Hi everyone, first time posting in this thread, I just finished swapping to a new CPR playfield, and have all new Alltek boards, MPU, Solenoid , Lamp/LED, and Aux/LED boards, and a new rectifier board beside the transformer. All of the test points on the rectifier board have the appropriate voltages, but the solenoid board LED's are not lit up for 12VDC, or 5VDC. Nothing is lit up on the MPU board. No displays are working , nor are any contolled lamps. GI lights are the only thing on. I am including a picture showing the backbox before changing all of the boards, and there are black and red jumper wires connected to the big blue Capacitor on the solenoid board. The Black is going to a single white/brown striped wire, and the red is going to an orange wire twisted together with a red/brown? striped wire, which run up close to the P3 connector.
Can anyone please help me determine the following,
A, what to do with these wires that I mentioned above, where do they connect to?
B, What else can I check as to why I don't have 12VDC and 5VDC on the solenoid board?

I have reseated everything a few times, on the boards, male/female disconnects, etc.
Thanks for the help! pictures are worth 1000 words, Thanks in advance!!

Can anyone please send me a close up picture of connector J3 on the solenoid board? I think that the 3 loose wires that I have belong in places 10,11 and 12 , and I just want to verify. Also, where is the best place to get that 25 pin .100 connector? I would like to get it from Digikey if possible, but I have no idea how to look it up, as I don't exactly know what to call it. Thanks!
