So my Sega Baywatch is blowing F7 fuse on PPBoard. so no 32v. No flashers and no coils.
Replacing the F7 going in diag and run test on cycling coils (or cycling flashers doesn't matter), will blow up the F7 fuse.
Running the cycling flashers test will cycle up some coils for some reason.
With game off I did a quick check on all Q transistors and cpu and they all look ok to me. (Q29 is the one switching the K1 relay in theory)
With game on and grounding the Q29 doesn't seem to get K1 relay to click. But instead blows the F7 fuse. (quite spectacular)
I checked PPBoard components and they all seem fine. No idea how to check the K1 relay, but everything else was ok.
Looked under the playfield for shorted wires going to any flashers and coils and did not find anything strange.
Don't have any hacked wires/connectors on boards, nothing toasted, or weird looking.
The game was working and I was the last one I played on it before buying it. The only thing I did back home is to remove all fuses and install the correct ones. Like I do in all the games. I had a mixed bag of wtf fuses. Like a 15A, 20A and one that was a simple wire soldered across the fuse ends...
Any idea on where to look next? To at least narrow it, if is something on boards (which one PPB or CPU) or is something under the playfield?
