Bought Air man compressor a couple of years ago and has accompanied me on a few euro tours. Luckily never really used it in anger for bike. Works perfectly well and use on car etc from time to time. Went to use on K1300S last night as going away for a few days. Plug into socket and tested ok for about 4 seconds. Unit then does not work, is this a symptom of the CANBUS system or is there something im missing. Should I install separate socket direct from Battery to resolve
