• First 14.8v is a bit high, I don't like to see more than 14.4v. No readings of a draw on a modern car is odd.

    What car is it?

  • Hmm ok that's good to know - hopefully I'm misremembering. It's a 06 Transporter, 1.9 tdi.

    The zero reading thing might be my error - apparently it takes a few seconds for computers to go "back to sleep" after adding the multimeter to the circuit?

    I definitely wasn't waiting very long. Have ordered some test leads with clamps so I can have another go though.

  • Ah, being an older diesel van there will be less things on, no key proximity sensor. But at a guess im thinking looking at alarm, radio or alternator at fault.

    Stupid question, checked that no interior lights being left on.
