Good afternoon again.

I attached all the information on your seat to your previous post.

As far as the draw, how many milli amps is the draw? Did you unplug your amp and see if it went away?

No, the harness is in the center console. I did remove the fuse and the battery is holding up now of course the radio does not work.

Okay, unplug the radio and install the fuse and see if it still happens.

I have taken the radio out and put the amplifier fuse back in and after letting everything go to sleep I am not seeing and voltage drain on the amplifier fuse. What would be the next thing to do.

If the fuse is holding, turn the key on and see if the fuse fails.

If it does, then unplug the amp and retest.

If the fuse holds, the radio is the issue.
