Hi guys,
Couple of months back I had a short circuit in few wires of my 70 series prado (3-door, 1kz-te). Got the wires replaced, but the battery drains completely if vehicle is shut off for more than 36 hours. I checked voltage of battery and each hour, they go down by some milli-volts. The parasitic drain was only about 12 mA.
I replaced the battery with a new one. Then got alternator checked & got starter motor checked. They are ok too. Battery parasitic drain is still around 12 mA. But again, the battery loses voltage as each hour passes by and after 36-40 hours, it can not start the engine.
I installed a battery kill switch (cutting the negative terminal connection when the vehicle is shut off), and now the vehicle starts even after 10 days of engine shut-off. So seems it IS a battery drain problem, but why can't the ammeter pick this drainage? How to find it?
