[V8] So what is bad/going bad here - Temp gauge pegged on overheat?

[S_Matus]

Ingo - 

I have a pegged Oil Pressure and intermittent Fuel gauge with my IC. I think this is bad connections, because differing humidity levels will function properly.  I'm going to go back in for a second time to try to correct the ills I created from my first attempt to fix it.  I'll try to do some investigations with my ohm meter to see if I can shed some light on these gauge issues.  It is just so damn difficult to R&I the IC that this information is not knowm because of the labor involved.

I'll post any findings I have in the near future.

Scott.

So I couldn't figure out what was going on with the temp gauge stuck  
on overheat.  Once the black connector was removed the gauge would  
return to the normal min/off position.  This connector only supplies  
current to the board, for the most part, specifically circuits 30,31  
and 15.  Anyhow, in the interim, I've replaced the IC with the one  
from my project, er, parts car and everything seems to work except I  
now have that annoying PRD321 display - annoying when you have a  
manual tranny ;-)  I'm sure I can disable that without much trouble.   
Of course, this IC isn't perfect -- 720 miles to empty?  I don't  
think so!

Ideas regarding the bad circuit/tracde solder joint on the original  
instrument cluster?
