The Sirius reciever is 12 volt

 

NOT TRUE. Some may be, but the Starmate 4 I bought recently has a small transformer built into the cigarette power cord. 12v into the cord, but only about 4.5 volts actually to the radio. 12v will fry the radio. before you automatically put 12v to the radio, check out the supplied power cord to ensure it isn't stepping down the voltage.

 

This has sure been a learning experience. I am amazed at how much information was available on this topic, and how different the information is. I also appreciate everybody contributing. I am mechanically skilled, however, when it comes to electronics I am a novice. My Sirius Receiver is not a 12v unit, it is 4.5. I did hook it up directly (12v) and it did not fry, or blow any fuses, it just would not go on. Then I hooked it up from the same power source (the additional light hookups for international models) through the cigarette lighter adapter and it worked. I tightened, taped, and tidyed everything up, tucked it under the fairing, double checked that everything still workedand called it a day!!!

 

Like with anything else, sometimes ya gotta double-check stuff. Can't count the number of times over the years I "presumed" that something was one way, and found it to be different!

 

Well I read this thing three times and am still baffled. If I ever want to do this, which I was thinking about, I will offer lunch for the help.

 

Anytime, mah friend........you ride w/Gruene HOG??

 

Well, technically it can't be a transformer since they don't work with direct current. "Voltage divider" would be a better term.

 

I was thinking about riding with Gruene hog. Cowboys is a little far.
