Upon power-up, the mpu led flashes the 7 times, after the 7th flash the F3 fuse blows. Any help or ideas where to look will be appreciated. Thanks.

The MPU, Solenoid driver, and Lamp driver, have all been recently replaced with new Alltech and Rottendog boards. As far as I know (owned for only 3 months) the sound boards are original, Bally-sound plus and vocalizer. I did unplug the input to the Sound plus board, same thing happened, but the playfield lights started to flash like normal before the fuse blew this time.

did that, it only blows when the J3 plug is connected. All the voltages on the rectifier check right also.

I have discovered, if I unplug J1 on the MPU board, it doesn't blow the fuse.

YEP, still does it. They are Bally displays, appear to be original.

Hey, thanks for the help Xenon75 and Barakandl. You guys got me headed in the direction enough that I found it. It is the aux lamp driver. After 9 fuses and a lot of trial and error, and reading the book and schematics, and following your leads! Wish I could find a 4amp circuit breaker! Kudos to pinside.
