Quoted from Noham:I have a Big Guns where I replaced the ram with nvram. The solenoids now firing in attract mode and the game will credit but not start. When the game is put into test mode the solenoids stop firing. Any help is appreciated.
The machine is doing a ball search looking for "missing" pinballs. You need make sure all the balls that are supposed to be loaded in the machine are in the ball trough, and if they are use switch test to make sure all the trough switches are closed that have a ball upon them.
It stops searching for balls automatically when you go into test mode because it assumes you, as the machine operator, are there to find the missing balls and will fix it.
The behavior is expected when the machine thinks it is missing pinballs.
