Bally Centaur Playfield Swap

(1/3) > >>

Strangeways:
This job is different from what I usually do, but it was an interesting adventure. Initially, it was a repair, which was related to some of the GI not working correctly and some switch issues. The switch issues were easy fixed, but the GI was difficult. Basically, only a couple GI lamps were working, and then the power supply would overheat and shutdown. So I had around 15 minutes of diagnosis before I had to switch off the machine. It was either a short with a wire or a socket. I thought it might BE the SCR or the Aux board, but they were ruled out once I replaced them.


While this was happening, the owner decided to have the playfield replaced with a new one. So when it arrived it went straight to Tim for a re clear. This was a good outcome, as the new playfield in the machine had a number of issues that I didn't like - The metal parts were stripped of their Zinc coating and then dipped in oil to stop the inevitable surface corrosion from starting. So that game me the opportunity to plate and rebuild the underside correctly.


Since it was a repair that turned into a playfield swap, it is presented here differently.


Here are the original photos from 2-3 years ago of the playfield ;






















While diagnosing the problem, I removed assemblies and that's when I found the mechs had been stripped and badly re assembled ;











Have a look at the dodgy pin on the RHS drop target !











Stripped plating on all assemblies..





















GI Culprit found !









So well hidden, that it took half the playfield to be stripped in order to find it !














Continue with the playfield strip ;









.. and I'm done !









and here is the replacement playfield, that @el_timbo86 cleared to perfection !







What a beautiful playfield !

Bloody lucky it turned into a rebuild that short would have been a night mare to find. 

    Gotta love a centaur
