Check Q45, or Q49 on the CPU, it may be shorted. I had a phantom problem like that on a Tommy & it turned out to be a shorted matrix drive transistor.

In the backbox there will be a board with batteries on it. Make sure the connectors are connected and did not bend a pin over when installed.

If you have not done it, you will want to make sure the batteries are fresh and good quality.

Before you mess around too much in the backbox, Just remove the tilt pengulum completely. Also check the tilt switch under the playfield in the extreme lower left. It is attached to the playfield underside. It just sounds like the tilt is being inadvertenly triggered. It might be almost touching already and is just super sensetive.

Is it giving you tilt warnings? Or re setting the game? If it is resetting, Then you may have undervolt issues on the power supply. Since you say it happens in multi ball, this is a possibility, since the beacons are running.

Sorry, i saw that its an actual tilt with a ball loss.

In the interim, go into your menu settings and increase the tilt warnings to ten, i think thats the maximum, That should keep you from losing games until we figure out the root issue.

One more thing. Checking transistors visually only occasionally shows you whats wrong. If they are shorted or have failed, thats usually internal. Youll need to get a digital multimeter and check for electrical flow through the transistor. I still suspect a rougue tilt switch. Chack that under playfield one.

It's not just cheating. It's a little bit of self defense for the machine. the plumb bob prevents long ball times due to nudging. The tilt under the playfield prevents drop tilting (lifting the machine and dropping it again) which can easily damage the machine if done too much. and the rolling ball prevents one from holding the machine up to keep you from reversing the travel of the ball if it goes into an outlane or something.
All may seem like overkill, but it would let the machine punish abusers a bit by taking away credits or balls.

Try adjusting the tilt count in the adjustments menu too. Sounds like it is set on one. I set all mine to three.

(my taxi has the plumb bob removed and I have found i like it better that way. somehow it makes the games more spirited!)

I had the same problem try this

find switch #57..... brown and white wires left sling shot , suck the solder off the switch pull them off the swich remove the diode too .... all ghosting should be cured ...

mine is and I was having the same problem

There is some mod that needs to be done on some sys11s that deals with the random tilting. I remember reading about it somewhere, but have never ran into this issue, and this haven't had to research it as such.

Try searching "tilts on system 11" on rgp. I'm too lazy right now, sorry =P

so what happened ? did you fix your tilting problem??

inquiring minds want to know

Hey Chef. Did this ever get fixed? I am having the same issue. It seemed to always happen when I was in the upper playing field. Played it for about a week then the tilt issue started. It did start after I worked on the switch for the spinner. I wonder if I hit anything?

I had the same problem it ended up being SRC6 (resistor/capacitor network). I hope that helps...

Thanks wbar. I noticed that it is consistently in the upper play field that it happens. Seems like when the ball hits one of the TOMCAT targets it tilts. Looks like it's on the TOM side. When I take the glass off I can't recreate it though. Also, I noticed immediately after the Tilt the "T"s #33 & #49 go out until the next ball is played. All the others are lite or flashing. It's like that every time.

BOK013 - I have the same issue with the targets causing the tilt. I wanted to replace SRC6 which everybody says will solve the problem, but I have a System 11b board in my F-14 - so there is no SRC6 on that board.

Did you figure it out?

Thanks

unfortunately when the tilt is associated with targets I don't think replacing the SRC6 will help. When I had my tilt problem on F-14 it was completely random, and would happen when it did not hit anything. I wish I could be more help. There are other threads with similar problem, do a search for "F-14 tilt" and hopefully you can get some answers.

Hey mclips. So sorry to take so long on this. Unfortunately, I haven't figured it out yet. I had a few other issues come up that were more of an issue and then I decided to buy a couple of more pins that always seem to need some attention. I am going to start hunting it down soon. I will post when I figure it out.

I'm working through the same issues with my F14, was their any resolution to this issue?
