Voltage too high once the alternator is online. You'll need a 12v voltage regulator to supply it. |

The one I bought years ago had some kind of resistor with it that needed wiring in for this purpose iirc ?

Sounds like what mine does but mine just works when it wants too... ? Theres no real pattern to when it decides not to show a temp i just assumed dodgy cheap guage? On 24th Oct, 2015 jonny f said:

The regulator on the fuel gauge is mecanical ( on/off) What you may need is an electronic voltage regulator.

They normally come with a zener diode regulator to make them suitable for 12V use. I think they need 5V by design. You can buy DC voltage regulators dirt cheap if you don't want to mess about with a zener diode. http://www.ebay.co.uk/itm/5x-Voltage-Regul...K7cDwCj8tRie-8w |

Looking at the gauge, I'd say 12V would be correct. It does sound as though it already has some kind of voltage regulator already, though. Is there anything on the supply cable at all? |

That looks like it should do the trick. Phil. |

They are pretty straight forward to connect up. The pin out will be easy to find on the net. One pin is ground, one is supply, one is output. I haven't checked the specs of the one in the ebay link as I was thinking you'd need 5V rather than 12V. You need to check what the supply voltage range of the chip is, as the supply voltage might not be high enough. |

Ebay description says the display needs 9-12v. Outside of that it might not work.
