Wiring issue

well, i am sending you images right now. and am not sure, whenever soldering wire between 2 and 3 would fix it, since that problem seems to be on spot before nr. 2...more in a pic.

Got it. I think the high resistance is caused by a oxidised track, likely to be a short circuit and heated up.

Easy solder between the two points.

...aaand sure enough it worked system is purged and primed now, thanks for help, Richard.
