until you find the problem (if you do), put in a disconnect, works like a charm

 

If the search worked you would be able to see many posts on this topic...I had the same problem twice..got me a battery charger...charged it to 100%....have not had any issues like in one year...despite leaving the stang sit for many 21 day trips...

 

This condition is only with the shaker 1000 amp, not the 500

 

I have the base model single disk stereo that is running an aftermarket amp that IS connected correctly with the remote wire. When I power the car or stereo off, the amp turns off (it has a power light). I have been having problems with my battery since the weather has gotten cooler. If I let the car sit without running for more than 3 days, dead battery. The amp I have has been in 2 other cars anddid not causeany drain on their batteries. I am planning on investing in a Red Top as soon as I bring her out of storage in the Spring. My guess: Ford uses cheap batteries.

 

No, it's not limited to the 1000.

The only way I've cured it is to turn my Shaker 500 off and NOT engage the active anti-theft system. Fortunately, it's in a garage.

 

yeah, id believe you if it didnt happen to my shaker 500. its with both systems, to the extent of my knowledge

 

These car are notorious for dead batteries. Never happend to me yet. Their has been many threads on this. The best thing I cold tell you is, battery tender if sitting more than one week.

yeah you got to turn the car on at least once a week or the battery dies, Just jump it for a bit and you should be good to go
