My water temp gauge has never moved a lot, but it isn't working properly now. I did remove the wires from the back, clean the contacts etc and also cleaned the connections the thermistor at the radiator end, but no change.
Today was warm and I noticed in slow town running, stopped at the lights, the needle moved to nearly half way, then fell back. If I blipped the throttle it went back up again. When running, just past the cold mark. Hoses getting hot so I know coolant is flowing.
Question is - is this likely to be the gauge or the sender? Easy enough to replace both but I could save myself a few pounds by replacing just the one part.
If I put 12v across the gauge wires and it goes up to H then can I assume it is working OK and it's the thermistor?

It may be that your whole purpose in life is simply to serve as a warning to others.

Re: Water Gauge
Macdee sent me a replacement gauge and I eventually got round to fitting it - no difference, so I replaced the temperature sender on the thermostat housing and that has done the trick.

Re: Water Gauge
I was just about to suggest that very thing.... another thing to watch for is the wire (which attaches to the sending unit) coming loose.....Stratman wrote:Macdee sent me a replacement gauge and I eventually got round to fitting it - no difference, so I replaced the temperature sender on the thermostat housing and that has done the trick.
Glad it's fixed, now it's time to ride and enjoy!
