Radio Blows Fuse

[texasmike]

I have an AC Delco radio which has been tested at a local repair shop and shows to be in good operating condition with all four speaker outputs working. When I connect the three plugs in the back of the radio, along with the antenna lead, with the key in Acc the 15amp fuse blows when I turn the radio on.

If one of the speaker wires had the polarity reversed, could this cause the fuse to blow? Thanks for any help or ideas.

Speaker wouldn't cause that. If the radio is good, I would look at the power wire going in and ground wire coming out.

If you question the speakers, pull one plug at time for the front and rear.

Thanks, that's what I thought so I will get someone to help me check that out. The truck has been sitting for 14 years with the original radio in it. No one has messed with it so I can't imagine what could have gone wrong with the wiring.

Send pic of connector and wires and, back of radio.

Crossing speaker wires should not cause the fuse to blow.

Did the original radio work? Possibly rodents ate wires somewhere.

The original radio did not work and I found another one on ebay. That is the one I had checked out when the fuse kept blowing. You may be right about damaged wires so I plan to check that out. Thanks.
