Engine water temperature gauge is down

[Pete Masterson]

Check the ground connections. This is the most common source of problems. There will be a ground at the gauge and at the sensor. If the sensor ground is to the engine block, then ensure that the ground strap between the engine and the frame is tight and free of corrosion.

99% of electrical problems of this type are ground problems. The wires are usually not likely to be damaged (outside of a few inches near the gauge or the sensor where they're exposed).

We had Branson Motor Coach take a look at it. The engine water temp gauge tested fine and will work again. The Detroit Diesel ECM still reads the engine water temp at normal temps. However, current has been lost somewhere on the gauge side between the gauge and the sensor attached to the ?/engine. I couldn't come up with a schematic showing the wire run and I'm not ready to have someone go in there blind at 110.00 p/h. Anyone have any ideas/experience here? Incidently, if you are ever in need of a full service motor coach repair while in Branson, Branson Motor Coach is very good and very fair.
