Ken:
Isn't there something you have to do with dip switches 7 and 8 on switch 1?
MoeJoe7:
I haven't read anything about that, ill look into it a little further. Thanks!
Jim:
make sure the battery jumper J12  is on, this puts the battery into the circuit. the jumper for the ram clear is J10, located down in the right hand corner  of the board, up front .   also look at the number on your mains chips, 92000 or 95000, I THINK (memory) the 95000 you can use jumper to clear, anything else you need clear chips.

MoeJoe7:
Im stumped, 9500 chips, jumpers on 10 and 12, battery is good. Still cant get rid of the 83f code
Badbaud:
Are you measuring the battery voltage AT the RAM?
There is a very thin trace on the bottom of the board that gets ripped up by someone who thinks they don't have to take the board off of it's metal tray to replace the battery.
On the RAM chip itself, lower left with negative DC voltmeter lead, upper right with red lead.
