Post by: loudness on January 16, 2018, 09:59:29 AM

Machine has been off for 2 weeks

Turned on machine. Got call attendant error. Opened door, alarm went off, turned reset key to shut alarm off

said ram error, hold test button for 2-3 seconds

sometimes it goes to bios screen

sometimes says ram error

after trying to clear with reset key and holding test button

it goes back to call attendant screen

Do you have the green varta battery still on your mpu?  Check for leaks and corrosion around it if you do.   If it has leaked and corrosion has gotten the best of your mpu, you might be out of luck and need to get a new one, fortunately for you 3902 mpu's are not that expensive and readily available.  If everything looks good or there is no varta battery, perform a clear and setup again, it should clear the error.  You are just stuck on a loop, sometimes that happens, and I suspect your battery might be low since it lost configuration, but you would get the error about a low battery.

Probably that small battery in the upper left corner is low.
A CR2032 and a button cell holder is a good replacement.

how would I check the voltage on the battery while it is soldered on the board?

shut down machine pull out MPU use a volt meter set to 20 v red lead to positive + and black to negative - and you have 2.8 to 3.1 v dc.

You may want to test the battery voltage directly on one of the RAM chips which operate off of the battery.
Black on far right leg of RAM chip, red on Front left leg.

Sounds like you might have to Key Chip the game and go back through the settings.

Yes as Amechanic stated you will have to key and reset your settings. That is the only way I have found to clear coin out jam.
