[MBZ] And another electrical question...blowing brake light bulb '93 300D

2005-11-19 Thread Lee Levitt
Grrr...

My car keeps blowing the center brake light bulb. Other two brake light
bulbs are fine...this one blows the bulb immediately.

Any thoughts?

The joys of buying a car from someone less fanatical than me. Grrr...

TIA,

The center high mount stop lamp has an isolated (not shared by any other 
lamp) feed from the exterior lamp failure monitor (I think it's N7) so 
that would seem to be the likely problem.


I can't imagine why that stop lamp would blow as there is NO source of 
power with a voltage higher than battery/alternator and that shouldn't 
ever exceed 13.8-14V. That shouldn't blow the lamp in less than a 
thousand or so hours.


This diagram is ALMOST useless to me:

I much prefer this one (go to stop lights):
