G'day guys,just got a curly one for you.l'm running a HT-HG fuel gauge & sender unit in my FC & out of the 5 or 6 fuel gauges l have all of them are broken.lts the little ceramic diode/resistor at the back of the gauge.Can anyone tell me what the hell this is & what rating/strength/resistance it is so hopefully l can solder another one in & have a working fuel gauge again. l took one in to Dick Smiths or Tandy they just looked at me like l had 2 heads! ??? Daz.
