My jungle lord has been playing great but now it has developed an issue where it boots into audit mode only. You can runt through the audits and it may go into attract mode or it may go back into audit. You run through the audits again and then it will go into attract mode and you can play. Will not hold the free play setting from turning off to turning on. I put original boards back into the machine and pulled out the pinballpcb boards because I wanted to be as original as possible. Any suggestions would be appreciated.

Has batteries. Got to change them out for a coin battery holder.

Original board. Is clean and has had no acid damage

I replaced the battery pack with the coin battery board. The batteries were dead and I just put them in a month or so ago. They were brand new. Where exactly on the cmos do I check if IC 19 is bad. Should I just replace it with an nvram. It already has a socket. The game still boots into audit mode and doesn’t retain the settings

So this is all I would need and then take out the coin battery I installed
