Those ramps should come down during any fights. Start a fight and see if they come down

Manually ground the transistors that control those coils and see if they work.

I was helping a Pinsider out earlier this year with the same problem..which I think was in your area. The last communication I had with him...and from the pictures we exchanged...it looked like both coils were wired backwards. He had mentioned that the game ramps never worked since he got it.

Check the wiring on those coils. If I remember correctly they are 3 lug coils. If they are wired backwards..you probably took out the transistor also.

Probably the same guy.

Here's how the ramp coil works:

There's a high power side of the coil..that lifts the ramp. There's a switch to tell the MPU if the ramp is down (switch closed = down). Once the ramp is lifted with the high power side of the coil..and the switch contact is broken...the hold side of the coil should take over. Just like a flipper coil. I think the center post also used the same coil

My best guess is the reason you are seeing the little 'twitch' is because the high power..and hold wires are reversed. The 'hold' side would have enough power to move the ramp slightly..but not extend the ramp all the way up

I think he might have fixed the wiring..but not the transistors?

Another possibly is the switch on the coil is bad...plugged into the wrong spot..etc. It could be telling the MPU the ramp is already up..and only firing the hold side?

Hopefully today I will check out the wiring again and post the results. I do appreciate all the help from people who I hardly know. I am not handy with a multi-meter. It has been a busy last two years and still getting bad news about a close friend. I am looking forward to getting everything back on track and enjoying pinball and my life again. Chris has been a great help and if MB is the guy I contacted in the past from Long Island I do appreciate your help as well. The next couple of days is going to be busy and I hope I will have some answers to a lot of things.
Thanks

After last weekend being so busy, I finally can post a few pictures of the left and right coils in my machine. Looking at my coils compared to the other coil posted, my coils look like they are missing a spring(s) and look upside down(reversed). Where the coil wiring is on the other coil compared to mine does not look correct. Can those springs get ordered?

I will check that out hopefully tomorrow, but look at Monster Bash's coil picture compared to my coil pictures. His coil has a spring between the "c" clip and the wires attached to the coil. My coils are missing the springs in between "c" clip and where it is wired. His coil in the picture looks like it is reversed compared to my coils and the three wires are at the opposite end of the coil compared to my coils. Not 100% sure, but looking at the diagram in the manual on page 2-30 I think the coils are reversed, missing the spring and the first and third wires have to be switched once the coil gets flipped and a spring installed. The guy that I bought the machine off of before me must have replaced those coils, left out the spring(s). I must have never paid attention to the left and right ramps not working in the middle of the fight section of the game. It's late and hopefully tomorrow I can work on it. In the diagram it shows a two wire coil, but it is supposed to be a three wire coil, but the part number for the coils match. Thanks Chris.

Yeah.. looking at the pics there's a few things wrong..I think you nailed them all

-Missing spring
-Coil installed backwards
-Brown wire and red wire reversed

Yeah!!!!!!!!! Finally fixed the problem. Reversed the coils to the right position, switched the 1st and 3rd wires on the coil, added new springs and the ramps work perfect. I ordered new switches that I did not have to use. The old springs were squeezed between the bottom of the coil and the bottom plate. You can see the old spring in one of my pictures that I originally took. Thanks for everyone's help.

Atta boy!

Now go punch someone in the face!

Nice! Congrats on fixing the issue
