Quoted from Sirgubster9:
Guys in test menu it says I have an error and that I should go to switches and so I did and I have trunk lid in red. I feel like the game plays just fine unless it's not doing something and I just don't know what that something is. Is this normal, or should trunk lid be green?
There is a leaf switch behind the lid, only visible when the playfield is slid back. It probably has a broken wire. Sort of common. My understanding is the game will play fine without the switch working. I think it was planned for it to be coded in for something, but never made it in. If anything it helps determine the catapult accuracy. Still...I resoldered mine. The error drove me crazy.
