Quoted from TheCapn:Chances are you may have an MPU issue, but to help troubleshoot. I would check to see if you can manually fire each solenoid by grounding the tabs of the transistors very momentarily.Do you have any battery damage? Where the batteries sit is a common location for damage to the special solenoid section.

Okay... I did not want to waste anyones time on simple stuff I could research on my own. So I dug a bit deeper on this. I was fortunate to have some spare parts from a few other DE games. I swapped out the MPU Boards and both worked fine. Swapped out 3 PPB board, one of them a known working board. As I said before Powerboard was giving good power on all test points. SO....
I was blowing the 3A fuse on F7 on all the PPB boards which installed (they all blew instantly.) This seem to result in, or it occurred at the same time of Q46 transistor blowing. (okay if I am going to be very honest here... on the last attempt I over-fused the F7 to a 5 amp and the transistor blew with a puff of smoke)
I pull up in my manual and Q46 is 1L 6-Ball Assembly Lockout and 1R Top right Police Lights flashers
So what am I looking for her in the 6-Ball Assembly area? (I will of course check the R police flasher on the top, but since they have been enclosed in their plastic for years I do not foresee a problem (unless it is with the wires leading to them.)
(Full disclosure I have recently removed a ton of parts (including the 6-Ball Assembly) when i stripped the PF down to bare wood on the topside and removed every scoop / crome part to polish. Honestly I could have re-solder something wrong or maybe my coil is bad in the 6-Ball assm???)
and I have already reflowed solder on boards and replace several related connectors on the Power board and PPB board... so I do not think I am have a connector issue.
