So I have not played this game since the 70's so my memories are a little vaugue to say he least.

I got this on eBay for $65 and Kawydud (John) was super nice to pick it up and bing it to a swap meet to save me an all day drive. There's power board issues but that's no big deal, I'm using my space invaders power board for now until I get a rebuild kit. After reseating chips, the game starts, coins up and plays besides the fact you can't aim shots. He red lights inside he scope only work if it's aimed all the way left or right. All shots only come from the left.

What is the board above the main board with all the pots?

Is there a manul scan anywhere online? I can't find one.

Any Sea Wolf owners have any tips or ideas?

It's also missing at least one sound I think.. Maybe more.

Edit: I just noticed that strip of explosions above the lamp board on the back of he scope. That's dead too.

The board with the pots is the soundboard. Each pot controls a particular sound's volume. (sonar ping, shot sound, pt buzz, etc). Repin your power connector and reseat all chips that have popped out of their sockets due to heat. There is a mod that should be done to fix or prevent coin-up problems. It entails soldering in wiring bridges between certain solder points (can't remember where, but if you search the web, you'll find it). Make sure to replace all burnt bulbs in the scope/ targeting mech. There is a test plug by your explosion lights that you can plug into to check them all at once. PM Orion or you can try and email Alex Yeckley for further, more thorough repair help.

Thanks for the info, Phet. The test plug was wrapped around the harness and I didn't even see it. All the lamps do come on when it's plugged in but they still don't come on if you hit something. I now have the pt boat buzz noise after fiddling with pots, but no ping.... Do you know what pot is the ping? Why is there no manual for this game scanned..
 
Ahh Seawolf great pick up. Great game that I would sometimes find stuffed in the back of a bar or movie theater. Funny fact is, I just got in touch with on of the creators of that game while trying to get some background story of Wizard of Wor. Come to find out that Ms. Gorf also worked on that with Dave Nutting Associates from Bally Midway. That game was created from right here in my home town. :D
 
I don't have a burner and don't have the confidence to stap the board anyhow... I feel if I did I'd mess something up and turn a mostly working board into crap...

Anyhow, I did this:

Opto Isolators.
Another potential problem is on the vertical part of the CPU board. At positions A and B across the top of the board there are two opto isolators. What these do is protect the boardset from bad or high voltage inputs on the control panel (like someone sorts higher than 5 volts to the control panel switches). If this happens, the ipto-isolators blow, saving the rest of the CPU board from damage. Great idea, but these opto-isolators are no longer available. Then can however be replaced with jumper wires, as shown in the pictures below.

And now it does not coin up :( the board looked slightly burnt by these things so I figure there's a good change they were bad.

Edit: the trace got lifted in the burned area. It coins again but still does not aim. I'll do the transistors tomorrow night and see if that takes care of it. This page http://users.wowway.com/~ookpik72/swrl.html says that those being bad can effect that and the explosion lights. It looks like a few have already been replaced years ago.

Is this heat sink thing normal on the sound board?View attachment 107408

That is just for the sound amp and I don't know if it is custom or from the manufacture that way. It is not a problem though.

If you pm me with your address I can send you one of the test chips. It is a 2716 that goes into the H position and you don't have to remove G.

That's great, thanks! pm sent.
 
So I got the scope working. Part of the problem was that the board above the back of the scope wasn't making contact enough with the little pin things that move with the scope. At first I loosened the screws and put some shims under it but since that board is so flexible I ended up cutting two strips of 1/8" wood to go under it and it's perfect.

Another question: the black light bulb that goes in here, is it like space invaders white black light or a real black light?

I was going to suggest shimming the periscope board, lol. Mine was already shimmed when I got it. The light should be a black tube, not the white black light. There's several manuals, bullentins and schematics listed about 3/4 of the way down this page.

Definitely replace the edge connectors as others have recommended. I was having all sorts of intermittant problems with mine, and after replacing all of them it's been rock solid. Awesome game. I call it my "Lays game", because you can't just play one round, you get sucked in for 30 minutes plus easliy. ;)

The inside of his thing is so clean and the edge connectors are so good that they are really hard to get on and off, compared to my Space Invaders and Clowns anyhow. I think I am going to let them be for now. I wouldn't saY this is a HUO game by any means but it's been in a house, not a warehouse, for a long time. Very well preserved.

I thought it was a black bulb, I'll grab one today. Thanks.

Mine was the same way, and I thought the same as you, but... I think the problem is that the original AMP connectors are so sharp that they cut into the pcb and start to lose contact, even though they're tight and visually look okay.

That's awesome that it's in such good shape. I remember it looking nice in the ebay ad. Man, you got a great deal! Post some pics when you get a chance.
 
Agreed. Those original connectors are absolute junk so at the first sign of trouble they should be replaced.

That is the LM354 amplifier....the heat sink is the standard package for it. If all your sounds are gone it is the first place to check. You can also test for all of the sounds by grounding pins on the boardset (description is on my repair page) to narrow down where you problem actually is....
