Wiring connection; patch cords?????

Been using the Homemade E-caller for a year or two now. Finally got a Nady 151. Just been trying to use the "search" feature for liitle help. Now I must ask the pros.

Can someone direct me to a link for help?

What cords go in what inputs / outputs? This I think I'm good on this...think the 151 batteries were just crap. Read where Lionho said they were garbage.

Toggle wiring to amp and Nady? I soldered wires off nady terminals.Amp has been running off of 8 AA.

I need to go to Radio Shack today to get parts and replace my patch cable that wires to the speaker.

Thanks guys...I try not to ask any questions and have been on here for over a year.

If I remember right it's
-Rx input to Amp Output
-Amp ext. speaker to speaker
-Use fresh batteries; adjust pots; glue amp dial.

I just need to be refreshed on wiring it all to a toggle(batt. pack, Amp, Rx 151.

Am I right on the above?
 
I'm a little confused by your post.

There are two "patch" cables to my system. (by patch cable I mean two shielded cables with male 3.5mm plugs at either end).

The first of these is the the 48" long Nady supplied one, which goes between the MP3 player headphone output jack and the Nady WLT-15 transmitter input jack. Since this acts as the Nady wireless link antenna, you don't want to shorten it.

The other one goes between the Nady 151 VR-LT receiver "output" jack (not "Headphone") and the amp input. This should also be shielded cable, but the length is not as critical as with the first one.

Speaker and power wires usually won't need to be shielded, but if you have radio frequency interference problems, they may be acting as antennas, and you may need or want to shorten them up.

I don't quite follow what you mean with the toggle, except that I used a push on, push off in-line switch on one of the power pack legs in my wiring harness to switch both the amp and the Nady, so that I could leave the Nady Rx volume wheel at max volume, and not have to switch it off with each use, or pull the terminals off the battery. I also wired in a charging jack in my harness.

You'll want to pay particular attention to not accidentally reversing the polarity to the amp or the Nady. I used a one-way only 2-pin Molex connector on the amp power input to the wiring harness to insure that this connection was foolproof. Beware that it's actually possible to put a 9V battery backwards in the Nady devices, make sure that you wire up any dummy plugs correctly.

Thanks LionHo...I am using the shielded cables that are listed under the Tech section. Just wanted to be sure of all the connections.

Really, I think the wiring of the switch is what I need to becareful of so I don't short anything. I may be making this harder than it is. We shall soon see.

Thanks
 
Lots of guys have put callers together without a charging/switching wiring loom for simplicity sake (though it won't be nearly as convenient).

If you do go with a wiring harness, one leg of the power (+) is all you'd ever need to switch-- it's easier not to mix up the polarity that way. Also helps to always use standard DC coding, i.e. black wire for (-) and red for (+). If you use lamp cord/zip cord instead, get some with a clearly printed stripe on one of the conductors.

And as a final check, it never hurts to test your wiring for shorts with a meter after soldering but before hooking up the power.
