Power supply is fixed so, instead of starting a new thread, I changed this one. LED Problems.
I'm working on a Bally Centaur which hasn't been powered on in a long time. Before connecting the boards and playfield I wanted to check the power at the module board in the bottom of the cab. I reflowed all the pins along with replacing the bridges and 5v rectifying diodes. When I switch the game on I get the wall voltage (116v) all the way to the connector leading into the transformer. But, with my black lead on the ground and my red at any of the test points, set to DC, I'm not getting anything. Am I missing something? I added a pic of what I have connected. All the fuses are good too including the one in the tube. I did add a new line cord with the smooth wire at the hot and the ribbed one on neutral but what would that matter if they should be reversed? It's AC voltage anyway. Advice would be appreciated. Thanks.
