1.5 amp battery drain!
1.5 amp battery drain!
05, 68K miles.Read some threads on this, but no solution yet. I put an ammeter between the negative cable and post. I'm showing a 1.6 amp drain. The car runs fine. I'm getting 14.3v to the battery while running. I pulled every fuse under the hood, still draining. My light switch is in the straight up position. Pulled the trunk bulb out. No lights on in car/ glove-box. Thank you in advance for any suggestions. Still love this car!!!

I cannot think what it could be but I would try this as well in desperation.
How about some leak at the alternator, unplug this as well.

Re: 1.5 amp battery drain!
WHy did you give up so fast? You are almost there.
There are three fuses in the box next to the battery.
1) 200 amp - feeds the whole car except the starter/alternator cable, and items 2 and 3.
2) 50 amp - Brake Controller
3) 50 amp - Fan Controller
If you yank all three and still have the current, it's in the cable going to the starter/alternator. Yank the big lead off the alternator and if it goes away, get a new alternator (diode(s) leaking).
Otherwise, it's the starter solenoid (not likely).
If it goes away with the 200 amp fuse and you have every other fuse out, then you are where I ended up with Marie's car in north Georgia: there is a flow thru some unfused lead that I did not have time to chase. But I did find the actual wire, there is a junction of high current red leads under the underhood fuse panel. If you have this and find the one that is causing it, leave it disconnected and start the car up and see what is not working, go from there.
