Quoted from skquinn:"Adjust Failure"
From recent experience with my system 11. Adjust Failure means your battery is dead. Or, acid has eaten away a few solder joints. As well, the pads on your battery holder could be shot or even missing. As well, a resistor located near the battery holder could be blown.
Some very good troubleshooting: http://techniek.flipperwinkel.nl/wms11/index3.htm#factory
