Ladies and gents,
I'm in the middle of changing out TVs, both front and rear on our '04 Itasca Horizon 36GD with the C-7 330HP CAT. Now, a small amount of history here. Winne and Itasca, in that era coach, utilized a dash toggle, to switch the make-believe surround sound system in the coach, get sound from the dash radio or, the TV. Well, I've taken that switch completely out of the loop.
The surround sound system, is now a true, 5.1 surround sound with a new, Home Theater/DVD system. I have installed two new, completely separate speakers, to be used for the dash radio only. However, I kept pretty good track of wires and colors for the TV section but, some how, I got goofed up on the wires for my new speakers for the radio.
What I'd like to know is, is there a way to check the ends of the wires, that attach to the speakers, for polarity? That is, which one is (+) and which is (-). On the radio end, they are buried in a loom and go into the back side of a 10 or 15 wire plug, that goes into the back of the radio. So, I cannot get access to that end to see which is a negative wire for each speaker and which is a positive.
So, what I have is, two wires, that are next to each new radio speaker. I have hooked them up to the speakers, and the radio sounds pretty good. I've been on Youtube and all over the net, trying to find a testing method for what I need. But, all I find out is, the use of a small battery to send a signal to the speaker to see if it pushes out or, pulls in, when the battery terminals are touched to the speaker terminals. This does not answer my question. I need to know which wire is positive and which is negative, coming from the radio?
