Well I've had the car now for about 9 months now and ever since I had the car I've had a some kind of a battery drain. When I first bought the car I immediately put in the RNS-E and OEM Bluetooth along with the added Phatbox & Sirius tuner.

There was a problem with the RNS harnesses that were being made which had the AMP turn on located in the wrong spot and would cause a battery drain. I've made sure that my harness didn't have this and it was located in the correct pin.

How or what can I do to find the culprit? It's very weird that I can let me car sit untouched for 2 weeks and come back and it will start absolutely fine. But I'll drive it for 2-3 days after that and then let it sit for the night and once again the battery is dead.

This has happen on quite a few occasions since I owned the car. I really can't take it to the dealer for this problem becasue my dealer is a real butthead about modifications and they won't mess with this. I'm not sure about that for sure but I really dislike them even putting air in my tires.

Any help or recommendations with finding an answer?

Granted quite a few of these are a direct result of disconnecting the battery.

to disconnect the negative terminal of the battery, and connect a multimeter set to measure current between the battery post and the cable. This will allow you to see how much current the car is pulling from the battery.

Then begin pulling fuses, one at a time, until you see a substantial drop in the current. That way you should be able to identify which circuit is producing the drain and narrow things down quite a bit.

If the battery is going dead overnight, you're looking for a whopping drain, probably in excess of 1A. This should be very straightforward to find using the method above, except that it's obviously intermittent.

Except possibly the intermittent data-bus problems. The Telephone module for example, is commanded to powers up or go to sleep via the data-bus; there's no traditional Terminal 15 input (switched +12) input.

ground wire for the OEM bluetooth module. I had the spade plug connected to a bolt but it wasn't even tightened down at all. I must have just completely forgotten to secure it.

Do you think that the telephone module has not be operating correctly be not letting the RNS-E power down correctly and draining the battery?
