Just got Earthshaker it's saying in diagnostics that Lower ball pop needs attention and in switch test mode it is continually. I've tested the wires going from PF to backbox they aren't shorted together and they are each showing continuity to from switch to pin individually. I can't even when blades are together to get the Green black wire or and the white grey to show they are connected (to short). I also have entered switch test phase on MPU menu with the pin connection removed from enter connect board and it does not show it as active. My first glase showed me I'm missing the diode so I installed one but it didn't help. I'm trying to make sure I install this missing diode (1N4004) correctly on the Lower ball pop. Does the diode's stripe go to the green/black wire attached at the rear of the switch?
I have the stripe to the green cable not the white.
<b>UPDATE:</B> Looking a photos posted below it looks like mine only has 2 points on soldiering contact pads where as the Williams replacement part A-11658 shows three. This as was confirmed that indeed the top pop has three points of contact yet my lower pop only has two. (see posts #4-6)
I'm farily new to working on Pinball so sorry if this is a basic question
