Westerbeke 30B 3 Temp gauge gone wild...
Ordered a thermostat a couple of weeks ago and installed to make sure it wasn't the problem. Works fine as far as I can tell.
The problem is that right from a cold engine start my temp gauge swings wildly. It will jump to off the scale, then drop to whatever the real temp. is, then back up again. Have anyone heard of this? Does this sound like a bad water temp. switch, a bad gauge, or a grounding issue to you? Whatever help you can give me would be appreciated.
Not sure if it is related or not, but my oil pressure gauge just stays peaked now as well.
