Trace the wiring start keyswitch to the main board.Replace main board battery. -
Also try cleaning the Ultrex connectors under the operation panel. Very common! =^..^=If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

Hi i think you should also check for cold joints on the operation board.
sometimes the key switch is good but the signal is lost ....
and try clean the ultrex on the dc cont. and the interface pcb.
that's it
keep smiling...
