Have a lathe with a A2100 controller. It sat for several years without being used. It would be hard to boot up sometimes having to be turned on/off several times. We it did boot up it showed a checksum error which told me the WS battery was dead. I changed the WS battery and now it wont boot up and just gives one beep. I look at the error leds on the board we got a green power one so thats good and ive checked the 5 and 12 volt supplies. Initially there are two red error leds on WS fail and RT fail after a minute the RT fail goes out. Ive reseated the sim just in case and that didnt do anything.

Anys ideas of what to try next would be appreciated

Thanks
Geoff
