Quoted from Ecw0930:Ok guys ... My optos are going nuts again.
The coils won't test.
But the optos are just flipping out. All of them. Thought I had it fixed but tonight they went bonkers again. It won't even start now and when I test the switches all the optos will go nuts.
But the main one is the center target. It won't even respond. The others ones click on and off with the slightest vibration. The center one isn't registering again.
I can't have a game that is like this. And I just got it a couple weeks ago.
What is a good, solid, going to last, solution?
First thing you need to do is make sure you didn't create a short somewhere with the mods you added. I would start by disconnecting anything not stock. Check the optos and opto boards out closely for shorts, bad solder joints, loose connectors, etc. Then trace the opto board connections up to the main boards and make sure nothing looks fishy there. For the ones that are activating with slight vibration, make sure that the optos themselves are tight and not flopping around, and there is nothing near them that could be moving into their path. If the center one isn't responding at all, and the connections/solder, etc are good, you may have to replace that one. Thankfully they are cheap and easy to replace. There's an off hand chance one bad one could be making the others act funky. Optos can be strange. I had one go bad that would activate when I touched a nearby ramp with my finger. Crazy stuff.
For "coils won't test", are you remembering to pull out your interlock switch? Coils will not fire with the coin door open unless the switch is pulled.
Good luck!
