Anybody help please?

The aeriel co-ax lead that comes to the rear of the head unit is wrapped in a black casing. It also has a single black wire that runs from inside the casing and ends with a spade connector. This single black wire is not connected at all and I'm am pretty convinced that this is the reason for my poor radio reception. I understand from previous mails that the co-ax block is behind the clock on the right of the dash, I have checked visually and all seems ok but in fairness I have not completely removed.

Before I do this I would ike to identify the single black lead and reconnect it to somewhere just in case.

Gut feel its the supply to the aeriel block, pos or neg though??

Any thoughts anyone.
Cheers
Darren
 
Connect the spade connector to the wire from the windscreen.
I can't guarantee you will get a good radio reception though - it is notoriously bad.

Surely, as it is a black wire, it will be earth ? Nobody in their right mind would use black for the power lead (???). Is the spade connector insulated ? If not, then even more likely to be earth. Hopefully, there will be a male spade connector (assuming black wire has a female connector - should have, but can't really say why I surmised that) on the head unit to connect to.

Unfortunatly not every one in this world thinks as logically as us beleive it or not the black wire in question is in fact +ive!!,it's same on the 944s as well [&:]

The connector is female and it is not insulated but as per Paul's message above I know that I have had pos connections before in black, think Porsche have used brown for neg which defies logic as well. This all added to my confusion. No idea were it was originally connected to.

Paul - you seem pretty positive (pardon the pun) in your response - I will monitor for any further postings before trying at weekend again. Thanks

Can anyone else be sure??

The aerial connection from the windscreen is behind the clock, pull the clock straight out, its on the right. Your looking at a small signal amp, with a co-ax cable connection for the radio. These units suffer from poor earth connection, so find the BROWN wire from the amp and clean its ground point. BROWN, BrowN, bRoWN, what colour? Brown![:)]
 
Don't take my word for it check out 911 Porsche world from april 2004 Q&A section page 112 all will be explained!!

Thanks Paul

I was aware of the amp behind the clock as original mail, it was the black wire at the head unit that confused. Much appreciated

I'm assuming your car has the aerial in the front screen than almost certainly the black lead is the positive feed for the aerial amplifier. It is connected to the switched 12volt output of the head unit. Usually its a blue lead marked "auto aerial" or "remote" coming from the head unit plug and loom assy. If your not to sure just use a inline 0.5 amp fuse to protect it if it is wrong! :( To test if it is working correctly switch to unit to M.W. and tune to any weak station, then by touching the black lead on/off will change the signal strength,( using F.M to test doesn't work because its not amplitude modulated !).
If you can't find a switched feed from the radio just connect it to a ignition controlled circuit. It does the same job. Hope this helps don't blow anything up!
