When I first received my TX the clock didn't work. After rebooting a couple of times it seemed fine. Then the display board stopped working. I played with the connecters and that came back. Then the Extra Ball Switch stopped. Then the game started feeding me 2 balls at a time. Then when the ball went down the slot machine shoot the slot machine didn't spin on the display. The ball wasn't recognized. the game cycles through all the coils and shot the ball back out. Then the F115 fuse on the power driver board started blowing. I sent the power driver board, MPU board and the dot matrix board back to the person I bought the game from. He told me he checked all 3 in his game and they were fine. After I reinstalled the boards The F601 fuse on the dot matrix board blew as soon as I switched the game on. I took a little break and installed a new flipper coil. I had a box between the playfield and the cabinet. I turned the game on and it blew the F601 fuse on the dot matrix board but didn't blow the F115 fuse on the power driver board and the flippers worked. I placed the playfield back down to the cabinet and there was a large spark and the F115 fuse on the power driver board blew. At that point I knew there was a short. The apron was crushing the opto wires and shorting. I pulled the wires away from any metal and turned the game on again and now it was blowing the power box fuse. Dead, no power. I finally disconnected the dot matrix board completely, the power box fuse doesn't blow anymore and the F115 fuse on the power driver board doesn't blow. But now the flasher lights on the playfield stay on. The dot matrix board was reworked oat one time, I wonder if that could be part of the problem?

I bought and replaced the game with all new ribbons. I took detailed pictures of all the connectors on all the boards before I removed them. I checked, double checked, and triple checked. Everything is connected correctly.

I was told the game was in perfect working condition. It was bought from a basement game room and moved to a warehouse, and then shipped by freight 2,000 miles to me.

Don't you have to remove one end of a resister, diode, or cap to get an accurate reading? If not how can I tell if one is bad?

When I plug connecter J605 from the transformer secondary into the dot matrix controller board the F601 +62V circuit the fuse blows as well as the power supply fuse. The book says the two white wires from connecter J605 from the transformer secondary should be 80VAC, I tested 85.2VAC and the two purple wires from connecter J605 from the transformer secondary should be 100VAC, I tested 107.1VAC. I'm thinking too much voltage?
