My Temp Gauge and Fuel Gauge aren't working...

Same problem here on dad's 69 Dart. No temp or gas gauge. I pulled the plug off the back of the cluster on the left hand side. Plugged it back in, temp gauge now works. Am I right to assume I've probably got some loose pins in the circuit board? Gas gauge worked as recent as a few months ago, but has been dead since the temp gauge went out. Dad is probably gonna bite the bullet and get a new board, as we're gonna have everything apart to install new dash bezels from BE&A Parts. I'll pop in a new regulator while it's all apart.:thumblef:

I used the tiny trim nails/brads and backed up all the pins into both of the circuit boards on my Dart. most of the pins were loose and the solder cracked away so unless you tweaked the connectors just right the gages on that side and lights would come and go. Since I redid all the pins almost 20 years ago the gages and lights are like a rock, no more off and on of anything that is sposed to work as long as the sender and limiter is good.
Most of the mopar cars use similar circuit boards and pins so the fix applies to just about any of them.
I now have a 78 dodge van I scored cheap that has a few issues and one of them is loose connectors and pins on the dash circuit boards, if I decide to do some more repairs that is one of the things I will do to it as well, as the gages work if you tweak the connectors as well.
Just remember to insulate the back of the metal plate that the boards mount on or you could possibly someday short out the dash if any of the repairs are sticking out a bit farther then the stock boards and pins.
