I am finishing up a full restoration on my Seawitch and i no longer have access to the photos i took as i was taking the game apart. If someone could please post some pics of the inside of the cabinet and head to show how the ground strap is secured and connected inside the cabinet and head i would be very appreciative. Once i finish the restoratiin i will post some pics of the final result.
Quoted from rcbrown316:do you still need this? I am tearing mine down and putting in a new PF after I restore all the mechanicals and verify operation/performance.

Yes I do need them if you have taken some.
Thank you
Quoted from rcbrown316:mainly in the head then?
I could use ones in the head and cabinet area.
Thank you.
I am hoping someone here has seen this issue. I am finishing a restoration on my Seawitch complete with Greatwich playfield and having some switch issues. When the spinner switch is closed it instantly fires the right slingshot. The right inlane and the left outlane also do not work at all with no scoring or sound on those two switches. I have been looking for a short in the area of the spinner switch and have traced the white with green stripe wire. All but the left outline are on the same row of switches. Any ideas would be appreciated.

Does it happen when all drop targets are up? If it only happens when certain drop targets are down, exactly which ones?
If you start game and then remove the J3 cabinet switch harness from the MPU board, does the spinner issue still occur?

Thanks for the reply. Yes it still does the same thing with J3 on the MPU unplugged and with all drop targets up. When you run the switch test and operate the spinner it shows switch 5 which is the spinner and also 13 which is the right slingshot. It has me stumped for sure.
Quoted from Mad_Dog_Coin_Op:One of those two switches likely has a bad diode or a diode that is shorting out.
Thanks for the reply. I have changed them out already with no effect.
Quoted from cottonm4:OK. Here come Joe Shadetree. When nothing else works.......
Make a jumper wire with a contact pin crimped on. Install an alligator clip.
** Get your Y-R wire out of the picture.
Remove the Y-R wire at connector A4J2-5. Install your jumper wire. This will disable all 8 switches on row ST4
Since the left outlane is all on its lonesome touch your alligator clip of the left outlane switch and see if that gets it to working. If it gets that switch to work, then possibly something is wrong with your Y-R wire. ??
Next, do the same for the other three switches by touching the right inlane Y-R wire at the right outlane.
If this leaves you still searching, then repeat the above at A4J2-2 B-W wire for r/h slingshot.
And you can also do this for the A4J2-1 W-R wire.
It may or it may not help you, but since you have tried everything else, why not?
I did something similar awhile back. It did not isolate my problem but it got me to looking around and found I had a pinched wire under a piece of metal.
All 4 of your switches that are having problems are hooked to the Y-R wire. I would look at all solder joints at all of the switch connections on the Y-R wire. And, as mentioned above, isolate the Y-R wire by using a jumper.
No promises.
I appreciate the suggestion. I will do it this weekend and report back my findings. I think it is something like what was wrong with yours but I am not having much luck finding it.
Still chasing my problem on my Seawitch. Can someone send a picture of the wiring on the right slingshot please? I want to make sure mine is correct as part of running this issue down. I appreciate everyones help on here.
Quoted from gdonovan:Can someone be a sport and post pictures of the 5 connectors on the solenoid board so I can confirm what the wiring schematics state? Thanks!
Here you go. Hope this helps

Helped me get my game going. I had the white and green wire on the coil and not the switch on the right pop bumper. Embarassing to say the least but thank you for posting thr pic.
