Hello
I am replacing a Stern Rectifier board (TA 100) with a RottenDog Bally/Stern Rectifier board (BPS018). I can not seem to find out how to wire it right. I have blown the fuse 6 once and tried to see the difference in wiring. Rottendog only gave me a wiring diagram that seems to work for a bally game plug and play. I am sorta lost right now. If anyone can point me into the right direction or have any experience with this let me know thanks.

If you have instructions based on Bally you should be able to use this image to figure out the Stern equivalent:

I am having trouble with the edge connectors as well, I am not sure if Bally is the has the same wiring as a stern. I believed they were plug and play, probably not the case. I will double check my wiring to the transformer. I have blown the Fuse 6 twice now figuring it out.

Thank you for your help.

Thank you for your help.

The headers should be pin compatible. What I would do is connect only 120VAC to the rectifier board and measure the voltages at the headers and confirm they match the Stern schematics. From there you can figure out specifically where your problem lies.

There should be instructions on pinrepair.com to isolate the rectifier board and check the voltages.
 
Lindsey,

You have been a great help. I think I found where I went wrong on wiring. I switch E1 and E4 going to the transformer. And when I am done doing that I will do what you suggested and Isolate the rectifier board and check the outputs. I will tell you how it goes. Thanks again.

I wired the game up, but for some reason I am not getting the 43v to start the mpu board. I think I am either dealing with a bad driver board or the transformer is bad. or maybe both.

Are you getting 43V at the rectifier board?

If not I would start by checking the voltage at the transformer winding (lugs 2 and 6). Make sure that tap is connected to the right places on the rectifier board then check fuse F4, the bridge (BR3) and finally the voltage out of the bridge to the headers. You could just check the fuse first but I assume you've already done that.

If you switched E1 and E4 points then you fed 110VAC directly to the 43V supply's bridge rectifier. Unfotunately, there is a high chance that this rectifier got taken out on your board.

I have tested the board and getting 43vdc but I am not getting the 5.4 vdc. Also I have tested the Transformer and I am getting readings all of the chart. I have noticed some corrosion on one of the sides of the transformer.
