The RAM sockets for a start but I do have the headers and pins for the edge connector if necessary.
I believe the one I sent you was sealed, on the shelf, and tested good in my E1000 machine.

.....I canâ€™t tell you how many bad cheap ass Bally sockets Iâ€™ve replaced.

One time I asked an engineer why they used such poor sockets on equipment. He told me the anticipated service life of a slot machine was just a few years, after that it is removed from the casino and replaced with a newer model. So they didn't need to use 30 year sockets. The parts of the machine that are built rugged like the hinges, doors, etc are for security reasons, not long-life reasons. When they are sourcing parts to build the equipment they take into account how long the equipment is expected to be in commercial use and buy the parts accordingly. Kinda like not putting Michelin 80,000 mile tires on a Yugo.

I got the idea that if it wasn't for securing the money inside they'd build them out of plastic like a Corvette.

Iâ€™m talking about the ones on the MPU not the ram board. Look at the ones around the ram board. Anything close to the battery can get corrosion from the battery vapors if one was going bad.

I checked the pins on both connectors for the RAM board and they are clean with nice shiny solder connections.
I checked all input/output voltages on all regulators - all good.
I removed the ribbon cable to the I/O board, powered up and still got the 6 error code.
I removed the entire RAM board, powered up and got the 6 error code.
In all these situations, all the lights are still on, for that middle reel board, and that 1W resistor gets too hot.

I'll now remove the MPU and reflow/add solder to everything that looks like it needs it.

Check your software chips, clean the legs clean the sockets, do you have another M1 you can try in the board?

Amechanic · « **Reply #65 on:** September 06, 2018, 02:48:10 pm »

I think itâ€™s his only E Series machine

shortrackskater · « **Reply #66 on:** September 07, 2018, 04:29:13 pm »

My MPU board...
Cleaning, removed all IC's in sockets except three more... had to sleep.
I'll check the last three and plug it in again. Nothing on the back looks like it ever got too hot far as I can see. Is the correct chip in M7?
I don't know if the previous owner messed with this game or not...

Badbaud · « **Reply #67 on:** September 07, 2018, 06:04:28 pm »

M7 looks correct, you should solder a jumper across the contacts (two outside leads) of that yellow relay.

Amechanic · « **Reply #68 on:** September 07, 2018, 08:52:55 pm »

Mark,

This is the relay in question.

Replace C15, 2 uF 25 - 50V

Is the cap C3 the same value as C15.

Badbaud · « **Reply #71 on:** September 07, 2018, 10:01:23 pm »

No, C3 is much larger and is used to smooth out the pulsing DC the Zener diode near it generates.
C15 is the cap for the regulators. A regulator has a tendency to self oscillate at a high frequency and C15 dampens that possibility.
When C15 gets old and dry the regulator can oscillate. I chased that problem on a couple of boards so on any new boards I automatically replace that cap if the original bally (silver) cap is still in the board

Amechanic · « **Reply #72 on:** September 08, 2018, 01:32:48 am »

Ok thanks, yea caps donâ€™t cost much. I donâ€™t remember exactly what happens when C3 goes bad, but doesnâ€™t jumping the relay fix that?

Badbaud · « **Reply #73 on:** September 08, 2018, 05:55:13 am »

Ya, that whole section is not needed for home use.

shortrackskater · « **Reply #74 on:** September 10, 2018, 08:17:18 am »

Jumper soldered in, no change.
I'll do the caps today and post back.

shortrackskater · « **Reply #75 on:** September 11, 2018, 05:15:08 pm »

Replaced C15 with 2.2 uF 50 volt... no change in anything.

Badbaud · « **Reply #76 on:** September 11, 2018, 06:48:02 pm »

Maybe it's time to send me all of your boards?

shortrackskater · « **Reply #77 on:** September 12, 2018, 08:22:29 am »

Maybe I should.
Still do you know why all the lights in my reel#2 board would stay lite? I tried the replacement board and got the same results. Can that be traced back to anything?

Amechanic · « **Reply #78 on:** September 12, 2018, 08:49:47 am »

Mark, Does your game use the beau plugs on the back of the reels for just a guide to aline the reels to the cabinet or do they have wiring attached? Most E-Series just used two molex style plugs on the back right corner of the reels for the wiring source. But I have seen some early ones that were wired like an EM. Iâ€™ve seen coins get in some strange places. Have you had the IO Board off to check behind it? Reason I ask about the beau plugs, I have seen coins in them.

shortrackskater · « **Reply #79 on:** September 12, 2018, 09:03:04 am »

Hmmmmmmm... I WAS wondering that myself and just didn't look and didn't think the obvious that I normally would have! I don't believe there's wiring there but I will check.

I'll report back in a while. Thank you.
