I last drove the car at the weekend.
Long fast drive (140 miles) on Saturday, some more local stuff (30 miles) on Sunday.
I come to the car today (Friday), 120 hours after I parked it, and the remote doesn’t work.
Battery voltage – 0.05 volts.
This is very close to what happened at the end of July here.
I have spoken to the car parts people I bought the 2 batteries off – they have had no other problems.
I am now discussing with some of my more technical friends the construction of a microprocessor data logger to record what happens when I add the 3rd battery this year…
