OP

Quoted from bbddpp:

Wanted to stop by the thread and update everyone and again also say thanks for all the expertise here. I feel like I learn something new with every problem and while I'm not the fastest I'm at least learning.
So in looking at the switch wiring and the help of other photos you shared I was able to see the proper lugs for the in and out wires for these standup switches. I had some wires frayed and loose under there and did my best job to solder them up (soldering upside down was tough, not sure I did the best job on that one). These switches are really in tight spots with a lot around them.
Anyway, lo and behold, after the solder and verifying all 3 switches worked in test mode, reconnected the disc motor line and my jaw dropped. They were no longer shorting out and working properly!!! I am ecstatic. I will likely say this problem was caused by errant switch wiring putting current where it should not have been but I may never know.
Of course with that fixed it's on to the next problem. One of them is my power board causing resets. The rottendog board isn't doing it so I'm attaching a photo for Grumpy to take a look at. He's thinking the board may need some work. I imagine this is stock.
There's also the matter of the left flipper not resting nearly high enough when held down, power seems decent but boy is it low, can't even trap a ball there. Something I will need to investigate remedies for.
So happy to see the discs working again, and I can at least play test games with the Rottendog board in until I get my stock board serviced.
