Trying to fix a friends Shaq machine.
The battery setup is causing an issue getting game to start and keep memory.
Old round battery was removed and remote battery with 2 AA doesnt seem right.
Pic below is where remote battery is soldered. I see another positive point, is this in the right place?
At power up it says check battery U6 and check U3. U3 is a chip.
Do I need to change chip out too?

Thanks in advance.
Friends only machine and trying to get quaritine fun for his bored 13 year old son.

Thank you. I did try 3 with no result.
Thats why i was thinking the red wire in pic is soldered to the wrong positive terminal.
Also not sure why there is 2 + points on the cpu board at old battery port.

Some pin wiki research helped a little. Indeed this Gottlieb system 3 only requires 2 AA Batteries to replace 3 volt lithium button battery.
Now myn thought, in pic above of old battery holder the red positive wire doesn't seem to be soldered right on top very well. Wondering if I need small jumper to get to other positive leg above the red wire?
Does remote battery holder wires need to go to both positives?

Thank you forceflow!
No, no visible leakage. The game came with this remote battery. Friend/owner informed me he has to take backglass off every time he wants to play, and press the reset button on cpu.
The remote battery is 2 AA's. I wasn't getting 3v out of battery holder with 2 brand new batteries.
Your idea to be honest, was what I was thinking of doing.
