[W126 Coupe] Relays

[Mike R.]

I'm not sure about a Euro. US cars are required to have the windows dead
with the key out of the ignition. If this car is in the US, it was supposed
to have been converted, i.e., windows disabled with key out. 

 

Can anyone else with a Euro SEC on the List tell us what is supposed to
happen? Do your windows function with the key out of the ignition?

Mike, thanks

My windows work with the key out of the ignition and relay in place......so
you figure my ignition is on its last leg somehow?

What year is the SEC, which model (e.g., 380, 500, 560)? Normally I would
just look it up on Members Cars but Uncle Satish hasn't posted anything
there since forever.

 

More below after your questions.

Hi all,

Tell me something about relays, please.

 

1)What does it mean if one heats up when left plugged in..... - it is
energized (contacts closed)

   a)When I unplug it, the windows and sunroof dies.         - sounds like
it is for those components and it is doing what it is designed for.

   b)If I leave it in the battery dies if the car is not driven for a week.
- something bad somewhere else in the car that is keeping that relay
energized. My first guess would be the ignition switch since most 126's have
the windows/sunroof disabled (off) with the key out of the ignition or "off"
See if other electrical things work with the key off/out. 

 

2)How do you trouble shoot a faulty relay and FIX it? - see above, I don't
think it is a bad relay.

   I can't find one of those 1"X1" relays anywhere for sale.

 

3)I presume it is a circuit that is stuck open ...or shut inside the relay,
depending on your point of view.

or......a short circuit in the wiring to the windows or sunroof somewhere
that keeps power on and heats the relay, which doesn't make sense as
something would burn up eventually.....like my nice SEC

 

4)I look pretty stupid going to the Mall and having to open the hood to take
the relay out and then to return to replace the relay so that I can open a
window.

People look at me and I just say: "don't want anyone to steal my nice SEC,
so I take the on-star starter ignition control booster module with me.....I
can then turn the car off with my celphone if someone dares to steal it" 

 

Gets everyone going , snicker snicker

 

Hein PS Why did the administrator sensor my post of this morning about the
gangster mobile?? No, No uncle Satish - if you tried to post a picture over
100K in size, this system will not let it go through.
