Just a heads up for anyone having Dozer issues....
I recently started having issues with the dozer not behaving correctly during multiball, it would stall, especially if I was flipping anything, so it would just randomly stop half-way at times blocking the shot into Ted's mouth, or just acting all kinds of weird, especially if the dozer was trying to move while I was flipping.
I knew I needed a power board rebuild, as I was having random resets and used a Khar board for a while to stabilize the game, but I was noticing things were progressing for the worse. I did the rebuild last night, and can say this also has fixed my dozer problems entirely. So if you are getting frustrated with the dozer, and have tried all the other fixes, might be time to look at a power board rebuild.
