Quoted from squad8:
I probed j4 pin 11 on the mpu, and it stays low in game play, and solenoid test.
And it was right there, right under my nose, all along. Went to probe this pin, but noticed that it wasn’t there? Went to my notes from these threads, and I had a note that MPUJ4-11 should go to VSU J3-5. But, on my pin it looks like VSU J3-5 is going to MPU J4-9. I moved the wire from J4-9 to J4-11, and “one, two, three” etc. !!!
So i am posting the before and after photos. It reminds me of a concept I like very much: Sometimes a small change can make a big difference.”
Thank you to everyone for all your input.
