ISSPRO problems?

I dont know if this is in the right area but here it goes.

My EGT gauge started acting funny the other day, it would randomly drop down to 100 degree while I was driving. I looked under the dash and found one wire was loose. It was the positive wire to one of the control boxes.

I hooked it up good and tight thinking it would fix it but it didnt.

What else could it be. Sometimes it seems accurate and most of the time its bouncing between 100 and 600 degrees. Could it be the amplification box went bad? is there a fuse? could it be a bad ground? or EGT probe is bad?

Thanks in advance

yeh it was to one of the control boxes. ISSPRO gauges have 2 control boxes I believe.

Well i've never used that brand, but I do know if a power wire gets a loose connection and shorts out a few times. Sometimes it fries a few things. Does it always read something or does it shut off sometimes?

Its hard to tell it always lights up but the needle sometimes drops all the way down.

There is an amplification box for the EGT sensor that might be it. Maybe the signal it weak or something. I just need to rewire the whole thing one day. I hate using thinks a previous owner installed.

The guy used house wire some 12ga crap, so I need to install something smaller and more for a automobile.

yeh thats what I was thinking. There is about 8 ground wires for the whole system I am sure one of those could have come loose.

oh well it would be nice to clean up some more of the previous owner crap. I already took out at least 100ft of wires from in the engine and under the dash. dont even ask why, he was splicing in to the wiring harness all over. I had to get a brand new engine harness and repair the underdash harness.
