Strange behaviour from KOSO water temperature gauge
My ZX12 powered car has reliably run at between 70-85C in all conditions since I had it running earlier this year. This week however, the gauge has
started started jumping around, particularly when stationary (and warm). Typically, the gauge shows steady temperature changes, of no more than a
degree or two change in 10s. This week, the numbers have been jumping all over the place, by anywhere up to 20-30C in the same time period - today,
it registered 120C (the maximum the gauge shows), although I doubt very much if it had risen more than 10 degrees. As soon as I pull away, and build
up some revs/speed the number settles out again, at a level I am expecting (85-95C max).
I have checked the level, and it was slightly lower than ideal, but nothing to worry about. I also unscrewed the temperature sender, to check it
wasn't full of air - which it wasn't.
So, do the collective think I have a dodgy sender? Or something more sinister such as a failing water pump? Or maybe bubbles caught in the system?
Please help, as it makes me really nervous not being able to obsess over the temperature!

I had some thing like that with mine, first thing I did was boil some water and put the sender in it watch the dash to see what happens.
You could also remove the sender and fit a multimeter set to resistance and do the same thing.
Mine turned out to be faulty so easy fix.

I've had temp senders go in similarly odd ways with the temp jumping around, that would be my guess...

Thanks chaps...! Time to find KOSO spare parts then. Anyone know who sells them?
