This is a new to me games, X's & O's that I have been working on. There has been a number of repairs that I have made to this pin so far to get it to a point where I could play a few games as I work the bugs out. That is up till now, At start up the coils lock on at power up. I turned the game off and on a few times and the coils did not lock on anymore until I turned the game off to make another repair. I can see if just one or two locked on but all of them at one time? What should I look for?

Yes but it will blows everytime i turn the pin on.

Bump

Yes, When this first happen I was just testing the Aux Lamp Driver board, where I just got done removing the old solder on the header pins with my Hakko and re soldering them. (which fixed the problem), I also bulletproofed the solenoid driver board a few weeks back.

Odd, I just turned the pin back on and the solenoids did not lock up at all
