New to a motorhome having previously owning and building my own campervans. Purchased a 2013 auto trail apache , used with no electric hu for the bank holiday fri thru to mon with no issues but this weekend after having new stereo head unit fitted the leisure battery drained .the head unit is fitted to the leisure battery on this auto trail apache so i Changed the set up to totally isolate has found out the head unit was still running .the ? on the Sargent ecu 300 unit above door is showing a voltage drain of approx -1.7 amp when everthing is turned off ,spoke to Sargent and they said it is normal but was wondering if others have the same reading ? Sargent have advised to do a re-set( re calibration) if it hasnt been done for a while .
