Well I went up to Ocala to day and got into the TAF. Here's what I found:
No power to the coin door. No light in the "start" button.
CPU boot properly, with the correct LED displays on the board. All fuses checked out good. No burnt or broken connectors on any boards. No loose or disconnected wires.
I did find some anomalies with the connectors and the printed information in the manual: Coin door connector runs through the Coin Door Interface board to J206 and J208 on the CPU - this machine has them plugged into J207 and J209 (directly underneath - same key plug). Don't know if someone took them off and put them back in the wrong slots, I switched them to the proper slots with no affect.
On the Coin Door Interface the schmatic calls for a connector at J5 for the Test Switch, Service Credit Switch, Coin Slots, etc. There is no J5, that connector is connected to J3 with corresponding identifications for the ground, coin slots, etc. Is this an upgrade? A misprint in the manual?
I ran a jumper off the Coin Door Interface J3 ground connector and was able to get to go into the Utilities. The service switch, + switch, and test switch all worked, but the - switch did not. With the ground jumper I still had no power to the rest of the coin door and the start button was still dead.
I changed the machine to free play and it was holding those settings after 30 minutes of being turned off.
I'm a little over my head on this one and sure could use some ideas. I don't want to drag the machine down here. It is in a game room over his garage with a two-landing, turning set of stairs. Besides, it was a Treasure Cove high end restoration and it was delivered by professional movers. I've tuned it up, put on a remote battery holder, replaced bulbs, shopped the playfield, and installed new rubbers over the years - but we've never had any "board" issues. It sat unplayed for about a year and these problems were discovered when the owner replaced the batteries last month.
Hope somebody out there can help me figure this out.
