I searched the threads for this topic, but no go. I picked up a blackout and it had battery damage on CPU, cleaned it up and neutralized it. Put brand new interconnect on both Mpu and driver. Both male and female are brand new and have very good connection. Changed out all the fuses for brand new ones. Put all new caps on power supply and power supply works in my time warp and scorpion. At this point I think it's something simple but not sure.

The game goes into audits because of no battery yet, but I'm going to solder in a new off board three battery.

Any rate, I go into audits option 2 and shut down then start back up and get attract mode no problem. Coins up, starts game and no kickout, no coin door coil energizing, = absolutely no coils. Points register fine and flippers work. Just not one playfield coil energizing.

I know it's something simple, but with 60 hours of work a week for the past few weeks, I'm too exhausted to have much energy left.

Once again, any help is greatly appreciated.

First check the bridge rectifier (BR2) I think it's an orange wire - looking for about 28 VDC.

If that's good then check a coil under the playfield - again looking for 28 VDC.

If that's good then check that the coil will fire. Use a jumper wire and ground the other wire on the coil (just touch it quickly to ground)

If the coil fires then the problem is on the driver board.
