ArdWrknTrk Posted February 1 Share Posted February 1 Yes, as said in the texts you needed Jegs to know as you may have problems down the road, But glad it is working now. And my experience with Big Blue's 195 stat is identical to yours with a 192 stat - dead center of the gauge. Almost like that was what Ford had intended. My temp gauge sits rock solid at N. Of course my gauges are steppers (I think) At any rate they use the same senders but have some board screwed to the back of the cluster. I'm thinking this is some type of A/D converter for the instruments. Maybe this is why I can't get my Metermatch to work? Link to comment Share on other sites More sharing options...

By dialing in the middle setting I have better tracking of the gauge vs actual tank level than I remember on any of these trucks. And had I gone for two of them, one for each tank, I could have gotten the gauge even closer. But I haven't studied how the 87 and later gauges work, just that the resistance range is backwards and different to that of a Bullnose. Link to comment Share on other sites More sharing options...

As soon as I start the engine it goes brain dead and reads E I have tried over a dozen times. I am sure it has power in run & start. If I don't start the engine after setting it, it works correctly on both tanks. (I run one empty to set E and have the other full to set F) Switching back and forth results in expected behavior. I'm like a damned savant when it comes to wiring. I don't think I'm "doing it wrong". 🤷♂️ Link to comment Share on other sites More sharing options...

I don't think I'm "doing it wrong". 🤷♂️ That's strange. It works right in Run with the engine off but shows E in Run with the engine on. The only thing I can think of is that the ignition switch doesn't make the same connections when coming back to Run from Start that it does when coming into Run from Off. Have you tried jumping the relay to start the engine w/o turning the key to Start? Oh wait! Maybe I'm misunderstanding. You are setting the MeterMatch up with the key in Run, and the gauge reads correctly. But when you then turn the key to Start the gauge doesn't read correctly when the key comes back to Run. Did you hit the Save button after setting it up but before starting? When it loses power between Run & Start it probably forgets your settings.

Gary Lewis Posted February 1 Share Posted February 1 Yes, to "oh wait" Yes, I am hitting save. IDK... Maybe the Save function or button isn't working. I'd try starting the engine by jumping the relay so power doesn't go away to the MeterMatch. If the gauge reads correctly then it suggests the Save function isn't working.

I can switch back and forth, I'm metermatch knows where I set it Link to comment Share on other sites More sharing options...

I can switch back and forth, I'm metermatch knows where I set it If you turn it to Run, set it, hit Save, then turn it Off and back to Run does it remember and read right? Or are you saying that it always shows correctly in Run if the engine isn’t running? Meaning it remembers just doesn’t like the engine being on. What happens if the engine stalls? Does it read right then? Link to comment Share on other sites More sharing options...

Does it read right then? Once I start the truck it goes brain dead. It only remembers until Ithe engine is running. I can set it, turn the key off and back to run and it's fine. But as soon as I key the starter it is lobotomized. My truck doesn't stall... 😉 Link to comment Share on other sites More sharing options...

My truck doesn't stall... 😉 I was going to say "It will if you set the e-brake and come out on the clutch." But maybe in front wheel drive mode it won't? Anyway, I'm trying to figure out if it is a function of the key turning to Start & back to Run, or if it is a function of the engine actually running. Or if it is something to do with a pulse coming back from the starter motor. So starting it w/o turning the key would eliminate the ignition switch. Killing it by pulling the coil wire or some such would determine if it doesn't like the engine actually running. And bump-starting it would eliminate the starter pulse.
