Did another test on the ac relay. I stopped the self test on ac relay and decided to measure the voltage on the board..
Across the tabs coil and NC i got 32v dc
Across NC and DRV flucuate between 0 and 10v.
All the others i got nothing.
The tab that says 28v does not have anything soldered on it.
During the test the fuse is ok. Fuse only blows at the end of the game. Trys to kick out all the balls into the shooter lane and some flash globes light up for a few seconds.
I have resoldered the board aswell..
Still no idea were to go..
