If you are going to start pulling fuses, wait 45 minutes after you turn the key off or break any electrical connection with the battery. The anti-theft and the ECU/PCM will still be using the battery for awhile after you turn off the engine and remove the key. You will notice on the ammeter that the current will stop dropping after awhile. I've troubleshot some police cars and normal current flow was below .17a. Good luck!

If I leave my radio on my battery will be dead in 2 or 3 days. Turn it off and I am good for about 5 or 6 days. (summer car)

i finally fixed this, hooked up a multimeter and i was drawing 1.4a i pulled the 40amp fuse under the hood for instrument cluster/pcm then troubleshooted some more til i unplugged the amplifier for the mach460 and it went to .3. turns out some others have had faulty 460amps that dont go on standby

thanks for the replies

So how did you fix it?

Do you not have music anymore?

the amp only controlled the bass for the rear speakers...i have a 15" sub so i didnt really need them anyway. i guess if i wanted to "fix" it id have to go get another amp

Thats interesting that it was the amp not going into stby. I'm gonna have to check mine out to see if thats what causes my drain. The weird thing is that my car used to not do it...

That's how mine was, It never did do it until about a year or two ago. Then all of a sudden it just dies after 4 days. I just recently got a new DD and been driving that for the past 4 days, go to get in the stang and of course its dead. .I would try the amp but I don't have the Mach system. I going to try the rear defroster fuse, see if that works.
