X REG 406 HDI BATTERY IS BEING DRAINED DUE TO SOME ELECTRICAL FAULT. THE ALTERNATOR AND BATTERY HAVE BEEN CHANGED, BUT PROBLEM IS STILL PRESENT. THE FAULT IS INTERMITTENT. HAS ANYONE GOT EXPERIENCE OF SIMILAR FAULT.
try removing the glove box bulb if you have one, and the boot bulb these are out of sight bulbs that you cannot see on (get someone to go inside the boot and watch the bulb turn off)
