Sirius radio looking for wiring diagram for sirius sportster 4 satellite radio .........cliff

Buy radio shack electronic contact cleaner (in a can) and spray a small amount on the male connector from the antenna wire, and spray a small amount on the male connector in the base of the Sportster that the sportster interfaces with. Place the antenna connector onto the base unit and remove it several times and swirl it while connected. Place the sportster into and remove it from the base several times. This usually will fix the issue. Sat signals are extremely sensitive to the slightest oxidation or dirt or whaterver on that tiny antenna connection point.

Shouldn't need one. Does the rear antenna connect to the direct FM box?

I'm afraid those things are throw away items. They cost more to repair than they cost to get a new one.

You can get a new dock and remove the piece off the Sportster yourself.

My wife replaced the car kit.
The sportster itself was fine, what fixed the problem was replacing the cradle.
Now the second one has taken a dump.

Not advised. They have different resistance and are set up for different Sat signals. Chances are you will decrease the life of your radio if you get a signal at all.

you have a live going to ground meaning a live wire is touching another wire or touchin the caseing thus blowing your fuses

I work for sirius so I know about all of these different issues and the most common one is the connections. It is imperative that the radios be connected to power with the cig lighter adapter. This adapter had circuitry in it that lowers the cars 12 volts to 5 volts which the sirius unit ooerates on. The old units were 12 volt and could hard wired into the vehicles fuse block, but all of the new radios operate on 5 volts. If this is not the issue with either of you then you have defective units. Being that all warranty replacement are with remanufactured units, your chance of getting a problematic unit increases after the initial return of your new unit.

Look at the bottom of your unit, you'll notice the round port next to the slot? It get's jammed up inside the unit if you pressed to hard setting it into the cradle at some point. Not easy to fix, unfortunatley.

sell it or so many of the units run into this problem and nobody knows how to fix it.

yes, some sirius radios work on 5 volts, and some work on 12 volts. Your sportster replay is a 5 volt unit. If you trace that wire back, you will find a cigarette lighter plug with a transformer built into it, with either wires soldered to the terminals, or a female cig plug wired up behind the dash. Whatever sirius unit you plan on hooking up, I strongly reccommend using the transformer that it came with......however if you're willing to take a chance, it's most likely 5 volts.
