The power driver board test point for the 50 volts test results is 75 volts. I assume there is something wrong but i have no idea on where to look.

Thanks

thanks guys. just trying to trace down probable causes for some switch issues. more post to come.

at first it was a weird row 1 and row 2 error. I tested the main board and everything was good there. I narrowed it down to the 10 switch opto board. i pulled the cap and saw that it was leaking. Cap juice was also under the lm339. replaced both of those. row switch issues are gone. now i have 2 switch errors. Switch 51 and 71. I replaced the optos because i had them on hand. checked the voltages on the optos and they are correct and respond when an object is in its path. so i have no clue as to why the game isnt seeing those 2 switches as being closed. i am taking the 10 switch opto board to test on a friends dracula to see if its the board or if its something else in the game.

i already looked over the board for cold solder joints on header pins and other places.

switch 51 amd 71. i tried the 10 switch opto board in another dracula and it works perfectly. i have tested the cpu board with the row and column touching with the lead. all rows and columns light up as i touch them. i am at a total loss now.

it has a rotten dog board

yep there was a bad hack job wire repair by previous owner. pulled out the repair and resoldered it and works now.
