Inaccurate guage?

[arcflash]

Autometer Procomp Ultralite Pyrometer reads 120* when truck turned off. Turn key on, still reads 120*. Shouldnt the gauge zero out once the key is turned on, I know my buddies Isspro pyro does.

Does it still read EGT when you're driving? I don't think the gauge will zero out because the circuit for the thermocoupler isn't hooked up to a 12v source like your factory gauges.

It should do a full sweep when turned on, then back to zero. That's the way my DiProcols are

Do you have a fairly powerful CB radio in the truck? When I got my gauges, mine did the same thing as yours. Kash at GOS had me send it back to him, and he sent one out that was an updated gauge. Apparantly this was an issue(at least with DiProcol), and they did something to the newer ones so that CB's did not interfere with them.

I know this sounds out there, but it's no joke. That's what happened to me.

Im gonna give autometer a call once I find the reciept and see what the have to say. Its about 270* at idle atm, about 800* at 70 mph no load.

Wow thats wild right there. Who would have thought!

I had to go out and check my Autometer gauges. With the key off, the Pyrometer will be all the way counterclockwise (zeroed). With the key on, and waiting for the "wait to start" light to go off, it will read the current temperature in the manifold (or whereever you have the probe installed.) As the starter cranks the engine, the needle drops fully counterclockwise until the engine starts. Then it reads the EGTs, again. Hope this helps.

I'm not sure about the specific Auto Meter model, but if they are standard air core (rather than stepper motor) gauges, they will behave like luckydog's. If they are stepper motor, then they will do the "homing" step mentioned above.

where did yall wire you gauges to? i just got mine and i need a good power source.. got pics?

[lcducote]

sorry for the hijack...

I wired mine in this past weekend, Ultra-lite, I used a doc from IPT diesel, and diesel manor, both have very nice write ups and nice pictures. Mine sit at about 80 with key off, and jump to 120 when key is turned on, and back to 80 when cranking and back to 120 and climb when motor is started. I run about 570-600 at 70 MPH 530-550ish at 60. I would be interested to find out why they don't zero out with key off. Just bought mine last week.
