Have the opportunity to buy a Frankenstein machine but I might need some advice on its value:

Just saw the game for the first time and man it is dirty Seems complete though! Dmd 100%, starts up and you can start a game. 2 biggest problems: Frankenstein head does not move (his arms do) and sound does not work. Also the cabinet has some damage (worn around flipperbuttons, scratches over cabinet and splitting in 1 corner) and the playfield holes are worn. The MPU board is not the prettiest, but the other ones don't seem to have 'fixes' or acid-/batterydamage. Now to think of a fair price to offer

Any help would be appreciated!

Joined the club today
It is a mess, but I'm sure it will be nice when it is repaired and cleaned!
Unplayable at the moment, so gotta spend some time in it

My sarcophagus kicks the ball out way too hard. (bounces against flipper, against 'ank' targets and sdtm..)
Anything I could do about that?
I already switched the coil with the weaker vuk coil, but that didn't make a lot of difference.

Just measured and some coils get 40 volts, but some (like the sarcophagus) get 72,5 volts on highest coil power.
If I put the coil power on normal, the voltages are 38 volts and 70 volts.
I believe the 70 volts should be 50 volts.

I would love those decals!

Voltage is okay according to my dad. (Peak voltage)
Changed the sarcophagus plunger to a new and slightly longer one, and it solved my problem

On to the next problem: Franks head

Sorry for the double post, but I'm looking for the upper ramp for my Frankenstein machine.
May be dirty but not cracked:

It seems that they are nowhere to be bought
If I don't find one, I will have to reinforce mine too.
My ramp has cracks near the diverters and on the right side where it is connected to the bracket.

Isn't there someone on Pinside who could make those?
I've asked for a ramp on Pinside, Facebook, a Dutch website and a German website and everyone needs this ramp haha.
In the meantime I'll try to fix the cracks.

My game only has 1 other real problem left: Frankensteins head does not work.
The head motion board does not get the correct input from the cpu board.
Connector cn3-1, cn3-8 and cn3-9 on the cpu board should give the clock, data and enable signals but they don't.
Thinking the problem might be the 6821 on 11B (closest to the connector) or a component that is an input for it.
I do have an oscilloscope and voltagemeter, but I could really use some guidance from someone as I'm stuck..
I also asked it in a Facebook group but it did not get me further a lot.
The game plays perfect 100%, except for the head.

Thank you!
But I think my problem is on the cpu board.
What voltages do you have on connector cn3-1, cn3-8 and cn3-9 if I may ask?

Thank you bbaker2824 , very kind
No rush, the game will recieve a full playfield teardown with leds, protectors, new rubbers, target decals and a very good clean so will be looking into that first.

Thanks might do that!

Playfield teardown and clean completed, now I have to wait for the leds and target decals to arrive so I can start rebuilding!
What a difference this is

It should move, mine does not either.
Servo test in the test menu is the one you need.

I completely forgot to write JodyG a message
Just did!

Thanks for the advice!
Unfortunately my issue is on the cpu board haha.
Thinking about shotgunning and replacing a few components

I know they are often broken, but in my game this board does not even get the right signals from the cpu (clock, enable, data) I think.
Do you have a multimeter?
I really could use the voltages on connector cn3 on the cpu

Just bought this to fix the cracks in the ramp.
Hopefully its the right stuff

Still waiting on my leds to arrive so the playfield is still empty..
Can't wait to play it again!

The target decals I ordered look great!
Some of the targets were a bit scratched up so this looks way better

Still waiting on my LEDs, hopefully they'll arrive soon so I can start building again!

Also: Saw the Frankenstein movie the other night and I liked it. Story and acting were a bit weird at times but I'm glad I watched it! The burning of Elizabeth and the ending of the movie sure left a mark. 7/10

I'm not happy with how weak the flippers are, especially after playing for 10 minutes or more. (can't make the ramp anymore)
This is what I did already:
-replaced coilstops
-replaced sleeves
-replaced plungers and links
-adjusted eos
-adjusted angle of the machine to 6.5 degrees
-adjusted coil power to high

Anything more I can do?
The coils in my Frankenstein are 090-5030-00.
Thinking of pulling the coils out of my LOTR to try if it works better. (090-5020-20T)
Or would those be too strong?

Thanks, I tried it but didn't work unfortunately.
I did find something out while looking at the eos switches: the left flipper is the only one with a problem.
Nomatter if the eos is open or closed, I can push it down really easily.
My multimeter is not fast enough to see what voltage it gets though. (Hold voltage of 6 volts is present at all flippers)
Starting to think the left flipper is not getting its 50 volts
Any way to measure that?

Will swap left and right coils today and see what happens.
Thanks!

Update on my left flipper issue:
As I took the coilstop off to switch the coils, I noticed that the actual stop came off..
These coilstops were placed (new) a month ago

Thank you!
Shame these lasted less then a month lol...
Going to message the seller.

UPDATE 19:52= I mailed the shop I got it from that they might have a bad batch laying around. Already got a message back now that they're going to contact the manufacturer about the coilstops as this is clearly not the right quality. Lucky to have such great pinball shops in such a small country

UDATE 21-11-20: My new servo motor is here!
It has black, red and green wires...

Nieuwe servo (resized).jpeg

Thanks @wugly.

So if red is 5v, black ground and green/blue signal, I will need to change the connector just like Guido13 did:
-the green/blue wire should be on pin 1
-the black wire should be on pin 2
-the red wire should be on pin 3
(So switch black with red)

Or am I missing something?
Bit scared to blow the motor up lol

Sorry for double post but got an update:
Switched red and black wires and....THE HEAD MOVES!
Happy that it was an easy fix: only a new servo motor.
How do you adjust the head so it starts in the middle though?

Have to wait on a few leds now and will repaint Franks head and body, and than this project will be finished!

Thanks, found out how it works now
All fixed!

Might be a silly question: how to adjust a lockdown bar on a Sega game? (It is loose)
My Bally/Williams games all have adjustment screws, but this one does not have those.

UPDATE: replaced beer seal and it reduced some of the wiggle.

Frankensteinnnnn...got a much needed upgrade!

Out of the club, awesome game that I really hope to own again someday.
Shame I only have 1 spot for switching games, all the rest are keepers
