Hello,

I recently picked up a Whitewater Pinball machine in overall very good condition that has been sitting for a while. It had a very small amount of battery acid leakage that dripped lightly on the WPC board which I removed, carefully addressed with white vinegar and cleaned up along with a couple of issues (lost mine coil and ball return / trough were sluggish) which I cleaned and are working well now.

The game played for a few games but then the Big Foot head started to spin both clockwise and counter clockwise and will not stop. Since it doesn't stop spinning I can't start a game and upon boot up I get "Big Foot error not set"

I went into the test menu and into the Big Foot Test with the following results.

-When in the big foot test mode, I can do the following:

-Head position test I get the message that "Head position is unknown" error

-I can make the head spin in both directions using + & - buttonsPosition test head position unkown (resized).jpg.

-In Opto test mode, the number 2 opto is checked but then the system freezes up and I can't get out of that test mode. I have to restart the game to get back to the beginning.

-All coils, flippers, lights, functions, ect work in test mode.

- I removed the small Opto board and it looked clean, no burnt components or signs of issues. I cleaned both sides of the Opto switches, but still no luck.

Any help / advise / guidance on what to try next is greatly appreciated.

Thanks

Moe

Hello wdennie,

Thanks for your advice. I performed a switch test on the Opto switches and found that Opto 2 is Open and Opto 1 is Closed.

I'm not sure if Optos on this game should be in normally-open or normally- closed, but it seems one of them is not right..

I also included pics

Please let me know your thoughts.

Thanks again

Thank you wdennie and Scoot!

The head doesn't rotate during the "Switch Test", however it does rotate and I can change directions in the "Big Foot" test mode.

In the "Switch Test" nothing moves and I just get a read out of the test. I can't toggle anything in Switch Test mode.

Scoot, I appreciate your input on the servo possiblility. I will research if the motor uses one on this game.

Thanks again

Moe

Much appreciated wdennie. I ordered one and should have it sometime next week & will provide an update.

Thanks again!

Moe
