Help with Aristocrat Mayfair
Hi all, I'm trying to repair an Inca Gold electronic machine.
It had several levers that were bound up with old hard grease that I managed to free up and get the mechanics working.
Now there are electrical issues. The only thing working is the top light, I should be able to get the door lights working, but the rest of the electrics might be a problem.
When I first plugged it in, nothing happened for maybe 30 secs then a puff of smoke from the main board in the top which revealed a burnt resistor. Don't know the size of it.
Any idea where I can get circuit diagrams for it ?

Re: Help with Aristocrat Mayfair
Your machine may be a bit of a late model for us on this site, but post a photo of the machine. We do have Aristo experts on the site and I know one just repaired a four reel with a board. The puff of smoke doesn't sound promising. It's not so much the burnt out resister but what caused it to blow. 

Re: Help with Aristocrat Mayfair
As I said last week .... you'll never get that blue smoke back in.
Post us a photo of the circuit board and indicate the suspect item, there are a few here who can read those do-hickies.

Thanks for the reply.
It's a 3 reel machine.
You can see the hopper type in one photo.
Click on the circuit board and you will see the fried resistor.

Re: Help with Aristocrat Mayfair
Widget will be along soon to at least help I'm sure...We warned him when he fixed the 4 reeler I sold him that he was now the site's hopper king.
These are at the end of our usual date range. Any machine that goes fizz rather than clang is a mystery to most of us. This is one of the last that did both.

Re: Help with Aristocrat Mayfair
Even though it is burnt the resistor still measures 56ohms, maybe that's the right replacement.
Re: Help with Aristocrat Mayfair
Is the resistor fried or is it suffering from a dry solder?
Re: Help with Aristocrat Mayfair
She's fried alright... all of the coloured bands are now black. 

Re: Help with Aristocrat Mayfair
After removing the resistor I took it out in the sun with my loupe and I could see the first band is green so 56ohm will be the replacement.
Would like to know what the circuit with that resistor in it actually does?
Another question: What's the green button for?
When the door is open, there's a momentary green button right up the top on the left.

Re: Help with Aristocrat Mayfair
Might it activate a relay which in turn isolates the mains power within the cabinet?
