BACKLITE LIGHTS ALL OF A SUDDEN STOPPED WORKING

[coorslight115]

while we are all here and on the same page...does anyone have the pinout for the harness that goes from the B/L controller board to the Cab i/o. Might come in handy here and I could use it too....sorry to hijack the thread.

That's what I was thinking. It's not that bad to swap though. Six plugs and 3 clips after you get the reels out, could be worse...

look at the disaster of wires lol where do i begin.....

[stayouttadabunker]

Check the ones that go from your bc to the reels.
Wiggle the harness with the power on and watch the reel lamps.

[staz]

i wiggled them nothing..... could it be the bc ant getting power at times

[stayouttadabunker]

Could be an intermittent P.S. too.

[staz]

what does that mean?

[stayouttadabunker]

Power Supply could be going bad...

I still think it's just a loose receptor pin in the harness though.
You seemed to get life into the lamps after every bc change.
I'd be wiggling those wires too - while watching the reel lamps.

[cowboygames]

If it was a bad PS he'd lose more than backlit reals I would think. Bunker's probably on the right track

[staz]

which plugs on the bc controll the lamps?

[stayouttadabunker]

The 14-pin and 10-pin Molexes on the backlit control board control and power the lamps.
If you pull them off the board, the game works fine - just no lights though... 

The 14-pin Molex powers the lamps for reels 1-3.
The 10-pin Molex powers reel lamps 4-5 on a 5 reel machine.

[staz]

whats the 4 pin molex for?

[stayouttadabunker]

whats the 4 pin molex for?

Power for the bc board.

[staz]

so pretty much my problem could be either molex harness..... i might have to get a whole new harness

Hardly...all you need to do is find the cuplrit receptor pin and bend it with a needle.
This way it will "grab" a male pin better.
Have you've NEVER seen all the posts on "De-Oxit" de-oxidzation spray ?
Go to Radio Schnack and get yourself a can of it and spray it into the Molexes.
Let dry then wiggle the plugs back on.

For now though - you can get by by pushing the wires from the back of the connectors into the housings.
I'll bet you pulled one out of the connector housing ever so slightly.
Most people pull on the wires instead of the sides of the housings then report that something's not working.
In your case, somebody could have pulled on the wires a bit and wiggle one loose.
Since you're the only in there - my guess is that it's you....

Since you have a 3 reel game...I'd really inspect  the heck out of the 10-pin Molex.

Last week we had a guy crying all week his machine wasn't working
when it turned out that he was messing around with it and bent a pin.

[staz]

well its working so far so ill leave it alone till it happens again...... i was trying to understand what everything does.... the harness that connects to the io what does that do? also what does this part do? im learning slowly lol.....

[cowboygames]

The harness to the cabinet IO is the interface to the mpu and controls the backlighting. Your picture is the mpu to sas interface I think
