Do you know where this ground wire attached

[Radio Fixer]

I am working on 1974 BMW E10 -2002.

I am not sure if is part of Heater box, Bear AC, or wiper motor. I do not remember which one and the location that is attached.

It is definitely a ground connection. It is about 5 inches long and about 1/2 inches wide, it is covered with black insulation from factory. 

Please see the picture attached.

 

Thank you and have a good weekend.

Regards,

Jay

The heater box ground on my car is a small braided strap.  The wiper ground is a straight brown wire.  I don't have AC, so maybe part of your Bear "Behr" AC?  I've disassembled a lot of these cars and never seen a factory ground strap like that one.

Having installed more than a few Blaupunkt radios in my brief career as a parts guy at a Renault/Peugeot dealership, I remember just such a strap as part of the extensive installation kit thoughtfully provided by the German makers (long before Blaupunkt outsourced their radios to Japan).  If not for the hood, somewhere else on the car as an anti-static ground--even the radio chassis itself.  There was also a condenser to be fastened to the alternator's B+ terminal.

So THAT'S why a few alternators have that!

 

I always wondered, because it seemed period, but also not all that common, and not 'factory'

but NOT aftermarket, either.

 

That said, a condenser on an alternator output's not going to do a lot of noise suppression.

It'd work a lot better on a generator's switching noise...

 

t

would suppress the slip rings, tho.
