I'm on my third battery in less than one year of owning my 2000 LX470. I've done quite a bit of research and landed on parasitic draw as the culprit. I've used my multimeter to test and have found a few issues.
1. With the vehicle turned off and all doors closed I get around 900 Ma draw (draining my battery in a few days of no driving)
2. When I removed the RADIO fuse the draw drops all the way down to 250 Ma (will still drain the battery, only a little slower).
3. I removed the POWER 40 amp fuse from the drivers side kick panel and the draw drops all the way down from 250 (with RADIO fuse still removed) to 23-25 Ma. From my understanding this is within spec.
The vehicle is stock except for a TJM front bumper. There is a CD stuck in the in-dash CD changer. The door locks only occasionally work. When it is hot outside the lock/unlock will only slightly move the locks themselves (bad actuators I believe).
Am I correct in assuming the stuck CD is causing the majority of the draw keeping the radio "awake" while the bad door locks are contributing the rest of the draw? If so, is there a way to disable power to the locks altogether without pulling the POWER fuse as this also disables the power windows and power moon roof which I like having? I could care less about the power locks at this point. I'm going to replace the factory radio so I'm not concerned with fixing it.
Thanks a ton.
