I just bought an '87 300D Turbo.Love It! After reading my owners manual through several times I have come to realize my alarm is NOT working.The owners manual say once you lock the car from either the drivers door or trunk the alarm is active.How do i confirm this?I locked the car and waited several minutes,came back and bounced the car at least ten times which should set the alarm off.NOTHING!Is there a "beep" or something that lets you know when it's armed?
The car had one owner.An older German fellow and I am assuming he may have disabled it after inadvertently setting it off and embarassing himself a few times.Every thing is there and all the fuses are good.It just doesn't work.Is there a "trick" I'm missing?Thanks for the help.Joe.
