Pinsiders -

Good evening. Hokus Pokus quit working a few months back. After testing coils, running through the start up sequences, cleaning switches I have identified the issue but not sure how to make the correction. Manually resetting the bonus step unit. Can start a game and everything sets up to play ball #1.

When ball #1 drains. Outhole switch closes. Score motor starts. Bonus relay energizes but will not hold to score the bonus. Score motor keeps cycling. Bonus relay also keeps pulling in. Not sure why it's not holding.

If I manually hold the bonus relay in during the score motor cycle process. It does score the bonus, outhole kicks out the ball, increments to ball #2. Can simulate all the way through game over.

Traced through the schematic back to the score motor switches, bonus relay, and double bonus relay, and outhole relay. Cleaned and adjusted all the switches using the schematic. Cannot get the relay to hold to score the bonus.

Anyone out there with a HP that has had this issue? Any information you'd be willing to share would be greatly appreciated.

Just looked through the relays bonus and double bonus no contacts touching. No loose wires.

Going to pull the lower board and look through everything again.

Trilogybeer,

Appreciate the response. I've cleaned and adjusted all contacts on the lower board. The bonus unit and the credit unit. That being said still have the issue where game isn't functioning properly. Going to walk back through all the relays and switches. This believe or not is why I love this hobby as a collector. The payoff is solving the problem. Again appreciate the advice...OHEMIO

Rolf will look at these particular area's tomorrow morning. Appreciate you pointing me into a specific area of the game to locate the potential fix...OHEMIO

Gentlemen

Happy to report that the issue was found and we are back up and running 100%.

I spent a lot of time working on the lower board, on the credit unit, and really just filed and cleaned the switches on all three. Even found one disconnected wire on the 2nd player score reel.

Checked contacts and connections more on the lower board and where I thought I had issues.

Today based on Trilogybeer's advice and specifically looking at Rolf's specific switches. I located the issue. Also thanks to you Phil-Lee for chiming in.

White-Yellow wire disconnected from the bonus unit switch from his diagram. So buried under the score unit you can hardly see it on visual inspection.

Should have stuck to the more simple things first per Trilogybeer...connections and switch evaluation in every location of the game first.

Absolutely love the game play of this pin. A lot of fun to play. Can't thank everyone enough for all the assistance!

Rolf I do have the schematics and manual. Although I did use them for some of the issues I had. I'll say that I'm still learning to read them well.

Again appreciate all of your time and help. Onto the next project total basket case Williams Triple Strike single player. Complete restoration including maybe my first playfield restorations

Will definitely be a learning experience...
