Finally found my grail pin. Started repairs on cabinet and stripping playfield. I will give a thorough cleaning and clear coat. Will paint cabinet also. Seller brought it from San Diego to me in Arizona.

He has family 14 minutes from me and was really cool to do it free of charge. Soundboard rebuilt and he repaired all drop target boards. Will get new ones from Marco since cheap. It also has a new backglass and Comet LEDs.

Couple questions. What’s a good speaker upgrade for it? I was thinking about this one, but don’t want to risk damaging soundboard. Found this newer version from post here 6 years ago. Pyramid 8” 8ohm 200 watt subwoofer.

It came with a Rottendog combo MPU/Driver board. Seller says when the magnet is released the pop bumpers and slings activate. Is this a normal quirk? He tried to figure out a fix but no luck?

Appreciate any help and can’t wait to finish Gorgar and get playing. Will go next to my Stern Dracula.

Use gorilla glue

The board in it is the 374-4 from 2018. I emailed Jim at Rottendog and hopefully he has an answer. Don’t want to buy another board since I just bought Gorgar. Not a huge problem, but it will really annoy me.

Thanks for your input on the speaker. Will go ahead and pick it up. Thanks so much!

Going through my Gorgar and found 2 wires that were not soldered on. Both red wires, one for pop bumper and one for a sling shot coil. Hopefully that may be the culprit of pop bumpers and sling shots triggering when magnet is released.

Cleaning and getting playfield ready for clear coat. Will update.

Started restoration. Playfield clear coated.Pinball Pimp Stencils should arrive on Monday hopefully, but priority mail has sucked as of late. Pinball Life order will be here Monday also.Can’t wait to get Gorgar done and finally play my grail pin.

Thanks! Me to!! Too bad it’s been on average 115 degrees here in Arizona

Will do!

I will run the sub and mid speaker a parallel circuit or chained together.

Playfield all done. Just have one drop target to adjust that isn’t going down well. Pinball Pimp stencils due to arrive tomorrow.

I would buy new wire.
https://pinside.com/pinball/market/shops/1041-third-coast-pinball/00662-18ga-stranded-tinned-bare-wire

Put the new wire down and then do a direct transfer. Take plenty of pics for reference. Do not trust your memory or finding pics on line. When labeling I used different colors of 1/4 electrical tape I had or painters tape and then numbered the wires when I used painters tape.

I would transfer one wire harness and all connected to it, disconnect it and transferred to the new playfield. I did that on my wife’s cyclone. I just got into pinball last year and it was our 2nd pin and my first pinball task.

Goodluck

Started stencils today. White all done today on cabinet.

Assembly time. Can’t wait to finally play it. Haven’t played it since I bought it in July. Went right into the restoration.

Does anyone have a pic of their GOR drop target wiring if you used new updated drop target slider boards? can you please post a pic for me please?

I bought a Gorgar I am trying to finish the restoration on and when the G drop target is hit it resets pops back up and scores even if the O and R drop targets are still up.

Also the magnet is not working. It came with the Rottendog mpu driver combo board that I just got back from being repaired. Magnet doesn’t come on with switch. Will test magnet resistance and continuity and switch contacts. It has a new coil for the magnet. Everything else works ok on Gorgar. Thanks for any help.

Awesome!! Do I still need to use the original diodes or no? Thanks so much!

It came already with Gorgar when I bought it. I looked at mine and the boards for GOR are out of order when compared to the illustration. Previous owner kept the original diodes on when he put the new boards on.

Thank you!

Going to check the magnet for continuity and make sure it’s still good. Also going to check the switch.

Here’s how it’s wired with the original diodes in. Can I just solder the wires to the board directly without the diodes or just keep them there? Hopefully the photo clarifies it better.

The boards are also in the wrong order so that’s probably why the G drop target resets everything when it drops regardless if the O and R are up.

