Thanks for the picture and for all the suggestions. They really helped. With switch testing, it worked, and it was high enough, but I found out the kicker attached to the coil was too high so the ball couldn't reach the switch. Under the play field I found it disconnected forward so that it would still fire. Once I got it reattached it all works fine.
Re: the other issue, it's only when the ball isn't hit hard enough to make it all the way around the loop. Switch is working. I'll work on adjusting the height.
I don't want to keep posting issues, but want to make sure I'm not doing something stupid. I ran a solenoid test and the mars lamp wants to turn, but can't initiate. One in ten might go okay. If you nudge it, it will rotate fine. I think unrelated, but at the same time the opto switch to my supercharger now only intermittently works. Switch testing also only has if intermittently working. There's lots of posts on opto switches here, but do you suspect it to be a loose wire or cold solder? Am I burning out the mars lamp if it isn't able to rotate? (It worked a week ago)
