Reply to ""Adjusting" water temp gauge"

Bob,

You shouldn't need a resistor with the 230* gauge. I would recommend that you add a separate ground wire from the temp gauge to a good ground point. This will eliminate fluctuating gauge readings that are caused by the original wiring's daisy chain configuration.

If you need to replace the temp sender, the Echlin TS6628 from NAPA should be a good match for your gauge.
