Stereo - no power from battery

In preparation for a new Alpine head unit from Crutchfield (CDE-133BT), I cut out the hack job that connected the aftermarket stereo, the Arb compressor switch, the Arb rear locker switch, and rear work light wiring that I found in the console. I cleaned everything up, bought a bunch of Posi-Locks, printed off the stereo wiring diagram, and re-wired it.

Now, the new head unit won't fire up and I am getting zero juice at the purple battery wire on the truck's stereo harness. What could I have done to the Defender's stereo wiring harness that I have no power there now? I realize this is probably like asking how many zebras are in Mozambique, but maybe someone has had a similar experience? I thought the power wire should always have 12V?

Did you check the fuses? I believe there are 2 under the dash under that tray...

I bought a head unit from crutchfield and tried to install it yesterday. I also have a '97 and my system was stock, so I purchased a vw harness and used it to connect the kenwood I purchased. The tech department was no help on getting the unit to work. I had finally established power to the unit, but the unit would not make any noise. You need to connect the yellow with purple stripe wire, because that is for amplifier power. It should be connected to the remote power on your unit. Once you do that you should be good to go. I do understand you are saying you are not getting juice to the purple wire, which is odd. The fuses are the obvious first look, but I figure that was the first place you looked. Hope this helps you.

When I bought my 97, it was hacked up as well. After a week of messing with the rat nest, I have up, bought a simple relay for ignition switched power and started over.
Really glad I did. Now I know what's what and can make sense of where everything goes.

Purple is "Accessories fed direct from battery via fuse" I would look for a fuse even if it was one somebody put an extra in someplace.

This thread was useful when I replaced my radio:

http://www.defendersource.com/forum/...eferrerid=6091

My harness had not been hacked up, but this still served as an excellent reference. I took the stock amp out of the system and used the Metra 70-9400 harness adapter from Crutchfield.

A note about this adapter: it includes only a single common ground wire for the speakers, whereas the trucks harness has seperate grounds for each speaker. I had some extra pins laying around, so I added the additional speaker ground wires for a clean fit.

Because I took the amp out the yellow w/ purple wire was not used. The new head unit seems to provides sufficient amplification (for me at least).

If you ditch the factory amp be sure to connect up the ground wires that pass through it, to ensure that you are able to communicate with the ECU and retrieve check engine codes.

So it was a fuse. But as Mike noted, not a factory one. I've been removing miles of wire, poor crimping, miscellaneous fuse holders, boxes, etc, etc, etc. I guess this truck had a lot of accessories at one point and the PO hacked into the closest wire he could find it seems.

Bluetooth music streaming from my iPhone 4S and finally handsfree calling. I'm going to add that Alpine PowerPack and that should be enough fidelity for my music tastes. Thanks for the help guys.
