Machine is being weird. Sometimes it will start. Then a game our two into it left flipper gives slam tilt. Now the left and center pop bumpers start to go crazy. If they do left flipper gives slam tilt. If game starts, the slightest twist of cabinet starts the pop bumpers (left and center) going crazy. The diodes read 4.6 on the pops the slam tilt has a diode but I don't get any reading. Could this be the problem? Can I just unsolder the wire from the slam tilt?
