BE1432 Install Help
I am having trouble getting sound out of the Becker 1432 in my '92 400E. The head unit gets power and tunes, but there is no sound from the speakers.
Here's what happened:
The original head unit had gremlins that made it randomly attempt to eject a cassette when none was present. I finally had my mechanic just disconnect the head unit, and I lived without a stereo.
Eventually I purchased a new head unit on eBay. I've attempted to install it, but no sound comes from the speakers. It powers up, displays, tunes, and even the antenna reacts to my turning the head unit on or off. Just no sound.
I reinstalled the old head unit and got the exact same behavior.
In installing the head unit, I am connecting five connectors. Looking at the rear of the unit, left to right, they are:
- large, round din-8 databus connector
- squarish security connector with auto-disconnect clip
- black rectangular five-pin connector
- black rectangular four-pin (one pin offset) connector at the top right corner (battery, ignition, etc.)
- small lug connector for antenna at bottom right corner
These can be seen in the image below (which was originally posted by Scott of La Jolla Audio in another thread).
Does anyone have any idea what I could be doing wrong? I know I could be barking up the entirely wrong tree, and the problem could be in the amps or pre-amp in the trunk. That would be a big coincidence, though.
Any help would be gladly accepted!
Thanks,
Ross
