So I've got this SS with the following issues. Could any, or all of these be board related?

Coin door solenoid stays energized

Diagnostic switches don't work

One pop bumper stays energized, and a second fires intermittently when a game is started which in turn blows the 2.5A SB solenoid fuse if the machine is left on for to long

The bank of three targets does not raise when a game is started like they should, but pulsate up and down like they are trying to.

The flippers do not work at all

Hey Vid!! The buzzing doesn't bother me because the door is closed. I just know that it is always on and wasn't sure if that was supposed to be that way, or is how it's supposed to operate

All fuses in the backbox check out fine

The mech is smooth and operates fine by hand

I just did that and they are not firing,now I now have working flippers along with everything else but the pops as expected. I've rebuilt the pops so could it be that the leaf switches are out of adjustment?

You've done it again Vid!! In my rush to get the pops back together I had completely forgotten to readjust the leafs and two of them were pretty much completely closed. I have read your pop rebuild kit numerous times over before too so shame on me lol. Thanks once again!!
