pyro not working

[65sixbanger]

Ok here in the last few weeks my pyro goes up and down very fast and sometimes wont even register a temperature. Do yall think this is the sender going bad? I tried the factory banks gauge as well as an isspro and they both do the same thing so that makes me think its the sender. connections are tight. Also, if it is the sender, are they universal for the most part?

My ISSPRO's are real sensative at the amplifier boxes, I have to make sure they are secured tight, or my gauges jump up and down a lot. Look for loose connection?

sounds like the probe is headed south - replace it.

ok thanks,

Justin I have mechanical gauges and I dont know if I have an amplifier box....

Mine is real slow to react, I think that will be the next project on my list.

Well if you have the mechanical gauges than what I said is void. The ISSPRO EV gauges use an amplifier box in between the sender and gauge.

Hey check with your local Caterpillar dealer, they were able to source the sender only(no wires or gauges) for me for only 43 bucks or so. Yes they are more or less universal you just have to keep like parts with like. Almost all of us and almost all gas/diesel pyros use Type K thermocouples and a 0-1600 or 0-1800 range or similar. The only other thing to be concerned with is to make sure you use the correct hole size for the probe, it's either 1/4 or 1/8 inch and the correct terminal type to what you already have. Pyro wires are very sensitive and don't like a lot of cutting and splicing so you must keep that to an absolute minimum.
