HAD my new LW3 pinball working, shined up, and almost ready for play. We were even able to play a few quick games. Machine has new Rottendog MPU, PS and PPB boards installed. Went to finish LEDing the machine and now I keep blowing my 8A fuse that provides 13VAC for my lamps. Fuse blows IMMEDIATELY upon power up.
I have removed every single bulb from under the playfield, removed every single flasher bulb, tested every socket for a short to ground, checked BR1 and BR2 and got exactly the same readings (assuming they are OK).
I am stumped and about 15 fuses in at this point. Can anyone assist with helping me to figure out where my issue seems to be? PLEASE?
