Quoted from NPO:Paging
It looks like you (all) are right on track and most things have already asked to check:
Quoted from DumbAss:Q24 and Q34 on your power driver board one or possibly both will be shorted.
Quoted from dmacy:see if something is shorted to those flasher holders/associated solenoids.
Quoted from DumbAss:There are tieback diodes to J122 and J126.
Quoted from NPO:TIP102: Put the black lead of the DMM on the metal tab of the transistor. Put the red lead of the DMM on each of the two outside legs of the transistor.
but I have some concerns about this:
Quoted from drummermike:The two round projector lights that are in between the start and movie lights come on and stay on.
Those 2 flashers (#25) are also driven through J122, together with sol. #26 ramp down.
By pulling J122 the fuse would not blow.
It makes me think that the PowerDriverBoard is wrong plugged, or a short on playfield between flasher and solenoid or a blown drive chip (U2) on PDB.
Would like to see a picture of the powerdriver of connectors J122 to J132.
