Just joined the club!
Giving this game the royal treatment.
Bought tons of new parts to do a Full topside and underside tear down/cleaning/refurbish all mechs and whatnot.
Also Full LEDs. Flipper Fidelity speakers.
Been wanting a mousin' around for over 5 years.
Will post before/after pics once complete.

Oh, side note- anyone selling a Mousin Around interconnect board. The one in the game is fried in a few spots. May fix it myself but would prefer to grab a lightly used or NOS board (reached out to Tony at Great Lakes Modular about his MA interconnect boards but no response).

I recently bought lots of parts to fix up mine and I think Marco may have had them or Curly may have them at Little Shop of Games.

Finished restoring my Mousin Around. Based on comments from the seller I believe this game was quite possibly HUO and never had a full tear down before.
Gave it the works. Full topside tear down, all mechs underneath rebuilt with new parts, upgraded flippers, new interconnect board, LEDs throughout and threw in a full set of flipper fidelity speakers.
Playfield in nice shape with day-1 Mylar that I brought back to a shine using a car headlight polishing kit (highly recommend trying it if you want to get Mylar shiny).
Game plays absolutely amazing and the speakers add quite a bit of oomph when the mouse catcher talks.

Thanks!
They are the same conical shaped post rubbers that the game came with but found blue ones from a vendor at Pinfest. When shopping a game I like to add post rubbers that match the color of the playfield section they are on to blend into the game better. Hence the blue rubbers at the ramp enterances. I couldn't find red conical rubbers which is why you'll also see yellow ones on some of the other posts.

Also I love that the conical rubber posts prevent the ball from bouncing off the playfiel. Super helpful in Mousin Around since it's a wickedly fast game.

Thanks Hilton! This was a fun game to shop. And I will see what I can do about getting to MAd Rollin. This darn work/family thing always gets in the way of pinball fun

Finally got around to installing the metal-mods pop bumper decals on my mousin around. I opted to not use the circular metal decal around the outside of the pop caps since the leds I have in my pop bumpers are only in the middle.
Long story short, they look great and are easy to install. And they dampen the led intensity perfectly!

I removed my playfield when I was shopping it/changing bulbs. That’s the easiest way. Plus, that’s also a good time to clean the mechanical stuff back there. I guarantee there will be a bit of buildup.

Correct. Label all the connectors going through the head into the cabinet. Then disconnect them.
Then I lifted mine straight up and out and gently leaned it up against my game and worked on all those hard to reach sections.
Oh, and lay a towel over the side of your cabinet before leaning the playfield against it just to prevent scratches to the side artwork.

Yes. Either that one or the one from Little Shop of Games. I think I got mine from Little shop of games when I replaced it but had to redrill the holes a tiny bit to fit properly.

I’m curious as well. Does anything different happen when you head to the mouse hole? Ball locks up there since there are multiple switches?

I did a full topside tear down as well as removed/cleaned/updated all underside mechs. And LED’s everywhere except flashers.
Not a terribly difficult game to shop but getting to the back diverter mech is a pain.
Best to pull the playfield out to do that section. I have tons of pics from my teardown if you bump into any problems.
Good luck and enjoy!

Yup.
I disconnected all the wiring I could from the backbox boards and carefully lifted the playfield out then stod it on end next to my game to work on the mouse hole mechanics.
Wasn't too bad (or too heavy to pull out on my own) since I had already removed everything from the topside of the playfield.

Hey guys
Just replaced all the original capacitors on my power supply board.
Started the game and it powered up fine. Went to test TP4 and got 0 volts instead of -12V
Tested TP1 and got 10V instead of 5V.
Tested TP3 and got 26V instead of 12V.

New capacitors I put in:
https://www.greatplainselectronics.com/proddetail.asp?prod=W12246-PEC-KIT

Thoughts? Is this correct volt readings since some of the capacitors are larger values than the originals?

So I’ve been working on my MA and realized I may have an extra ROM in my game that doesn’t need to be there.
Can anyone confirm if there are supposed to be 3 sound roms in the sound board?
Or do I need to move my rom in U20 to U21 on the CPU board.
This “extra rom” may explain why I do t get the “bong” sound at startup.

Good to know! Thank you!

I will remove it and see how the game plays and get back to everyone. Thanks for this additional insight Soren!!!

Pulled the chip.
Game still plays/sounds the same.
(Thanks Soren!)

But still no startup “bong” sound when I turn it on.

Wondering if the Flipper Fidelity speaker system I have installed is causing the game to not “bong” because it has its own amplifier (I believe) for the woofer.

BTW- Flipper Fidelity speakers in MA sound amazing and really brighten up the music and provide such better sound clarity.

This is awesome info. Thank you again Soren!

My MA manual talks about the “bongs” so I’m guessing they should be there but since the game plays/sounds perfect I’ll assume the lack of a startup bong is because I have aftermarket speakers that have an amplified woofer.
Been tinkering with my MA the past few weeks of furlough and learning a ton about system 11 boards. Good stuff!

Aftermarket.

Hahahaha. I literally just pulled the same link to send the OP.

Op- I recommend reading through this manual to get familiar with your game.
Has info about the bulbs, rubber parts, mechanicals and more.

I recommend these.
I have them on mine.
The yellow "sliced cheese" look compliments the game as well.
Also recommend yellow flipper rubber.

With Mousin around I recommend using incandescent flashers. Not LEDs.
That’s what I did and I like the results.
However I did use LEDs on the GI and inserts.

I have the same board from Herg in my Mousin' Around.
It works flawlessly.

I disassembled and cleaned my diverter thoroughly when I bought my mousin’ and afterwards it has been flawless. There is a plastic “cog” that can get gummed up if someone put a lubricant on it. That could also be part of the problem but fixable after a good cleaning.

I’ve never tried it but I hear you can sometimes reactivate the adhesiveness by using a hairdryer to heat it up.
I defer to others who have tried this to confirm if it works or not.

No offense taken whatsoever! Glad to know I should avoid the hairdryer “trick” should my Mousin Mylar start lifting!

I love that the cat is sniffing your Mousin around in that pic!

I don’t hear a startup bong on my Mousin either. And I am running the Soren code. It’s awesome!!

Both.
Metal on top or right sling. Clear plastic star on top of left sling.

Not the best pic but you get the picture.
