Would a 12 V tank sender work on 6 V? Is the unit no more than a resister controlling the earth? Cheers Viking |

Viking, yes, it is just a variable resistor, so there's a possibility it would work, but I don't have a value for the 'empty' resistance of a 6 volter.  IIRC, for a 12 volter, it's 'around' 300 ohms on empty falling to zero ohms when full. ken 2CViking wrote: Would a 12 V tank sender work on 6 V?

Its not the same question, but the 6volt works without modification on the 12 volt (6v sender, 6v gauge, 12 volt battery/alternator) - Just change the lamp in the speedo cluster. |

My dipper stick works on any voltage

i can,t see it working correcty, the sender resistance and supply voltage need to be matched for the needle on the fuel guage to be correct , but i,m often wrong |

Yep, since any differences between a 12v and 6v setup are also dependent on the resistances of the electromagnetic coils in the dash instrument.  In theory, it should have been possible to make the 6v & 12v tank units with the same range of resistance, but as to whether Citroen bothered...  ken ayjay wrote: i can,t see it working correcty, the sender resistance and supply voltage need to be matched for the needle on the fuel guage to be correct , but i,m often wrong |

as u know ken, i always take accept your info  (that king pin def shattered though a shard narrowey missed the dog, no way would it have belled out-- |

Tested the 12V on the bench, showing max 190 ohms on full, slowly moving down to 0 reaching empty. |
