There were some issues with AMH's where some switches were wired backwards in production. This causes some switch hits to trigger other switches, which you will see in the switch test. I have heard of issues between the sling switches and trough switches more than once, so suspect this may be your issue. Check the switch test and see what hitting the sling does.

Hi Guys - I have AMH side rails that are NOS. One small imperfection in the finish from the factory, but otherwise excellent. I'd like these to go to an AMH in need, so if anyone needs side rails, you can have them for free, just pay for shipping. PM me.

PS - I miss the game!

Good Seller!
That AMH is still a big hit in my house and at a local show.

Hello and thank you for the quick reply.

Unfortunately, It doesn't do anything. It won't show either the right sling OR the trough being activated.

Maybe the switches are bad, or not making contact. You could connect a continuity meter (with the game off) and try closing them by hand. The sling firing could have vibrated enough to unstick the trough switch, but now, it's truly dead... maybe.

I’ll double check that when I head back to the arcade this afternoon. Thank you

That kit is fantastic and super-rare. Really brings the theme to life.

Had one of those games where everything came together, my best score before this was like 70K. Got to battle the demon three times with the extra balls and didn't even know about the "Bumps in the Night" mode. The beginning of the demon mode is legitimately creepy.

Just a quick follow up to anyone wanting to know what happened and/or may have the same issue somewhere down the road...

I literally took each color wire and followed it from the "troubled location" to the backbox. The White and Blue wire is connected to the second trough switch, also to the right slingshot and then is connected to the left target bank (associated to the right ramp). The wire had come off of the left target bank but was lying so close to the switch that it was intermittently making contact, making me second guess everything that I was doing and/or looking for to fix. lol

Needless to say... I resoldered the wire to the switch and viola!

Thank you to everyone who offered suggestions.

ANy updated videos or gameplay/tutorial....May try and rejoin the club....

If did one recently…

Finally got my AMH shopped out.

Added:
Medisinyl set
Green precision flippers
white star post lights
green footprints on ramp
blue/blue pop ring light (just upper right)
Titan glow rubbers
Laserrific topper

Super happy with the way it turned out!

Still need to add the colordmd and audio dac upgrade.

What’s the audio dac upgrade?

Love the Hellevator alteration for #150. Brilliant!

Would just need to print out the Theater Ghost eyes to fix the line up on the backboard (unfortunately the art positioning isn't consistent from game to game--picture frames have leeway to look right amongst the variance, but the eyes needed to be exact to the positioning of my game to work as designed, so printing out the eyes on paper and applying behind the panel is needed to solve for that).

EDIT: and if questioning, the mounting tape should survive if pulling that panel to fix it, and remount with no issue or reapplication of the tape (had done this with my RZ gas station before with the same mounting tape with no issue).

Looks great! Love that kit. Someday Ill add this back. A friend just sold one. The only complaint I hear is you need to add some beefier servos and it would be nice if it could be coded to be a little easier.

A higher quality digital to audio converter (DAC) can be added to the Pinheck board to improve the quality of the callouts. Search this thread for "DAC" and you'll see all the threads.

herg posted a great guide on his website as well:

Still need to get that kit installed... just not enough hours in the week...

Hey Club!

While playing a game yesterday I noticed I have lost all switches in Column 3. None of them register. All other switches work - it's just the three switches in column 3 on the Green-Yellow wire.

I swapped IC3 and IC4 and the problem remained so it's not the buffer chip.

Switches themselves are ok (checked with meter).

Wondering if a shorted diode on one of the switches would cause this behavior.

Looking for suggestions before I start desolderong stuff.

Thanks!

Solved. Broken wire from Pinheck to the first switch in the chain. Didn't catch it right away because there isn't any extra wire in the loom and it looked like it was still connected.

Had to bend the lug on the switch to get it to reach the wire after stripping and fortunately that was close enough to let me resolder.

Proud new owner of a loaded up AMH! Couple questions.

1. Is there an option for the chroma lcd color upgrade to adjust the backlight brightness, contrast, settings, etc?

2. Is there a list of all the 3D printable add ons to help the flow of the game and fix ball hangups. just want to make sure I have them all.

3. any option for a shaker?

4. anyone have an extra main board for sale? Thanks in advance!
