keeps blowing fuse
Hi everyone,
I have had my sirius radio plugged into the cigarette lighter in my '93 for a little over a year now, and have never had a problem. But a week or so ago, it wouldn't power up, so I tried the cigarette lighter itself, and it wouldn't get hot either. So I checked the fuse, and it was blown (as was the fuse in the power adapter for the sirius receiver) So, I ran down to Advance, got some extra fuses, but as soon as I turn the car on, it blows the fuse every time.
Whats the deal? What next?
Thanks.
Adam

You have a short circuit. I assume that this occurs with nothing plugged in to the lighter. You will need an FSM to find which devices are on the same circuit. If the short is there all the time, you may want to try the buzzer method mentioned here recently. It's a crappy job. A lot of time on your head wiggling wires.

I guess sometimes you have to keep doing doing it even though it hurts...just to pinpoint what exactly hurts.
But why would the limit of the circuit be overloaded all of a sudden? It has worked fine for over a year....and then overnight it's fried?
I'm sure a heavy duty auxiliary power plug might suffice as a work-around, but I should be able to plug the standard adapter in with no problems....
ah the joys of owning a 15 year old car with 153,000 miles......so many things just refuse to work. I haven't had operating windshield wipers in almost a year and a half! And no cd player for longer than that.

The lighter fuse is 5 amps. It could be that the Sirius receiver when new drew just under 5 amps, but now that it is older exceeds 5 amps, or it has a serious problem and draws lots more than 5 amps. I would power up the Sirius with an external power supply that has an ammeter and see what the Sirius draws. DO NOT put a larger fuse in the lighter circuit unless you like watching your vette burn to the ground!

Unless my ignorance preceeds me.....am I missing something?
