Lights working, stiff wheels

No lights on the display or numbers

Power supply cable has the pin 2 like burned, but wires has full continuity

I think I need some help

Show us a pic of the MPU board so we can see the chips.  Turn machine off before removing anything.

The light on the coin comparitor does not light up when the door is open.  It needs a quarter or token in it though.  You are going to need a new power cable.  Try plugging and unplugging it a few times to clean the pins.

I pull out each pin and increased the spring tension, I have not clean them but just figured this works on low AC voltage so I suppose a thin layer of dirty pin can affect? Also unplug and plug several times with no power

Continuity is not the issue. The burn inside the connector creates a weak connection of that ground wire to the MB.

The existing MB power harness on an S+ could very well possibly be over 30 years old.
Why not just buy some new female trifurcon pins and replace them?
All you do is simply cut the tie wraps, remove the harness, cut off the old pins outta the Molex housing and solder in new ones.
It will then be as good as new and last another 30 years!

The pins are crimped not soldered.

Hello RB,

I'm going to check and clean the pins and maybe do soldering to reinforce the crimp, I will test back tonight when I'm back home

I really appreciate the support

Update!,,

Hello members, bee a while but just today have some time for the machine.

After cleaning pins , check voltages and connectors, I have once power on the front digital display, but only in on power cycle doing testing, I have a 61 code.

After that and another power cycle, no display again  corrected found some chips wrong installed.

Now I have 61 on every power cycle, when I press the test button and hold it sounds and show 61 1

Figured to clear 61 1 closing the door and the key

Now figuring out how to continue

Any ideas?.

I really appreciate the support

That's not a b1 or b1-1 It's 61 and 61-1.  When you press test button and it dings and goes to 61-1 close the door and then turn the jackpot key one time and then wait for the reels to spin.  Then insert coins and play.

If the 61 keeps coming back you are in the loop and need to clear the machine with a clear chip.

Thanks for the reply,

Correct figured out was a 61-1

Now I continue with troubleshooting, if I manually add coins with the door open it plays perfectly.

Coin validator has the green light off

When I close the door , everything turns off , do a self test and yellow candle light start to blink

So still work ahead until I can play
