    84 k5 Stock fuel Guage stuck on 1/4 tank???

    I GOT IT FIGURED OUT! it's bad magnets in my stock guage. Even tho it tested right in all the ways you could check the guage and resistor on the back it still would not read right. New Amazon cheapo guage I hooked up worked like a champ!! Now to find a parts guage on Facebook marketplace before...

    84 k5 Stock fuel Guage stuck on 1/4 tank???

    Checked all the grounds, all look good. Checked ground and positive again on gauge cluster and I have both good ground all around and 12v power. Tested sending unit again in ohm and read 60-70 ohm (would be right for the 3/4 tank it has) and also did ohm test on pin behind the guage that reads...

    84 k5 Stock fuel Guage stuck on 1/4 tank???

    The new sending unit (even tho old one was fine) came with entire new ground wire crimped on. I cleaned frame well when attaching. Shows I get good ground there too when I test sending unit with ohm and test light. And every thing else in truck and dash works well, should I still check engine to...

    84 k5 Stock fuel Guage stuck on 1/4 tank???

    Im pretty sure i have good ground and power on cluster and guage. Should I try it with out resistor? Or maybe just try to install a aftermarket universal guage with everything built in?

    I actually took the resistor off the back of the guage and cleaned it nice and well. And guage reads 90ohms when tested alone should mean resistor is good right?, it pegs full when sending wire is disconnected. That all signs of a solid guage right?

    84 k5 Stock fuel Guage stuck on 1/4 tank???

    I have ran a separate ground wire to it to triple check the ground on guage to dash.... isn't it odd it still reads 1/4 even when ground from tank is disconnected?

    84' K10 Fuel Gauge Issue

    I am having a similar issues my self. I posted a thread also trying to figure it out! I read 65 ohm at new fuel sending unit (about 3/4 tank) but behind guage I'll only ready about 7 ohm (1/4 tank) with key off. And my sending wire seems to be fine (no shorts or pinches) and about everything...

    84 k5 Stock fuel Guage stuck on 1/4 tank???

    If I keep ground hooked up, and ground out the sender wire it does drop to E. Put sending wire back on the post and right back to 1/4 tank. OH YEAH! And According to how much gas I seen in it (3/4 tank) when i had sending unit out and what the sending unit reads in ohms ( about 65ohm) which...

    84 k5 Stock fuel Guage stuck on 1/4 tank???

    I just went out and double checked. If I take groun wire loose from sending unit to frame it still reads 1/4. If I take the red wire off fuel sending unit it pegs full. So even with ground wire not attached to sending unit it still reading 1/4. Even if I move it with my finger it goes right back...
