TNC 145 buffer battery help - CNCzone.com-The Largest Machinist Community on the net!

Hi.
My TNC145c control is not accepting the new batteries and is still telling me they need replacing. I have traced 3.6 volts (not sure if this is enough) as far as the plug onto the bottom horizontal board but i am lost after that!
The machine remembers the parameters but not the programs suggesting there is a connection.
Any offers? Anyone got a circuit diagram of the wiring in these boxes?
Cheers
Mike

Might be a dirty contact in the battery holder

As long as it is saving the parameters when you turn it off, clear the error and keep things backed up
