IGT Double diamond S Plus, RESTORATION

[David Walz]

So when I was finished with the job the self test ran a 41 code, the #1 reel is not functioning correctly. I need to replace it.

From an advanced technical perspective it is my experience that computer chips work on smoke.
When the smoke leaves the chip they no longer work and it’s extremely difficult to put it back in.

Yep watch what direction the chips are inserted.

Swap reel 1 with 2 and make sure the error changes to 42, if it is still 41 check the harness wires going to reel 1.

The sockets on the board are marked showing which end has the notch.

The troubleshooting on the error you have been given is solid.

The other thought on a 41/42/43 error is that the error might be pre-existing.
There is a sequence to clear the error. I am not by my documentation but it should be in the flip cards.

Finally in the top corner of the MPU there are 5 resistors.
Each one represents a reel. Typically you see 3 that are well burned and 2 that are pristine.
The S+ can be a 5 reel machine, you change out the reel shelf and harness and obviously glass and chips..
I have never seen one in NorthAmerica and I have never come across a set of chips but apparently the 5 reel versions were quite common in Australia.
If one of the resistors is flaking and falling apart you can replace it from one of the two pristine ones.

Check list for 41 code
Swap 1 & 2 plugs = 41 code
Pull harness check wiring = 41 code
Cleaned the connectors = 41 code
Checked for debris in the reels =41 code

It would be helpful if the directions were explaining the smokey thingamajig.

Will look into it next. I am eliminating the possible failures. So far I have completed this:

Check list for 41 code
Swap 1 & 2 plugs = 41 code
Pull harness check wiring = 41 code
Cleaned the connectors = 41 code
Checked for debris in the reels =41 code

I forgot to reinstall the lock mechanism for the MPU.

[sixcardmark]

Check list for 41 code
Swap 1 & 2 plugs = 41 code
Pull harness check wiring = 41 code
Cleaned the connectors = 41 code
Checked for debris in the reels =41 code

Well the problem is not reel #1 then.

I said that I was a novice not a computer nerd.

Here is the MPU. Is it those in the corrner?

[sixcardmark]

Yep

I just checked out the resistors, I need to replace all three. 470 ohm 1/4 watt resistor. I may have them in my electronics room. Will see tomorrow.
