AutoMeter pyrometer malfunction

[saburai]

Hi All,

My AutoMeter Z series EGT gauge stopped working. It's stuck at 200°. It's 9 months old and was installed correctly. Any clues? I'd like to think that the life expectancy would be a good bit longer...

Has it got power? Any other gauges having issues? You can actually test the thermocoupler separately, but sounds like a wiring issue

Thanks Wes! Everything else is functioning as it should.
You wouldn't happen to know which wire is hot? I'm thinking the red.

 

[Thewespaul]

You should have a yellow and red wire coming like this, these are coming from the thermocoupler

You must be registered for see images attach

ignore those for the time being, you should just have a ground and a hot wire other than those, I think they are the bottom two wires on the plug. If i remember right it’s a blue wire for power in.

I traced it up to the gauge disconnected the plug from the back of the gauge and probed it with a multimeter. 12v and a good ground. Plugged it back in and it seems to be working, I'll road test it in the morning. Maybe the plug was loose or a bit dirty...

fwiw
A dab of nolox (anti corrosion\transfers current) goes a LONG way here, mine did this once before I put some on.
Sounds like ya found yer issue.

If it's wired correctly give them a call. They were really helpful whenever i needed help. Also how do you have it mounted? In a cup or in a pod?

Mine did this too. They want me to ship it to them. Kinda hard to do so I left it anticipating buying a new one and it just started working again

Dash pod next to boost.

It doesn't squeeze the gauge to hold it, does it? I found the cups I had squeezed the gauge too tight and caused it to malfunction. Turns out I had the washers under the head of the screw instead of between the center spacer and band. This made them too tight.

No, it mounts with the bracket just like in the dash.

Ok, it was just a thought. Give them a call, they were very helpful with mine eventhough it was long out of warranty.

Thanks friend! As I wrote in post #5, after disconnecting it and putting it together again, it seems to be working w/of issue...
