[W126 Coupe] Please Help, alarm issues..

[Jim Ham]

If you have removed the radio this will set off the alarm. In my car ('85) 
there is a leaf spring that presses against the radio chassis to sense it's 
presence. If it's grounded it assumes the radio is there. I'd try a clip 
lead to ground while the radio is missing to see if this fixes the alarm 
problem.

Jim Ham
