yeah, there are 3 fuse boxes I know of - trunk, engine compart, near
drivers seat. There are also a number of what I think are relays near
the battery/spare tire in the trunk. I have a MB workshop manual and as
usual, it takes a while to learn how to navigate it. I'm still learning.
re Aux Battery - yep, replaced it with no change. The dash display
shows a battery symbol and something saying it needs to be serviced. I
need to buy a proper battery for the trunk and retest everything. At
one point I had a fully charged battery and all the comfort extras
seemed to wake up and the tranny and everything else worked as they
should - things like cruise control, and some other things I don't
recall at the moment. I haven't been able to spend time chasing
problems properly recently but hope to get a correct primary battery and
check things more completely.
It's a beautiful car and the engine runs great even with the CEL on.
Had that checked and there is a common problem with the balance shaft.
Spoke with two techs at MB and both said the same thing - spending
$3-$5K on a engine rebuild (MB prices). They have had customers who did
have the engine repaired, reinstalled and couldn't tell a difference in
the way the engine behaved. It seems the only thing different was the
CEL was off. SO I'm not worried about the engine. The AT is
different. It has 2 driving modes: Sport and Comfort which are accessed
using a button on the console. Much of the time recently, it was
impossible to change modes. Also, to put it in Park, you must turn the
ign off to remove the key.
Cudo's to MB for extending the warranty +20 or 25 years (!) for the fuel
system. When we had fuel smell they replaced everything around the fuel
tank - pumps, filters, etc.
Let's see, what else? When the AT goes bonkers, it will not shift out
of 2nd making the engine run much higher than normal rpm's. Not a major
flaw IMO but my wife is uncomfortable with such things ;-) Since she's
the primary driver I need to cater to her needs. Anyway, Battery 1st,
then we'll see. But I fear the Alternator may be the reason for the
short causing the battery to drain quickly. But I need to jack the car
up so I can crawl under and disconnect a wire then test for the power
drain before I'll know.

Are there multiple fuse blocks in the 211. This E500 I have i vaguely recall
has 2 or 3 scattered here and there. Also the aux battery can go bad and cause
issues. Yeah, there are 3 fuse locaton

Hi Gang,
I hope all is well? My '06 E350 has been sitting long enough - I need to find
a short. I discovered the battery was being drained. I connected a Test Light
between the Neg Term and the the disconnected neg cable - the light was on full
bright.
I started pulling each fuse one after the other hoping one would cause the test
light to go out. I checked all I know of and none changed the test light. - I
pulled those in the truck, drivers area and engine compartment.
My next step to to disconnect the wiring (B+ maybe ??) on the Alternator to
see if that's the problem. Assuming that tells me nothing, is there any other
circuit checks I can try that might be draining the battery?
I need to test it some more - but it's a new battery, I can charge it to ~13.4V,
disconnect the charger and connect the + & - cables, attach my DMM and I can
watch the V's drop .04v every 2-4 seconds. Last time I checked it, I think it
stopped draining when it go to ~10 Vs if that tells us anything? Maybe it's a DOA?
I'm going to take the battery back to the store and have it tested on the off
chance it's a bad battery. What else can I check and which wire do I
disconnect on the Alternator?
Thanks ya'll, Merry Christmas and Happy New Year!
