Would be interesting to see 5 bright white LED's. Let me know how that works out.

Also, how hot is that 470 ohm resistor getting with these bulbs? Under normal conditions I think that the wattage required was 1.6 watts so
2 watts was marginal to start with and that thing got pretty hot.

I'm pretty sure I picked those bulbs up off of Ebay, so being as they're Chinese, data sheets never did exist  no I was using them on a car radio that had burned out the panel lighting due to a surge.

They seem to work fine, no codes, so there must be enough current to run them. But then, I could probably eliminate the resistor if the cumulative voltage requirement to run them is higher than the supply.

Eliminating the resistor would probably shorten the life of the bulbs though.

Still, drop enough current across a large resistor, wire five LED's in series, and add a diode and a filter cap, it might work. It'd be something to experiment with, all without swapping wiring to the reels.

The resistors check OK, but they seem to run pretty hot. Maybe I should take a closer look at the resistance....

Wonder what would be involved in converting the reader to LED? Seems a small regulator on each reader board might do the trick.

The voltage is AC and the bulbs are in series, each dropping 5 volts.  But now you have to figure out how to wire the LED's in series
rectify the voltage and reduce it . All things considered you may find it easier to modify the wiring and use the 5 volt reader
cards. I have to wonder about the bulbs on your shelf though, if they are all 14 volt bulbs then 50 volts would not light
them up correctly (probably dim). I would need to see the data sheets for those bulbs so that you can see how much voltage
is being dropped across the resistor.

Just as an FYI, the reel reader tester that I built uses 50 volts DC, the bulbs don't care about anything other than voltage.

The bulb is a #680 bulb if they are burning out quickly I would check the 470 ohm 2 watt resistor and would expect to see a rather low value.

Good to seen another machine up and running... Clap

Found the problem; those "grain-of-wheat" light bulbs got me. I had a 41-1 code, swapped readers, then got a 41-2. So I replaced a burned out bulb on the reader. Put it back in, got a 41-1 code, and found a bad bulb on the 2nd. reader. They're burning out like popcorn!

So, I went ahead and replaced all 15 bulbs. Oddly, I had the bulbs on my shelf - I think they're 14 volt bulbs, but were the same physical bulb as the original.

Anyway, all bulbs replaced, game works perfectly. Woo Hoo! 'Nuther one done.

And, thanks to dhellis for finding the bugaboos on the CPU board. All is well now.

 Scratch Head 3200 error I've verify the hopper motor is working correctly and the coins and the wiper\knife free and clear.  Optical Free and clear on the hopper and the door.  After I push the reset and close the door.  Turn the jackpot key I get 00.  If I open the door pushed reset it goes to 3200.  Also tried turning the power off for 5 minutes and same thing I also ran the set 15 chip and I still get the same thing.

CV Slots and Group:

With the help of a trusted NLG pal and my distant cousin, my Fortune Black Jack game arrived last night.  It seemed to be in pretty good shape.  Although listed at mint it needed a good cleaning, door lock, rubber agitator for the hopper and a vent fan door.  I installed a lock and the agitator almost immediately.  The game had over $3.00 worth of coins rolling around in its guts.  I think that I found them all, I hope.   I played the game for a while and it seemd VERY generous.   I am no super balckjack player but I cleaned it out!  No wonder this sucker was mothballed by a casino.  lol. 

Now I have to decide which one of my Bally EM's to sell to make room for the new addition to the family.  Decisions decisions...

what are you using for a clear chip ?
it will display the CNF # on the slot monitor ... but first you have to get to the Hardware setup screen
