Help!
So I've just started putting back a bally six million dollar man. I have installed a homepin rectifier board, and had put the whole thing back together.
Turned it on with just J2 at the rectifier, confirmed voltages, then plugged in J3 and confirmed voltages on the SDB.
Plugged everything in, everything working. Had about a dozen games, adjusted all of the playfield switches and lamps. Was super happy so I turned it off to remove a display.
When I turned it back it it flickered on and off rapidly several times and now doesn't power on at all. The power LED on the rectifier board does not come on.
Troubleshooting so far.
Replaced cabinet on off switch, replaced wall plug
confirmed continuity (live, neutral and ground) from wall plug all the way to J2 at the rectifier board.
----- EDIT : I've just discovered that the wiring out of the line filter had been reversed and therefore 230v was coming into the rectifier board at J7 (blue) which was suppose to be the return. I have corrected this at the switch so that now 230v (Australian) at pin 6 of J2 connector (yellow wire). -----
So as far as I can see I'm getting power as far as the J2 connector but the rectifier board power LED isn't lighting.
Trouble shooting continues:
I have removed transformer and rectifier board from headbox and confirm no loose connections, and test continuity from all transformer lugs to solderpads on rectifier board.
I have confirmed that there is 230V at lug 1 of the transformer. And between 1 and 7.
There are no voltages coming off any of the other lugs except lug 8 and 10 which both have 5v AC coming from them referencing to ground, but 0V when measuring between 8 and 10.
I can only conclude that my transformer has died! But I read that this is incredibly rare, perhaps the rectifier board has died?
So I need your help
Is there anything else I can look for, have I missed anything - and how can I test my transformer for faults?
