Quoted from ItsBwalt:Haha thanks guys!! Okay before I go poking... Do I need to worry about getting zapped hahaha I feel like with the game on I'm gonna get zapped! Lmao
No you wont get zapped if you LEAVE THE COIN DOOR OPEN; That will cut off the high power. You should be able to do all your testing by hand with the game on, raise and lower the playfield just fine. You take a somwhat small risk of doing damage to the game when working with the power on and tools in your hand if they make a bridge between some things...so just be careful not touching too many things down there. Stay focused at the task and area at hand.
If this is your first time working on a Stern machine, puling the playfield out and pushing it back in there is a small lip it will travel over. This means the game wont slide easily all the way down...it will hit a small barrier and you'll have give it a little push to make it over. That's normal.
EDIT: remember, when you know the switch is working with your hand, you really need to test it with a ball. It can work fine with your hand but not the ball which doesn't help. Same thing, menu, switch test, push the ball in the scoop. The switch should register and kick the ball out.
