Re: Dead battery
I am not in AA but my rescue people had the bit of kit on board to test the alternator but not the 'drop charge' test.
Can't remember where it was posted the other day (might have been on my post in the GTV section "bad day, 2 new problems"!) but they basically said get an ammeter and stick it on the battery and look at the reading, then, one by one, take out the fuses and look to see if the reading changes, where you get a change is probably where the problem is. i.e. if your reading that it is losing 1 amp and then you pull the headlight fuse out and it goes to zero amps then your problem is there, I think!! I presume you need to do it with the engine off as you are having the problem when leaving it
Deserted the marque, nut not for long!