Also magnet not working. Have continuity but reading zero ohms. Should there be an ohm reading? Thank you so much

Also magnet not working. Have continuity but reading zero ohms. I assume there should be an ohm reading of 4.5

I pulled the magnet and getting 0 ohms and it’s black towards the center. Will check the wires on the switch. Will look for some pics online to compare to mine unless you have one? Also will check my manual. Thanks for your help.

Thanks so much! I cleaned the switch contacts for the magnet in the snake pit. When the switch was a hit the magnet relay coil fires now. So looks like all I need to do is get the magnet and that issue will be fixed. Hopefully anyway.

Getting 0 ohms on the magnet. Should there be any resistance on it? I have continuity though.

Put magnet back in and now it’s working oddly enough. Prior before I put magnet back in 20 amp fuse blew for GI and now lost all GI. When I turn game on with another 20 amp fuse it got orange hot. I Turned it off before it blew. Was working fine and so damn close to getting this Gorgar 100%. This is the hardest restoration for me to get going and working fully. Thanks for the help

8FC76C43-0646-47D8-9FB5-0A0BE53D2C6F (resized).jpeg

thank you so very much! I will go through and remove each bulb on the Playfield after I pull the harness and turn it on and see if the fuse blows or not. Then same for the back box. It’s crazy it worked and then stopped.

Definitely has to be a wire on the Playfield since it’s been up and down a few times. Need to go Sherlock Holmes and do some detective work. So damn close to being done. Did full restoration with pinball Pimp stencils and just want to finally enjoy the game.

Would you bother to replace the magnet? Mine is working but I am reading 0 ohms on it. I assume it’s not the strongest magnet regardless. Mine looks like it shorted at some point and is black on the center. See pic I posted. My gut says if it’s working leave it alone.

Thanks again for the reply, really appreciate it!

Ok here’s what is going on with my GI fuse blowing. I unsoldered all the wires and isolated which one was blowing the fuse. It’s the yellow wire for the play field GI.
I soldered just that wire back to the fuse and I Pulled all the lights out with the playfield propped up resting where the lock down bar goes. Put one light in at a time and all the GI lights worked and fuse didn’t blow.
When I go to put the playfield down near to the down position, it starts to short the GI fuse and lights go out. I raise it up and it’s ok. So at this point not sure what it’s coming in contact with to cause it to short out. Can’t see any wires being pinched or anything obvious.
Got the magnet to work and the GOR drop target. Only thing I did prior to 20 amp GI fuse blowing was to screw the C upper play field roll over light socket to the play field.

Found out what was causing the short. The GI braided wire was coming in contact with one of the screws that screw into the wood trim.

Now I lost lights on row 5 and found bad resistor at R134 2J7 on Rottendog MPU/Driver combo board. Changed out resistor and swapped out working resistor to R134 to verify and lights work now. Anyone have idea what resistor this is? According to resistor calculator it’s a 0.62 ohm 5% but can’t find one or the schematics to confirm.

Had the guy who does my board work verify the resistor for me. Definitely 0.62 ohm. Wasn’t sure if band was silver or grey

Master display went out and found a burnt resistor and some other bad ones. Would you repair 41 year old board or buy a new xpin display kit and no worries about the board going out?

Have to put in new magnet and wait for Rottendog mpu driver board resistor to arrive. This Gorgar restoration will hopefully get finished at some point. Fix one problem then a new one pops up. Taking forever.

I ordered the XPIN on eBay from same seller. Had in my cart and he offered it for $179. Glad I did it. You did well on the slave displays. I will do the same. Selling 4 slaves definitely takes a big chunk of the cost from the xpin cost. How do you like them? Thanks for your reply.

That’s so cool that he is so laid back and very approachable and easy to talk to. That definitely is a great plus for me. Can’t wait to get them. Definitely happy I went with the new displays. Thank you.Appreciate the replies and feedback. Will post when I receive them.

Just get this speaker. I installed it and sounds great. No reason to spend crazy money on a game with sound effects and soundboard from 1979. This speaker still gives nice base tone along with nice mids.

You are very welcome. You will be happy with it and save some money.

That needs to be on a Motley Crue pin!

It takes sometime. Take pics as you go. I did it on mine
