JZA70 draining battery.

Simple is always good.

• Have the car off, no accessories or ignition.
• Get your multimeter out, plug the positive probe lead in to the 10A terminal.
• Disconnect the negative battery terminal.
• Put one lead on the negative post on the battery and one lead on the negative terminal. Don't let the negative terminal touch the negative post on the battery while doing this.

This is how much current the car is drawing constantly. It should be fuck all, under .1 amps or even less. If it draws more, you start unplugging shit or pulling fuses until it goes away. Whatever fuse you pull/thing you unplug when it drops is what is draining the battery.

Will have to give this a go..

Cheers, Gav.

Make sure the key is off, the door is closed, and all the interior lights are out when doing this test, otherwise you'll get false readings.

The only things that should be drawing any power are ecu memory, radio memory, clock memory, trip meter memory, and immobiliser/alarm.

My guess is something from the conversion isn't wired properly, and as suggested a relay is staying on.

My money is on your headunit. I had the same problem in the AE82, had no alarm, immobiliser, amplifiers or anything. Power was wired straight to battery.

I cut the wire to the battery - no more problem...
