Hi everybody, I'm having this problem with my new Baywatch (Sega 1995) pin. Hopefully anyone here can help out so I can start enjoying C.J., Jill, Erica and of course the Hoff!

When I bought the game, fuse F6 on the PPB was broken and none of the flashers working. So I replaced the fuse and then started a game: some flashers started burning brightly at the same time.

I then did a "Flasher test" from the diagnostic menu and all Flashers burn together. There must be some kind of short. I already measured all transistors (tip102/122, tip 36c) and they all tested out OK.

Where I should I look next? A short under the playfield? Some component on the board?

Thanks for any pointers!

Measure voltage at the flasher itself. Does it seem out of wack? Then measure voltage directly off the board that feeds those flashers power, is it the same voltage? Yes, then likely something driving them on the board is bad. If the voltage at the lamp is diffrent then you have a short somewhere, check the lamp bases make sure they are not touching something etc etc

hope this helps

Total 'greenhorn' suggestion. Don't flashers have a relay in the circuit? Maybe it's stuck on or no good. Not familiar with Sega, just wanted to give my 2 1/2 cents.

Everybody thanks for the suggestions. The problem was solved!

There are two connectors with the same amount of wires, the same key, and the same color wires. One goes in to the contra connector for the backbox light panel, the other goes to the the bottom right of the cpu board. My machine had the two of 'em swapped causing constant ground to the flashers.

To distinguish the two connectors, look at the wire coloring. They're both black, but the one that connects to the backbox light panel has colored dots on the wires. The other connector, which connects to the cpu board has completely black wires.

Baywatch is now 100% technically working. Next step: the cleanup!
