Took out radio fuse 7.5 amp and battery drain stopped. Suspect bad load switch need to locate where it is and replace the component. Need help-Swampyankee.( expirienced technician)

 

What radio setup do you have? That's definitely a lot of parasitic loss there. How long did it take to drain a full battery?

 

It has the stock porshe radio and the new porshe battery will drain out within 1.5 to 2 weeks sitting. going to continue investigating.
I bought the car at a Barret Jackson auction not knowing it had an electrical problem. Nice car tho.

If the radio is turned off, it should drain the battery in that length of time. Most of the stock radios use very little battery to keep memory active. I would imagine either you have a faulty radio or something not turning off with the radio like a frunk amp.. which is controlled by the head unit. What model of car? Radio model?

Well, I would encourage you to investigate the situation using a multimeter. That will give you an idea of what is drawing current when the car is turned off. By process of elimination, test each unit on the stereo starting with the frunk amp, CD changer (if you have one), and then lastly, the head unit.

All the best! Hope you find the culprit.

 

Right. Going to do that and unplug components and switches till I find it. Thanks a lot b3Freak
