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
