on my 95 sonoma i have sirius satilite radio ran to my 12 volt cig liter plug and it keeps blowing fuses. it calls for a 20 amp so i thought maybe i would put a bigger one to keep it from blowing but now its gotten so bad that i cant even get the fuse all the way in before it blows.
If you keep blowing fuses, don't put larger fuses in. Something is defiantly wrong and shorting.
Putting larger fuses in only increases the chance of frying the wiring. So how did you hook up the sirius? Is it hard wired or does it use the cig light plug? Unplug the sirius and put the fuse in, does it blow? I don't see any reson the sirius would pull any power hardly at all. So you have a short somewhere. Have you changed anything in your dash recently?
That's wierd, I've never heard of them pulling that much power. Have you tried plugging it into a nother vehicle. See if it happens there too? Because right now it sounds as if the sirius is bad or has a short in the wiring.
Good luck to you. The only other way it could blow the fuse is if there's already a large draw on the fuse and that pushes it over the edge per say. But the cig fuse only controls the cig lighter/acc. and the OBD connector.
