I checked all of the rectifiers on the board and all tested good. One of the connectors was a little burnt so I went ahead and changed it out and my control lights came on. All of the lights worked except for one below the left spinner. I saw it was a red wire with a green stripe. I found a red with green wire on the lamp board, checked it, and wasn't getting continuity so I replaced the wire but the light wasn't coming on when it was supposed to; it is supposed to come on when you hit the top stand-up target but it was on without hitting anything. I got to looking at some of the other control lights and saw another one that wasn't working- the left most light for the stand-up targets that you knock down for the bonus multiplier and it turns out that light has the exact same red with green wire so I swapped my new wire to where the other red with green wire is and the light below the spinner that I put the new wire on lights properly now when I hit the upper stand-up target.
I started checking the other red with green wire and I was getting continuity from the connector to the wire on the lamp socket. I checked and I also am getting voltage but the light is not lighting up. I thought maybe something was wrong with the socket but I used a jumper wire from the lamp socket wire next to it and the light will light up nice and bright. There were a couple times that the problematic light would light up but it was dim and if I wiggled the bulb it would go out and not come back on until I re-booted the game and it didn't come back every time I re-booted the game. I pulled the light board and re-flowed that pin but it didn't change anything. I then did the test where you hook up to TP6 on the MPU and touch the wire for the light in question and the test led lit up which I believe verifies the scr, trace, and connection is good. I also stuffed a wire in the back of the connector, verified I had continuity and voltage on the added wire but the light still wouldn't light.
One thing that is also weird is once I was able to get my control lights back on after replacing the connector and crimp contacts was I was only getting something around 3volts at TP1 on the power driver board and on the control lights buss wire. After I replaced the wire for the first red with green wire I noticed my lights were brighter so I checked voltage at TP1 on the power driver board and the control lights buss wire and was getting a little over 5 volts.
Any ideas on what is going on or what I need to check next? Are the two red with green wires related even though they do different functions or is it coincidence and the factory just happened to use the same wire on two different control lights and that I had problems with both?
