Helps
