Driving up from portsmouth last week my temp guage was rock solid at normal operating temperature 180 deg F but the LED which trips when either the manual fan overide or the temperature driven switch was glowing - though not as brightly as when the fan is operational.
I cannot figure this out as the temp guage is new and the lighting of the LED only operates dimly at sustained high speed, not at low speed urban driving.
I suspect that the temperature sender is faulty but how do I test it. Any ideas or suggestions welcomed 🤔 🤔 🤔 *confused*
