Just finished restoring a High Speed. Everything works fine except at random times, either hideout will fire with no ball there and sometimes they both fire at the same time. It looks like the game thinks there are balls in the hideouts when there aren't. What makes me lean away from it being an issue with the switches is I can manually actuate them as well as put in ball in the hideout and they work as they are supposed to. It also doesn't always happen. I played three games and got multiball on all three with no issue. Other times the issue occurs. I haven't done any troubleshooting yet apart from testing the switches and playing the game. Wanted to get some advice from you guys. I did a search and found some threads with a similar issue, but they didn't discuss both of the hideouts firing. They pointed to a ground issue and suggested reflowing header pins since both the hideout coils share the same ground. I haven't had a chance to do that yet but in the assumption that someone has come across this issue before, I wanted to post and ask if anyone had some specific advice other than reflowing header pins. Also, I'm not too familiar with the game. Sometimes on a fresh game, when you hit the ramp for the first time, it will load the left hideout first. Other fresh games it will load the right hideout first. The diverters both work fine. I'm assuming it should load the left hideout first all the time? If so, then the machine thinks there's a ball in the left hideout when there's not. Had one game where it malfunctioned right after the first red light run. One more ramp hit would have started the multiball but it just ejected the ball from the right hideout and proceeded as if the multiball had ended even though it never started. Does that make sense?
Thanks for taking the time to read and respond (if you do). It's appreciated.
