Title: Changing Payout percentage chip on 4th of July machine Post by: RV Doctor on January 25, 2009, 04:49:59 PM I have an IGT 4th of July 3 reel slot and I installed a new payout percentage chip which I'd purchased brand new from a slot company in Vegas. I powered down the machine and put the chip into the "Reel Prom" socket being certain to ensure that the notch was correctly aligned. After insertion I reinstalled the processor board and powered up the machine. The machine lit up and both lamps on the candle started flashing. However the reels did not do their "trial spin" and none of the stored credits appeared on the credit meter. The machine would not accept coins (they fell straight through straight into the tray). I put the original percentage chip back into the machine but the above symptoms still persist. Was I supposed to do something else when replacing the percentage chip?

Title: Re: Changing Payout percentage chip on 4th of July machine Post by: a69mopar on January 25, 2009, 05:15:29 PM do you have a ram clear and a set chip? if the displays are working ok then you most likely need to use a clear and set chip, if the display doesn't work then you need to check the power wire to the motherboard (see pics). This wire can heat up and loose it's connectivity.
Good luck Doc, Thanks, Wayne Title: Re: Changing Payout percentage chip on 4th of July machine Post by: edski on January 25, 2009, 05:31:27 PM The Reel Eprom change procedure is located here.

Are they taut when the power is on? If they spin freely then I'd check the power supply connection that a69mopar posted before trying a RAM clear.
Title: Re: Changing Payout percentage chip on 4th of July machine Post by: RV Doctor on January 25, 2009, 08:23:52 PM Anything on the LED displays? Yes. The "Winner Paid" display shows 61. It showed 61 after I put in the new payout chip and it still shows 61 after I reinstalled the original payout chip. The reels do not do their start-up spin and the reels are taut. Both lamps inside the candle are flashing. Title: Re: Changing Payout percentage chip on 4th of July machine Post by: Brianzz on January 25, 2009, 08:34:31 PM put your new chip back in, when the 61 pops up press the white button till it dings or changes to 61 1 then turn the jackpot reset key, insert coins and play
Title: Re: Changing Payout percentage chip on 4th of July machine Post by: Foster on January 25, 2009, 08:35:33 PM Easy fix for either chip
The 61 error usually means the CMOS RAM does not match the M/B EEPROM. Press the test switch until the machine shows 61 1 and dings Then close the door completely Turn jackpot reset key Machine will reset and spin the reels and be ready to play Title: Re: Changing Payout percentage chip on 4th of July machine Post by: jay on January 25, 2009, 08:40:24 PM Click on Ricks FAQ at the top, the whole procedure (illustrated) is layed out.
