Title: Battery Post by: am4bama on July 12, 2013, 09:11:52 PM The small round 3 volt flat battery on the 3902, tests 2.7 V. What does that control and can it be replaced without resetting?
Title: Re: Battery Post by: brianfink on July 13, 2013, 10:58:19 AM This is your RAM or CMOS battery when it getts to low you will get main battery low error. You do not need to do a ram clear, it will do a partial clear when you remove the battery, just turn your jackpot key and follow the on screen instructions to clear the RAM error.
Title: Re: Battery Post by: am4bama on July 13, 2013, 12:34:16 PM Thanks, will go ahead and replace it.
Title: Re: Battery Post by: azgamingslots on July 31, 2013, 04:34:25 AM since a new battery needs to be soldered in, replace it with a battery holder, so future changes only involve slipping in a new coin cell.

It is a 3v coin cell either in a clip holder or soldered on. Of you can't do it yourself and have a Batteries Plus close to you they can do it for you

But I going to take a look ! Thank you Title: Re: Battery Post by: azgamingslots on September 17, 2013, 07:24:52 PM a 2.7v battery will definitely give you a low battery warning, and will haunt the game until you replace the battery,
however, if you're having trouble finding the cpu/mpu, probably should have someone else look at the machine, -you can really do some damage if you don't know what you're doing, find a computer geek to help you with the battery, busting your soldering cherry on an expensive board isn't recommended -a misplaced drop of solder or overheating board with the iron can cost you the cpu board. maybe you can find some instruction on you-tube etc. ALWAYS POWER OFF MACHINE BEFORE TOUCHING ANYTHING INSIDE MACHINE!!! removing boards etc. with power on can/will damage the I/O board(s). Title: Re: Battery Post by: Stacie on September 17, 2013, 08:58:30 PM Thank you! I think I found it . I was very careful and I did have the machine shut off and unplugged. I'm going to batteries plus with the board tomorrow ! :) Thank you so much! Hope this fixes her :)
