When I start the engine the two warning lights (oil pressure and high temp)remain on. I've checked the oil level, water level as wel as the oil filter and oil screen. Visually checked all the wiring and plug in sockets for corrosian.
The two switches you are having problems with are thermetically controlled; they can easily short out which will cause the light to stay on. First what I'd like you to do is disconnect them at the sending unit, if the lights still stay on you have a short somewhere deeper in the wiring. Most likely it will be a grounded wire. If the lights do go off you will then want to use an OHM meter to check continuity at the senders. If you get solid resistance then the sending unit is shorted out, if one remains open then isolate the other. You may have a situation that one switch is causing both to stay lit.
Let me know if this helps you out at all. Tell me if you don't have the resources to co the diagnostics as described and I'll be happy to give you a work around. We will just have to be a little creative.
Either way let me know and I'll be happy to help you resolve the issue. I'm inclined to thing your problem is a short not a heat related issue since both sending units are both indicating a problem.

Hi again and thank you for your help - its most appreciated
I followed your instructions with the following results;
With the engine off and the key on: when I remove only the water sensor wire both warning lights stay on; when I remove only the oil pressure sensor wire both lights go out.
When I check the water sensor with a ohmmeter (one probe to the sensor one probe to the motorcycle frame and set on the 20k setting) I get a reading of .01; when I do the same test to the oil sensor I get .00.
What should I replace? Thanks again for your help!
