I recently got a jungle lord and I have a few issues. I have everything up and running but cannot get it to start without going first to audit mode. I do a diagnostic test and the number 0 comes up so I know that everything with the board is good. However, it also will not save my data that I program (free play) also I did the digit test and all my digits work but when I go to play a game sometimes the score is recorded and sometimes it does not. Then when I turn the game off it resets everything and I have to push the cpu diagnostic test to get it back to being able to play and out of audit mode. I checked my 5101 Rom and it seems to be fine and it has new batteries as well. Any help would be great.

Thanks

Even if new batteries, check with a DMM or voltmeter to make sure the standby power is getting where it needs to go.

From PinWiki:
The battery voltage is not reaching the 5101 CMOS RAM (check Test Point TP7, which should measure 4.3v with the power on and 3.9v (or so) with the power off.
Blocking Diode D18 (1N5817) has shorted, and the batteries are trying to run the MPU board when the game is off.

How did you check this?

I am pretty new to all this so I figured if I did the diagnostics test and it said I was good then the 5101 Rom was good. How do I check this?

The only practical way to check the 5101 RAM is install it in a working game.. (not ROM - a ROM is a permanent storage device. RAM is temporary storage. A typical RAM loses memory when power is disconnected. Hence the backup battery circuit.)
If you are going to work on solid state electronics in games, you'll need the DMM/Voltmeter, the knowledge how to use it, some basic electronics theory, some background on the fundamentals of your games specific circuits, and the ability to interpret electronic schematics.

I took my volt meter to the check point and it did read 4.3 v. So I am still not sure why the game does not remember the setting or why it only boots into audit mode.

I did this test here and it works I shut the game off then on again quick and the game went into attract mode. https://pinside.com/pinball/forum/topic/blackout-stuck-in-audit-mode So I think it is the diode. I am not sure what to do though with it?

On top of this when I check diode it is reading proper voltage at close to 5 volts on both sides of the diode.
