[W126 Coupe] burned out ignition modules solution

[Richard Hogarth]

Here is a thought, 
The ignition module gets hot and it uses the
fender wall as a heat sink. There has to be a good thick
coating of electronic heat transfer grease on the entire back of the 
module before installing it. If you don't put the heat grease on it,
there will be hot spots under the hotter components inside and they will
cook to death. 
You can get a tube of Silicone heat sink grease at any Radio Shack for
$3.00.
The white grease is made of Silicone oil and a fine white clay.

Subject: [W126 Coupe] powee problem

help! on my dads 500 SEL there was a problem last year where the ignition
control module went bad. changed that with the one from my 500SEC. I also
changed the rotor and cap. well it came up again yesterday. the car wouldnt
start again. I went to my 500sec and took the new one out to put in my dads
car. even though the car had spark at the cap, the car wouldnt start. I put
the new ignition control module in and the car started right up. that lasted
the night and the car wouldnt start again. so what could be the problem? it
keeps frying the ignition control module? help!
