Dead battery, -w- removed CD changer
Ahoy, Mercedes Folk,
Here is an interesting – ‘happening’ with my ’06 S430, which involves a dead battery, and a (removed) CD changer.
My CD changer failed, so I removed it, to install a replacement, but it was bad, so I just left the CD changer out. Next day, a dead battery, so I replaced the (original battery). A few days later, the new battery was dead.
Charged, checked loads, and found ~~ 6 amp drain. (Later) learned that it takes a while for things to shut down, but within maybe ˝ hour, should be ~~ 50 milliamps. After an hour, found 2200 ma drain!
Car into a very good shop, who did LOTTSSAA tests, (see below) and they finally asked for the old CD changer, which they re-installed, and car is now OK. New problem in their experience.
I have long noticed that a modern car can be TERRIBLY offended by someone poking around under the hood with a screwdriver. I guess that this car ‘missed’ being complete, and this was an act of ‘retaliation’!
Enjoy /s/ Bob
