Quoted from Chaos:Thanks rygar, that will be a big help.
Can I start the machine with every one of those disconnected, and is there any particular order that would be best to connect one at a time after that?
With the flippers activating, is it likely that the problem is at top left there on the fliptronics board or the ribbon cable connection there? Or is that not "assumable"?
No word from anyone on whether I must switch off the machine as soon as those flippers start up activated or the fuse is blown, or if I can leave the machine on to check what led's are lit up?
It's hard to note the LED's at the same time I am scrambling for the plug to switch the machine off.

If you power on any game and immediately any coil locks on, power the game off immediately. Best case you will blow a fuse. Worst case, you will fry board components and coils. You can try opening the coin door and see if the coils no longer lock on.
If the coils are locking on, you have a direct short to ground. It's very bad. In the game, coils are pulsed, never fully powered like that. So it's quite dangerous to the components.
You can power on with any of the ribbon cables disconnected. First step is isolate the CPU board on the lower left. It has 3 LEDs. When properly booted up, one will be in a flashing state. Remove the ribbon cables from that board and power on. If you get the flashing led, CPU booted. Time to attach the next cable.
You sure you didn't get the video and aux cable backwards? The CPU board seems to have those two cables the same size. See the photos above and make sure the cable on the far left of the CPU board is run to the small aux board not the display board.
