My radio went out the other day and I found that the fuse had blown. Whenever I tried to put a new fuse in it would blow immediately. I deducted that I had a short somewhere. I also notices that the number 1 fuse connector has 3 wires going into it. 1 is by itself and 2 are connected together. I took the two connected out and it still blew. When I took the single out it did not blow.... and my radio worked fine! My question is what does that other wire do and is it even worth it to try and find the short. Everything that was working before seems to be working now. It is an old car and a lot of things don't work already. I have the Chilton's manual for my car and it doesn't seem to indicate what that wire does. It doesn't say in the fuse replacement book at the auto parts store. Does anyone have any thoughts/suggestions? Thanks.

Check out your lighter. Mine blows the #1 fuse all the time. I think the tip of the lighter is loose and shorts to the ground.

Daniel -

Is your car a 245, a wagon? Does the rear wiper work?IN my 1985 Wiring Diagram Volvo green book, Fuse #1 powers, the Cigar lighter, Cruise Control, Tailgate wiper, Power mirrors, Radio, and Powertrunk release.

If any one of these has a short to ground, the result is what you got.

You know the radio is OK, what of the other items do you have? If yours is a 245, the rear wiper has leads that go through the cargo door hinges. One of the leads is hot with the key in I or II. If that lead is broken, the wiper may continue to work but it will stop anywhere, not in the park position. If the lead is touching the hinge metal, #1 fuse blows.

That is the most likely culprit. The wires may be visible by looking down into the hinge with door closed.

Re-Post. OK?

Good Luck,

Bob
