Re: Fuel light query.
Mine flashes first and then goes solid. With my consumption (40-45mpg if lucky) its about 30 mile range in total with the last 10 on solid.

Re: Fuel light query.
Had similar trouble myself.
The fuel sensor has two thermistors (ntc) held at fixed heights in the tank. The current supplied to the thermistors causes them to warm up and reduce resistance, however, the fuel disipates the heat which keeps resistance high. Once the fuel level drops below the top thermistor, it heats up and drops resistance to 0 which triggers the flashing light on the dashboard. After the fuel drop below the second thermistor the light goes solid (note 1). However (and this is the part that caught me out) if the thermistors have degraded/broken, then they won't drop resistance enough to trigger the lights on their own, but together they can trigger the flashing light. You think you have 30ish miles to go, the bike cuts out after 10 The solution is to either replace the sensor unit, or to attempt a repair (note 2). On one of the Goldwing forums in America, there is a chap (http://www.duaneduncan.com/low%20fuel%20sensor.html, and also http://www.electronicspoint.com/ther...k-t123318.html) who has found that 1kOhm NTC thermistors will be adequate to replace the stock ones. I haven't tried this yet, but will do when I can get together an electrical parts order that comes to more then the postage costs! Note 1: it doesn't matter which sensor is uncovered first, the light will flash with one thermistor uncovered then go steady with two (ooer).The test procedure in the Suzuki service manual involves dunking the sensor "upside down" into a container of fuel Note 2: only attempt a repair if you are competent with electronics, as electricity and fuel can go bang (albeit highly unlikely in this application) and I have no desire to see you toast your bike

Re: Fuel light query.
Cheers guys, so I think the concensus is tht it's meant to flash then go solid. However mine didn't, I pushed it and pushed it then after 15 miles with the light flashing it cut out. I mite have a spare sensor if not then I'm an apprentice at bae I'm sure my tutor could help me out.
Thank you Scott |
