Home late tonight and only got a short time to tinker with Hot Tip.

My first issue tonight. Turn the machine on, press start, the machine does its thing, but doesn't reset drop targets or shoot ball to shooter lane. If I press the left flipper button once (or sometimes I have to do it multiple times), the Outhole Relay then kicks in and the drops reset and the ball is kicked into the shooter lane. I went back through the last lot of posts and it said that I needed to ensure the zero position contact on the bonus unit was making a closed circuit. I saw that this was visually closed, but when I pressed the left flipper button, I could see a spark coming from this switch. I noticed that all these switches had been bent and I'm guessing that an owner from years gone by has been "adjusting" these switches. I adjusted this switch and now when it is in the zero position, the drop targets reset and the ball is kicked to the shooter lane.

Once the ball is in play, I knock down a few drop targets, but once again the ball isn't recognised in the outhole. Another issue I noticed, if the bonus unit isn't in the zero position (if the switch is open), I press the start button on a game and nothing resets. I have to manually move the bonus unit to zero and press start before a game will start. The mechanism is fine, but it is not resetting at the start of a game.

I haven't tested anything with a multimeter yet. Is there something I should be investigating with the multimeter the next time I work on the machine?

Cheers!
