Morning campers! I bought a 2004 Boxer 2.2 HDi in 2016, professionally converted to camper in 2014. The parasitic drain varies between 130 and 160 milliamps, I have a brand new battery in it. When the camper is stood still for a few days, the battery goes flat. The offending fuses are numbers 39 (interior lighting-EOBD diagnostic socket) and number 34 (chronotachograph, telephone, alarm, remote control, air conditioning control). I don’t have telephone or air conditioning in the van. With these two fuses removed, the drain is 13 milliamps. Fuse 39 draws about 78 milliamps, but the drain on fuse 34 fluctuates greatly between 35 to 80 milliamps. The split charging system is working perfectly, and the leisure battery has been isolated, so the problem does not appear to come from the camper conversion. Any ideas on what this could be will be greatly appreciated. Cheers.
