What are you trying to figure out?

Which do you have? El Dorado or Gold Strike?

I'll need to see a high quality scan of the schematic from e.g. Staples ($2) or Kinkos ($6)

Best order one. You'll have it by Wed.

Hi Playdium
in post-3 You write "the S/M and the BCU is firing constantly" - what is "S/M" ? --- BCU I read as "Ball-Count-Unit" - this Unit has two coils - which one is firing ? Does "firing constantly means": Pull-in and let go - pull-in and let go etc. ? --- or does it means "pulls-in --- pulls, pulls, pulls - never let go ? Does the motor runs while the fault is happening ? Greetings Rolf

So as I look around em tech topics with people asking for help you always chime in with wanting a schematic??? And with options and prices? What gives, I don't get it. Please do explain.

Hi Grizlyrig
I am happy that HowardR asks for (snippets - I need) schematics (I'd like to see) --- prices in Switzerland would be around +/- 20 US-Dollars - the dollar2 / dollar6 I believe is "please spend some money - You make helping much more easyer". Greetings Rolf

Yes, yes, yes and yes. I'll take your use of the word "chime" to mean that you find my posts like a wind chime, that is, not only welcome but even harmonious.

Hi Mike,

Good questions! I've tried to help with phone pic scans and they're always (1) blurry, (2) incomplete, and/or (3) in multiple pieces. Lets say I decide on one or more relays that might be involved. (I haven't decided that) From what he posted I can't tell what those hypothetical relays do or how they're activated. I could ask for more but then when he posts more later, I've been helping others here on pinside or getting on with my life so I'd have to recreate the thought process I had in mind.

Regarding your question about prices, those are economical suggestions to make it easy for the OP.

If a stranger wants my help they should put in a little effort to make it easy for me to help them. If they can't do that then I'm not a good fit to help them.

Which is not to say that nobody should help them. There are plenty of knowledgeable people here who are willing to help without a schematic (you?). And there are plenty of people who are willing to get me the high quality scan that I need, and those people I sometimes even help on the phone.

To each his own!

Here ya go. Does this work for you?

As others have mentioned, it is normal for the TILT light to be lit when you turn on the game.

Does your game have a credit on it? Gold Strike uses a "Credit Hold" (Y) relay for this. It has three switches. One is for the lock-in circuit, one is for the credit light on the apron, and one is for starting the game. If this last switch is not closed, the coin door button will not start the game.

Mine always has tilt on when first powers up btw... also mine’s an el dorado. It was stuck on tilt after transport but I tracked it down to a switch in the backbox that was supposed to be closed... there’s a bunch of them in this game!

Unfortunately, the schematic for El Dorado will not help very much. It’s a replay game with a completely different circuit for the start relay.

As such, I advise the OP to edit the topic and remove El Dorado from the tags and subject.

Now I fully understand what you want. I was thinking you (personally) wanted the scan. I wasn't even thinking of a clear pic or snippet of schematic to be explained in theory.
I certainly do appreciate how you help as you are very accurate with guiding us with fixing the machines.
I think now I may have come across the wrong way( an ass) in my question and do apologize if I offended you as that was not my intention.

P.S. I'm not a fan of my neighbors wind chimes at bed time.

Hey Mike,
No worries. Glad to meet you. I'll pay you ($) later for the excellent setup!
Howard
