Temp gauge resistors so I can test the gauge HX HZ

[damienengland]

perfect, that confirms that I have the correct sender fitted [52 ohm reading warm] thanks.
does anyone know what resistor size I need for bridging across the wire [to the sender] and negative?

If you want to test the gauge with a resistor, you will need either some fixed value resistors in the range of 73 - 10 ohms or a potentiometer that has the same range available. For a quick check, short the dark green wire connected to your temp sender to earth and then briefly turn the ignition on. Your temp gauge should go to full scale deflection.

your on the money l had this happen to me now all good runs at quarter temp

Ta, will try that tomorrow. otherwise the gauge goes back to the shop
