Title: Aux Wires on 200 Amp
Post by: WurlieNewbie on November 10, 2019, 04:23:54 PM
Hey guys.  Trying to replace an old noisy amp on my 200.  Can you help identify which of these Aux Output wires is the ground and which is the signal (which is positive and which is negative)?  I've attached a photo.

Thanks.

If wired correctly the braided sheath wire should be the ground.

So the white wire, correct? Thanks.

Should I insulate the other wire with shrink wrap then? It looks very exposed.  Not sure if its supposed to be that way.

The white plastic coated wire is the signal, and the silver braided shield wire is the ground.
The twisted together shield wire is typical - and not a problem provided no stray strands short to some other device.
The signal on this wire is actually an AC audio signal so you may not have any ill effects if it is wired around the wrong way.
