Apologies for lack of knowledge, first time getting dirty under the playfield!
So my Diner arrived the other day, looking super hot as they're want to do. It's been in storage for a while waiting for Le Gentleman Mover Martin to pay East London a visit. After a few games I noticed a bit of a weird one - random drains registering mid game. It seemed to happen as a result of other switch hits - spinner, ball lock, right sling and right inlane all seemed to trigger it occasionally, but never consistently. Initially it seemed as though these random indications can be caused by diode failures, but looking at the switch candidates, it didn't really seem to form the usual 'rectangle' pattern in the matrix.
Today I've been playing around with the trough switches in the Edge Test, and Trough 3 isn't registering when i hit it manually.
I jumpered the cables between the row and the column under the playfield, and Trough 3 isn't trigger when I jumper these ones:

But Trough 3 is triggering when I jumper these ones:

Soooo I guess this could discount the CPU being the issue?
Does it sound as though I need to replace this switch? And more importantly - could this faulty switch be causing my ball drain issue?
