Alistair Posted March 8, 2016 Share Posted March 8, 2016 How would I find out what Ohms range my fuel gauge has? Setup a potentiometer with volts gauge, set it to an arbitrary figure like 90 Ohms full, then connect to 12v with the potentiometer on the gauge and see where the needle reads at? Need to fit a sender to my fuel cell but they seem to have different Ohm amounts. If the stock ke20 gauge is different to what is available in the senders am I stuck with having to buy an aftermarket fuel gauge with the matching ohms?

Frosty Posted March 8, 2016 Share Posted March 8, 2016 Once you have all the bits, Sender for tank and the range of movement worked out. Then drop in into a good Auto sparky or Instrument tech to re calibrate the KE gauge. Quote Link to comment Share on other sites More sharing options...
mjrstar Posted March 8, 2016 Share Posted March 8, 2016 Nah you can adjust by adding the appropriate resistor. Unless you have a -ve vs +ve slope. Then it gets a bit tough. If you have access to a decade box or variable resistor and a cheap multi meter you can draw up a table of resistance vs sender position and gauge position. 1 Quote Link to comment Share on other sites More sharing options...
Ned Posted March 8, 2016 Share Posted March 8, 2016 What's the standard one, and what's available? Quote Link to comment Share on other sites More sharing options...
Alistair Posted March 8, 2016 Author Share Posted March 8, 2016 What's the standard one, and what's available? Do you mean gauge or sender? There is no sender in the tank, needs to be cut into it and fitted. The fuel gauge is stock KE20. Quote Link to comment Share on other sites More sharing options...
flyingbrick Posted March 9, 2016 Share Posted March 9, 2016 I recently set one up on a custom tank...the sender was from these guys http://shop.classicinstruments.com/fuel-sending-units and was the arm and float type. SUPER easy to set up/calibrate and available in different ohms. Highly recommended Quote Link to comment Share on other sites More sharing options...
