Replaced battery. dead again Dealer said parasitic drain caused by controller not their car. Went and replaced controller with brand new same model. Dead a few days later. Subaru again blamed controller but are looking into it. They say when they unplug controller drain ceases. Thoughts? Sincerely, Very Frustrated

Expert Reply:
It really shouldn't be the controller under normal circumstances. The brake controllers like the Brake EVN # TK63VR go into a sleep mode after several minutes of inactivity which would prevent battery drain. Also the small LED light of the controller wouldn't be able to drain a battery in a matter of a couple days. If the controller is staying active that could be caused by shorts on the wiring of the controller to the vehicle or even a short or corrosion on the 7-way connector.
You could pretty easily unplug the controller for a day or so to eliminate or confirm it as the problem as well.
