The temp gauge has stopped registering. Can anyone suggest the best way to test it before buying a new one. has anyone an idea what resistor I'd need
between the sensor connector on the head and ground to make the gauge register to check it's OK and confirm the sender is at fault - wiring is ok I've
buzzed that out.

Adrian, just put a 12V bulb between the live feed and earth, the lamp should light up regardless of how full the tank is although its brighteness will
vary accordingly - I suspect that resistance is at its minimum when the tank is full therefore the fuller the tank the brighter the lamp will be. If
the lamp lights up then you know the sender is working fine and the fault nmust lie with the gauge. Also, don't forget to check the earth is grounded
okay, no point checking the live feed if it's the earth that's at fault.
