Any guidance will be greatly appreciated as I feel like I have exhausted my research from the past few weeks. If you can provide any links that would aid in my testing it would also be greatly appreciated. I'm having an issue when the ball drains into the bottom out hole the game doesn't register the drain. The ball is kicked out by the solenoid at the beginning of the game but once in play the drain switch doesn't register when the ball drains. The leaf switch does make contact after the ball drains. The white and brown wire also connects to the far right out hole roll over drain as well and this switch is also not working. I have tested the white and brown wire and also the green and red wire that is connected to the drain leaf switch all the way to the auxiliary board and was able to get a signal over both wires. The brown and white wire also goes to the middle drop targets which also work. Any direction would be super and sorry as I am new to the troubleshooting process. I was thinking of changing out the leaf switches but am also unsure of which one i need to purchase a tad confusing. Thanks again, and yes I am a newb but unsure where to turn.

Have you done a switch test through the setup function to see if works during the test? Go to Internet pinball database and download the operator manual. It will explain how to do it.

Check the diodes on both switches and make sure they are okay. Set your multimeter to ohms and check the continuity of the diodes.

Do you have the playfield schematics?

You need to look at the switch matrix; sw9= Outhole, sw25=Center 3 bank left (2000/5000), sw33=Top 3 bank left (2000/5000),sw41= Right outlane rollover (2000). Check these switches with the switch test or in game to see if they are registering. You said the right outlane wasn't working so it looks like row 1 of the switch inputs may be out. This is 2J3 pin 9 connector, that could be bad, or IC15 (MC14049) or anything else along that path.
