Just got 2 more sterns last week IM need a lot of adjustments. Is there stronger pop coils for Dragonfist?
2F4E372E-8A30-46BC-BE80-AC1522141086 (resized).jpeg8ECCD93B-7930-47CA-B946-725E5FC34CF8 (resized).jpegACB27E5C-993E-4FF7-BC3C-846E29BA3CCC (resized).jpegB1F3C7AD-8B3D-436F-A35B-F30D3DF364A2 (resized).jpegF086DE05-1269-4764-AE9C-D440478A96EF (resized).jpegQuoted from cottonm4:The manual calls out J-26-1200 coils. I think this is about of strong of pop coil Stern used.
A pinside friend taught me about removing wire from the coils to jazz them up a bit. You could do what I did with my Catacomb with the same 1200 coils to spice things up. Remove 100 wraps of wire from the coil. Or buy some J26-1000 coils from Steve at Pinball Resourse.
Dragonfist slingshots also calls for J-26-1500 coils. Take your J-26-1200 pop coils and move those to your slingshots and put some 1100s on the pops.
That should make in mean and nasty.
I will try removing 100 windings from the coils .
Quoted from vec-tor:I would fuse those two relay/gate magnets...
They constantly burn-up on IM.
May need to change the solenoid/voltage regulator board...
I had the same problem on Stern Freefall.
The CA3081 ic was flaking out.
Ok so this is my problem. I replaced one of the gate coils last week. Now the other coil is out. It was blowing the fuse under the playfield by flippers. With one gate working there is no problem. Both gates working it blows fuse. Some times it works with out blowing fuse. Both gates run off the same relay. Both open and close at the same time. The wires are ran together to both coils. What is a CA3081 ? I replaced rectifier board, I replaced MPU and solenoid boards with altek already.
Quoted from cottonm4:Google that part number. It is some sort of dip emitter
It brings you to Marco. The shipping will be more than the part.
https://www.marcospecialties.com/pinball-parts/CA3081Any chance you have a loose wire making intermittent contact with something else to create a short?
I checked all the wires . Don’t see anything touching. Not sure where that chip would be. Maybe the relay that runs both gates?relay is top right of pic.

I have the original manual in English and German . When I got the game one gate coil was missing. I replaced the coil with a new one that came with the game. I worked about 10 games and then the other coil went out. Few times the fuse under playfield blew. I believe the coil was missing because the guy I bought it from was having same problem and just did not install it. It works fine with one gate hooked up. It as soon as you hook both up is when it has the problem. I would think both gate coils at the same time is drawing to much power.

That would be helpful. Maybe how the wires are hooked up at gates and relay. I have manual if you need any pics of it.
More pics

It looks like that's how it's wired by the pictured relay with the orange-black wire on one of the contacts.
tatman9999, what are the wire colors at the solenoid driver board on connectors J2 pin 8 and J5 pin 7 ? Because the manual/schematics aren't listing the wire color.
Also is the fuse failing the moment the gates switch on or when they are on for a bit?
Did you measure the resistance across the gate coils yet?
it blows right when gates are supposed to move. Right now one coil went bad amd the other gate works fine. Last week the other coil was bad and the other coil worked fine when playing. It is only when both gate coils are working that there is a problem.

I would repin that entire connector, and probably replace the entire housing as well.
They where all repinned
Quoted from PinFixin:Sounds good. I was wondering the same thing about the reflection myself.
I am
Going to remove it tonight and take a better look. It was not repinned by me.
Quoted from dothedoo:I think we’re seeing the reflection of the board on shiny pins. The lettering is almost readable.
Yes I removed connector and it looks good

handle the activation.. Then, only one SDU transistor drive the physical
relay to drive the two gates.
Basically, add a snubber relay assembly.
What is a snubber relay ?
What setting would pick to have the locked balls drain at the end of each game? On Iron Maiden. Or is it normal for the locked balls to stay in the lock? If you shut game off and restart all 3 balls go to apron. This is my settings

Quoted from bluespin:One of the less desirable Sterns in my opinion. But I’ll trade you my project Lightning for your Dragonfist.
I would trade a stern Iron Maiden for another Rare stern + or -
Quicksilver , stars , star gazer
Quoted from cottonm4:Did you get your Iron Maiden fixed with those coils?
I did , another pinside sent me pics. Wires on relay were different. Also replaced both coils . All working now.

Picked this up today to go next to dragonfist, stars, big game , now I need a quicksilver. Star gazer came with 2 new playfields.
