I have a 1999 Honda Civic and I am experiencing a high parasitic draw causing the battery to die when the car sits.

It reads 181 mA and it drops to about 30mA when I pull the fuse for the backup radio in the fuse box in the engine bay.

I have tried disconnecting the ecu and climate control/stereo unit and ran the test again. Still had 181 mA and when I pulled the back up radio fuse it again dropped to about 30mA.

I am wondering what the backup radio fuse goes to and how I can go about fixing this problem?

 

Make sure you have the power wires run correctly if you're running an aftermarket deck. You never said what radio was in the car BTW or whether the wiring is still stock or has been hacked and spliced. That would go under the title of "Critical Information"

 

Your right I found the problem last night it was the backup camera being tapped into the constant 12v instead of the acc 12v. Reason I never noticed was I drove the car daily until we had a snow storm here and the car sat.

Regardless thanks for you help.
