That's great. Do you have a manual? Do you have a DMM and a logic probe?
Quoted from jag8511:The top Jet bumper wasn't working and had the coil sleeve melted inside of it.
This kind of damage has done damage to the CPU board for sure. I would also bet that the fuses are not the correct value, when getting a used machine you must check all fuses before you even plug it in.
Quoted from jag8511:So I decided to tackle the first problem and bought a new coil and rebuilt the lower part of the bumper. Turned the machine on and tested and nothing. The coil wouldn't fire. I then looked at the CPU board and noticed that Q79 and Q78 looked to be a bit burnt. I decided to replace them both. Put the CPU back in and turned the game on. Within about 5 seconds, Q79 started to spark and smoke. I turned the machine off immediately. Thought maybe I had a bad transistor so I replaced Q79 again. Turn the machine on and again it started sparking and smoking.
You need to test first before randomly replacing parts. There is a limited number of times that you can replace a TIP before you damage the board.
Let me know when you have the tools and I will assist you in fixing these minor repairs.
