Hi, Purchased new battery about 6 months ago other knacked. Haven`t used car for a few days and battery totally flat. When driving at night if I switch rear screen or heated seats on ignition light glows faintly. I`ve taken the following readings and could do with some advice please.
IDLE=12.96-99v
2000RPM=1301-02v
FULL LOAD @ IDLE=11.99-12.02v
FULL LOAD @ 2000RPM=12.09-12.11v
I`ve let it run for 20mins and the earth connection on the battery doesn`t heat up. Would it be the alternator and if so are they on TC with VX or is it better to source elsewhere. :-/ :-/
It has happened only once to me, but I was driving along and suddenly the radio cut out, the lights went, and then the engine stopped.

When the AA turned up it was found to be the alternator which was no longer supplying power to the system, so the battery took on the full load without any chance of replenishment and then gave up exhausted!

So in your case a similar thing is happening and my conclusion is that it is the alternator. Just check first though that no leads have come loose.
Best of luck
