Hi ale (is that right?)
The problem had to do with either connectors not-quite-mated, or perhaps a signal out of range due to contact issues .. perhaps not enough pressure, or corrosion, or ???
It was a male connector on the board and a female connector on a pigtail to the current sensor. I think both ends are tinned. Soldering is not an option, since you need to be able to assemble/replace parts. BTW- I use crimp connectors whenever possible. I mess up soldering ... and have had solder wick up into the stranded wire and make for a less flexible connection past the strain relief. I have had failures in cables as far as 6 inches from where the solder was done (let's not discuss HOW MUCH solder I used!). After bending back and forth many times (vibration) the wire just breaks off inside the insulation, where you can't see it. This is *VERY* tough to find.
