Hi guys, great forum. Just wondering if anyone can help with a problem I seem to be having with my machine.

A couple of years ago I had the main board replaced with a new repo one then put in into storage. When in normal dispaly mode(not playing) the tilt will come on and off switching all the game board lights off, sometimes for minutes at a time. With the board up you can see and hear the relay clicking on and off.

It seems to play fine for the most part, but after the ball goes down the shoot the tilt flashes and the tilt chime sounds, just for a second. It still spits the next ball out to play again and all 5 balls seem to work fine but after the game ends the tilt relay buzzes loudly.

When I first pluged it in last week I had no flippers, poppers or targets which pointed to the game over relay. I turned it off, cleaned it, tapped it and it seemed to fix it.

I cleaned and adjusted the tilt switches both on the door and next to the LH flipper button but it seemed to make no difference.

I did try the search but came up empty, any help would be fantastic.

cheers

There is a fantastic resto thread with a couple of good links but they did not help. I was hoping someone could tell me what might be triggering the tilt.

The bob is disabled so it's not that, I would guess it's electrical but I'm not sure. I was hoping there was a common fault with the tilt someone might be aware of.

Thanks guys, as said earlier the slam switches are closed. Just having a read through the link now. cheers

Ok so I have a Wi-Wumph board and there are no ground mods done yet and it still has the origonal c1 cap too so I will start with these. The pic of the Wi-Wumph board is different to mine, can anyone confirm where the ground mod goes on these boards.

If I turn the game on and just leave it its fine for a couple of minutes then the relays start to humm loudly then it tilts. Sometimes it untilts for a few second then tilts again.

This was all they had, its upright not longways. It shouldn't matter, right?

It does, just my board looks a little different. I will post a pic of it later.

Hi guys, I did the groung mods and fitted the bigger cap during the week and it seems to have fixed the problem. Even tho my plugs have bbeen repinned at some stage a couple of the pins were still a little low so I bent them up.

I was hoping the mods may have helped with another intermittent problem I have always had, as you can see from the pic at some stage someone has replaced the 5a slowblow fuse with a 5a circut breaker. Sometimes I can play 10 games in a row without it popping and sometimes it will trip 10 games in a row.

Could it just be that because it's no longer a slowblow it trips too easily?
