i adjusted mine in switch test mode running the ball across the eddy board, tweeking the pot as i go

the pot needs to be fine tuned exact, once in switch test mode, PF up, run the ball across the eddy board, you will hear the beep of the switch while tuning the pot, fine tune from there, just need to play around with it, you might find your old boards were ok

note, been awhile since i did it, maybe missing something, see how you go?

I have experienced the same issue with my RS last year. As Skywalker stated, your old boards were probably A-OK. Assuming the electronics are working, there are really only 2 reasons the boards function intermittently. Either the pots that control adjustment are worn out, which causes them to "walk". Remember, this machine has a shaker motor, and that doesn't help. The other common issue is "cold" solder joints on the eddy board itself. A little touch up with an iron is all that is needed to rule out this cause for sure. Pinbits manufactures an updated version that needs no adjustment at all. It is currently out of stock but here is the link anyway. http://www.pinbits.com/index.php?main_page=product_info&cPath=13_25&products_id=203&zenid=25dbc42e0964241e76560e179b823492

I do not believe you can make this adjustment, watching/tweaking the red light Reliable/spoton during attract mode, super fine adjustment is needed here.

Road Show actually has 3 "eddy" boards under the playfield. One is located in front of the "dozer", and the second is loacted in front of "Red's" jaw and the last is under the dozer in front of "Ted's" jaw. The first course of action should be to swap the board locations to verify the problem "follows" the board. If this is in fact the case, assuming the electronics on the board itself are ok, there are 2 possible solutions you could try. You should touch up the solder at J1 and J2 on the suspect board and also at R2, the pot location, to rule out possible cold or cracked solder joints. If the board still falls out of adjustment, the pots are probably worn out. Remember RS has a shaker motor which could quite possibly cause the pot to "walk". That would explain the constant need to adjust them. Depending on your soldering skill level, the pot is really not that hard to replace. Also, a drop of crazy glue in the pot itself, sometimes works to hold it after it has been adjusted to where it should be, but remember that is really only a temporary fix. Cheers

All adjustments should be done in "switch test mode" not "attract mode"..

Best of luck, be sure to let us know things turn out.....

I would recommend the Pinbits replacement DannyFresh mentioned if it becomes available again. I was messing with that eddy board every time I played my RS and finally said "screw it" and bought the replacement from Pinbits and never looked back.

I am glad your RS is functioning normally again enjoy....
