With the ignition on the needle on the gauge lifts to E but goes no further despite the tank being full.
I pulled the sender, wired up a new ground and hooked up a new wire from the gauge to the sender and tested the sender manually by turning it upside down and then back. The needle goes from empty to full and back to empty. Just to double check I test the resistance, 0.2 ohms right side up, 89.9 ohms upside down (the range is 0-90 ohms). So I put the sender back in the tank with the new wiring, switch on the ignition and... the needle rises to E and goes no further. So I think maybe, somehow, the floats not lifting. So I pull the sender, fill a bucket of water, dip it in, and the needle on the gauge rises and tells me I have half a tank - or less or more depending how much I submerge it. In other words, the damn thing is working. So I put it back in the tank and nothing, the gauge rises to E and stays!!! What the hell am I missing here? It works in a bucket of water but move it a foot and put it in my gas tank and nothing. John |

Cool sender, I never seen one like this. It needs to be cleaned, but I would feel terrible if I gave you bad advice which could destroy it.
If you are serious about the triple gauge, you would need a stock sender. |

If you are serious about the triple gauge, you would need a stock sender. Ha, yeah, that occurred to me this afternoon - I'll actually need to find a late 914 gauge and sender. Probably for the best, this sender is driving me insane. I scraped off some of the crud gently with a razor blade and then soaked it over night. Put it back in the car today and what do you know it worked... kind of. I placed it back in the tank hooked up to my multimeter and it rose to 13.6 ohm and stayed there. Then I hooked it up to the gauge and turned on the ignition and the needle rose up past E for the first time and just stayed there. That is, until I rebolted the gauge into the tank. And then it drop back past E, and read 2.6 ohm again on my multimeter... |
