LC III: Battery +ive side: What chip is it connected to?

[Stephen_Usher]

I've got a battery damaged LCIII almost completely operational.

The original battery holder (long gone) has been replaced with a CR2032 with the positive side connected to the remains of the + connector for the battery holder. However the system isn't holding its settings.

Unfortunately the Bomarc schematics for the machine totally fail to show where the positive side of the battery is connected.

Can someone tell me which component the positive side of the battery should be connected to so that I can run a bodge wire?

Thanks
