Re: {Chrysler 300} Car draining from Stereo system

[John Grady <jkg@xxxxxxxxxxxxxxxxx>]

You are correct , one of their devices is installed wrong . It is intended to be switched with ignition—- they have it on the battery . Or it is defective and not turning off . 

On your chrysler it is not really ignition —it is ACC on fuse block —-not battery . ACC comes on with ignition switch , things like heater fan and radio . BAT all the time on. 

They wired it wrong .

They may need a fused relay powered by ACC terminal to switch on their power 

Direct from battery through that relay  if a big system . There is one small almost no drain wire for radio memory that goes to battery . They may have swapped that with radio power wire . 

For sure : 1) installed wrong or defective audio  component 2) your alternator is fine . Alternator has nothing to do with battery going dead while  car sits. Obviously true . 

Insist they reinstall power circuits correctly , or tell them you are going to another shop and will sue them for what it costs to fix it .

As you say fine before they touched it . Check out ratings on google etc

Sounds like the isolator is not installed correctly. I assume they used one for an RV so it will charge the auxillary battery while you're driving.

Hi All,
John Grady that is exactly what happening now, my car sits and the battery drains.
First Stereo install, the base would flicker but not drain the battery. Then the shop put in a battery in the trunk with an isolator- that’s when the battery started draining. The amps in back are running through the battery in trunk which is not drained. The music shop and the “parent” shop checked all with the meters, disconnected the stereo, isolator and alarm system from the main battery and said something is still draining so it couldn’t be the music. I reminded them that my car was not doing that before I brought it to them! I’m pissed but don’t know what direction to go in?
I have a beautiful 1967 Chrysler 300 convertible now sitting in my driveway and I’m pissed!
