Parasitic battery drain
Hello,
2000 base model.. 3.8L V6, auto trans.
I've been fighting a dead battery in my car since I bought it. I had it at my brother's for repainting, and just got it back.
I was drawing 0.15 amps (on the 10A scale) before I pulled a 40A fuse in the power block under the hood. The owner's manual says "Instrument Cluster, PCM"
What do I look for next?
Thanks in advance.

Digital voltmeter/ammeter? Can't read 0.15 amps on a 10 amp analog scale. .15 is way too high. The several memories kept alive, PCM and airbags, shouldn't be much over 1/10 that amount, maybe .025 amp. 25 milliamps. What effect did the fuse removal have on the current drain? imp
I agree. 0.15 is still too high.
When I pulled the fuse for the "Instrument Cluster, PCM" the Digital Ammeter dropped to zero. I switched to the milliamp scale and got about 20-25 (If Memory serves.)
