Workmaster 55 Tachometer and fuel gauge questions

[MrWhippy]

Sometimes, especially when the temperatures have dropped in the last 24-48, the fuel gauge and tach fail to register a reading while the tractor is running. Sometimes they will suddenly begin to respond to the sending units and read correctly. Sometimes not. The problem is very sporadic. I feeling is likely a spade connector needs to be better seated and that when the temps drop, there is enough shrinkage that there's a poor contact until the tractor heats up sufficiently.

Anybody else seen this? Suggestions on other possible explanations?

I have a 2013? Workmaster 55 that has done this since it was practically new. Did you happen to find a solution?
