Son in law has a 51 plate diesel Galaxy which seems to loose the battery charge after being left standing for 4~5 days. It had a new battery last year, and the recent cold weather may be a factor too. We tried measuring the current drawn when standing idle and it's all over the place, generally between 0.08 to 0.24A tried a different meter with the same results. We pulled out most of the fuses in the dashboard box one at a time to attempt to find where the current was going but no joy.
Now I assumed the current draw would be pretty constant when everything was turned off, running the clock, alarm, immobiliser etc. but this is constantly changing, showing over 2 amps on occaision. Have I assumed wrongly (as usual?)
Thanks
