Steve P Posted November 8, 2010 Share Posted November 8, 2010 Anyone know what the range of resistance should be for a Herald sender,mine has 90 ohms with about 10 quids worth of fuel but the gauge doesn't move from zero.This car has been standing for 30 years but i know the arm moves as i had the tank apart before i ran it.The temperature gauge is fine so the stabiliser must be working.Steve Link to comment Share on other sites More sharing options...
Steve Cureton Posted November 8, 2010 Share Posted November 8, 2010 No idea what the resistance should be but have you tried putting the wire to earth? If the gauge is working then this should make it read full. If not then you have a break in the connection or a faulty gauge. If it does read full then the fault lies with the sender unit.

JohnD Posted November 8, 2010 Share Posted November 8, 2010 £10 worth of fuel = about 9 litres = about a quarter full?I don't know what the resistance should be, but it should be maximum when completely empty, and 90 Ohms is the figure I've seen quoted for other Triumphs for 'Empty'.Agree with Steve's suggestion, then work with a multimeter, or just a bulb and leads, to find where the volts go.John Link to comment Share on other sites More sharing options...
Pete Lewis Posted November 8, 2010 Share Posted November 8, 2010 dont forget there are 2 senders for stabilised and non stabilised fuel gauges so resistance is different on both types of sender, Pete Link to comment Share on other sites More sharing options...

heraldcoupe Posted November 9, 2010 Share Posted November 9, 2010 The 12V unstabilised sender was only produced with 6 holes for fitting with screws.The 10V sender was available initially with the same 6-screws for fitting, later it was made with a lockring fitting.Original 12V senders always have "12V" engraved on their outside faces, however later replacements may differ. 10V senders come in many different flavours, I am uncertain if any have the voltage recorded on the outside.As we get even woolier, all 12V senders have stud terminals with nuts.Most 10V senders have a spade fitting, but, I can't be certain that the earliest ones were made this way.Good luck,Cheers,Bill.

Pete Lewis Posted November 9, 2010 Share Posted November 9, 2010 just looked at mine , wavy needle non stabilised and sender is six hole FT3331/06 (64 vitesse) suprised at the lack of availability , many sites show as NLA for H & V applicationsto make it harder both types are shown as 6 hole fixing being a posibility, but as the lock ring bayonet type was a later design you could take a guess that they are for the slow moving stabilised gauges ( but thats my guess)you can fit the 6 hole sender in a bayonet ring fitting buy cutting around the fixing holes to be small enough to fit inside the lock rim but you cant make a bayonet fit a 6 hole flange ( just some ideas ) Pete Link to comment Share on other sites More sharing options...
Casper Posted November 10, 2010 Share Posted November 10, 2010 AFAIK estates are all 6 hole?C. Link to comment Share on other sites More sharing options...

Metal Mike Posted January 20, 2011 Share Posted January 20, 2011 So what to do when i want to fit an early tank in to a mk2 vitesse. Link to comment Share on other sites More sharing options...
Pete Lewis Posted January 22, 2011 Share Posted January 22, 2011 you could fit a non stabilised fuel gauge with a non stabilised feed ..??? using the 12v 6 hole non stabilised sender leaving the temp gauge to run on the stabiliser,I guess you could add a wire wound resitor into the sender wire to re calibrate the readings by trial and error ( thinks a search in old practical radio mag) Maplins ? but unlikely to correct E 1/2 F to be all correct just a thought Pete Link to comment Share on other sites More sharing options...
