Shadow, The
Bally, 1994My Battlefield arm is not moving well to the right. When it goes left it is quick and fast but back to the right it jitters and struggles to move. It does have the brass pinion and the shaft slides are not lubricated. I looked at everything and all the wires appear to be attached. Also manually moved it back and forth and it does feel similar both directions. I'm not sure what to do to solve. Any suggestions are appreciated. Thanks
Might be the flipper opto board. Try switching the left/right boards and see if the jitters switch sides.
Wipe the rods down with rubbing alcohol.
the sliders get gunked up and carbon and dirt that builds up in it makes it sticky.
It may look good but just like coil sleeves it gets built up inside.
In test does it go right fine?
If it does, still clean the rods. And clean your flipper optos with a qtip and Windex.
Quoted from jawjaw:Check the optos in the switch matrix test. Sounds like one is flickering on and off.
Can you be a little more detailed regarding how to do this test? Thanks
Update on this still unresolved issue. Everything structurally is sound and clean. When the game is first fired up the arm will actully work perfectly when it tests and also the first few times the ball is shot up there, but about the third time up there the arm will stop moving to the right smoothly. Not sure why it would work and then not work. Could that be an Opto? If so, would it be the right or left one?

Are you familiar with the switch tests in the menu? It shows you a grid and gives you a visual of all open/closed switches. For any switch issues, you start there and see what is going on with glass off. To test optos, just put something to block the light beam. You should hear a sound and see the switch close on the switch matrix. Raise up the battlefield, find all the optos (manual should help do that, and test each opto.

try it in test with multiple back and forth tests, see if it slows down the more ya use it.
I'll bet you have a broken wire. I went through the same scenario with mine and found the wire broken just under the coating at the edge of the solder. While I was at it I replaced the wires with a silicone coated, more flexible wire I had left over from my slot car days. They do move back and forth quite a bit and so does the guide flag of a slot car.
I have similar problem with friend's machine.
I'm 99% sure that it optos problem,because the first have broken houses(the plastic part that cover them),and when I adjust them little closer the battlefield works fine until they need to be adjust again.It left to be replace both of them,but when I have time and will report.

Having gone through the same thing, this would be my guess as well.
SOLVED- Finally ordered an Opto from Marco. Figured it would be a good $20 gamble if it fixed it. Thought it was the left Opto if either one because it looked terrible. Both of them worked fine in test mode so I was not real optimistic. Just before jumping in and pulling the left Opto I ran the Mini Playfield test. This test has been hit and miss this entire time with the issue. Today though after running it a couple of times it said I had a bad Opto but it was the right one. Keep in mind that my entire issue has been the arm hanging upon the left side. So I went ahead and changed the Right side Opto, which was not my original intention and it fixed this problem. Thanks to all who posted here and helped identify things to try and look for.
