Pyro Gauge

[99 Stroker]

Do these sometimes go bad? ive had mine for probably about 5 months now, its unresponsive, and when i accelerate, it drops to zero, and then goes up to about 600 when i let off the gas. Any ideas?

I checked the probe, clean, all connections are clean, im stumped.

What brand of gauge is it

They usually just go dead when they break. Or get low. I would check all your grounds. Engine. gauge. battery, etc. Thermocouples work on very small voltages. Bad grounds can really mess them up. Check for cable damage. You would have to look up the voltages but you could use a milivolt voltmeter to verify if it is the probe. I think if memory serves it should be about 22 (I think) mv at 1000 degrees F . If it is ok it could be the gauge.

Sounds like a bad ground

Make sure that you have a good ground and that where the probe splits into the 2 wires, that the wire connectors aren't touching.
