Any ideas on how to fix the oil pressure gauge without having to take it somewhere and spend $300 to troubleshoot it or worst yet buy a whole new cluster (~$1,200)? I have some pretty decent electronics background to test for basic things. I am about to take it apart and see if I can find any obvious problems with the gauge like cold solder joint or damaged component. Does anyone have any ideas what to look for or what to replace?
