Charger Specialties Circuit Boards

Recently I replaced the circuit boards in my Barracuda with new one from Charger Specialties. When I got everything back together, the temp and oil pressure gauges stopped working. So I pulled the dash back out and noticed a glob of solder that was touching both the bottom pins where these gauges connect. I carefully removed the glob and put it all back together. Gauges still don't work.

Has anyone has this type of problem with their boards?

never used them.
did the gauges work before?

did you test them?
2 AA batteries in series wired to each side. they are slow to respond so give it a little bit see if they move.

Have you contacted the supplier with your problem to see if they can help or have any suggestions?

I have one but have not installed it yet. I know there is some specific instructions did you follow them?

Yes, the gauges worked before I swapped the boards.

Yes, I contacted the manufacturer who told me to test the voltage.

They did not come with instructions, but they are very simple to install.
