Hi, I am trying to bring a Mata Hari Solid State back from the dead. When I got it it was missing all boards except for the Power Supply and transformer. All fuses were intact at this time.
I got the Alltek MPU board, Solenoid Board, and Lamp Driver Board, so I figured I would test the voltages at the test points on the rectifier board before hooking those boards up.
I plugged the machine in and fired it up. The only connector plugged into the power supply was J2 from the playfield. Fuse F6, 3 amp, blew almost immediately. I replaced the fuse and it blew again.
Where should I start troubleshooting this? I am handy with a multi-meter. Is there a way to isolate and test the transformer? Could the bridge rectifiers be at fault? I am more than ready to get this machine running!
