Hey guys,

So, recently I installed a new coil sleeve and re-aligned my shooter lane solenoid. Unfortunately upon bootup, something got crazy and the shooter lane solenoid no longer works. It did work once, and then I strongly believe that both the solenoid's lugs were on the leaf switches of the right flipper, and I caused something to short out . I get 0 volts at both lugs of the solenoid on my DMM with one lead on one lug and the other on ground. All of my other solenoids are getting power, so I know it is isolated to just my shooter lane solenoid.

So, on HS2, there is a high current driver board on the top left of the PF (this is with the PF propped up against the backbox) with two IDC connectors. One connector goes to the shooter lane solenoid; the other goes to the rest of the wiring harness to the machine.

After a solid night and morning of diagnosis and many tests, I found that I have continuity from the brown/yellow wire of the IDC connector on the high current driver board to the other end which is at J127. For the other wire - the purple/orange stripe wire, the manual shows it going back to J107. I traced the wiring through the machine, and this wire goes straight from the IDC connector on the high current board to the J107 connector - at least that is what the manual shows. So I ran a continuity test there - nothing. Then I noticed J109 had the exact same kind of wire, so for kicks, I did a continuity test there - and the audible chirp went off - indicating continuity - even though the manual shows it should go to J107.

So, here's the question - can someone with a HS2 verify my results? I know that every once in a while the manuals are wrong, but this is something that could mean possibly a fried board, so I'm just asking for someone to verify my results.

Later today, I am swapping BSD and HS2's cpu boards to see if the problem follows BSD. If it does, I know it is in the cpu board. If not, I am thinking the driver board may have something wrong with it.

Needless to say, until I fix this, my FS thread for HS2 is on hold/suspended.

Help.

Fuse continuity checked out.

I didn't desolder the coil lugs; everything stayed solid.

Thank you ! It makes me wonder if something is fried on the driver board now..ugh D: ...

Is there any other right way ?

Yes, absolutely off the board .

There is no diode mounted on HS2's shooter lane solenoid . In the process of swapping cpu boards right now. Been a long 18 hrs D:

CPU board swap complete. BSD works perfectly. Eyeballing the driver board now .

Not trying to be an ass, but can you be a bit more specific? There's lots of things on the driver board D: ...!!

I'm totally grateful for any help .

I think I know what you're getting at now.

On this game, there is a high current driver board, and on that board is a diode. It is the only diode in the circuit - to the best of my knowledge, and it check out good at 0.551v.

GOT IT!

Broken purple/orange wire somewhere between J107-2 and the high current driver board underneath the PF. Ran a jumper wire of equal gauge from the bottom pop bumper to the current driver board - since they are both on the same circuit with the same voltage - and I am back up!!!!!

I'll do a GoPro video soon of what I did and the steps I took to rectify this issue for everyone.

It must have singed and broken the wire but not the insulation when I shorted the shooter plunger solenoid lugs with the leaf switch of the right flipper. The correct fuse is installed - so why it did not blow that first puzzles me - but oh well!

Man, I may not sell this bad boy now. I fell in love with it again fixing it. Is this the pinball version of the Florence Nightingale effect o_O ?????

Big huge shout outs to Mark Combs of Mark's Pinball and Scott Weir of WeirPinball - thank you so much to both of you for your guidance, knowledge, and assistance.

YEAH!!!!!!!

Video of what was wrong, diagnosis, and how it was repaired here.

I may need to make some small annotations as I made some quick assumptions in the video. GoPro videos get very big very quickly, so I tried to keep it short. Any questions, please don't hesitate to ask.

Glad to help - absolutely!

I am blessed enough to have both great resources and know extraordinarily knowledgeable people in this hobby. The very least I can do is share that wealth!
