blaupunkt radio speaker feed question

[scotts90ranger]

ok, so I had some crappy wiring in my truck for a while, some electrical tape fell off of a splice and shorted a speaker wire to ground, which seems to have overloaded the right side channels of the radio, they no longer work, left side works fine. both the front and rear speaker do not work anymore, if it matters, it was the rear that was shorted, the splice was corrected yesterday when I soldered and heat shrinked the two....

the radio is a Blaupunkt Miami Beach from around 2003 (I can look it up if it matters), is the thing fubared? I haven't tore into it to see if it is just a resistor or something, figured I'd ask before getting too far

Hi I'm not a car stereo expert or anything but have you looked at the back of the stereo to see if there are any fuses going to it if so there could be one for the left channel and one for the right if not you probably did blow a resistor or relay on the inside. Hope this helps

The fuse should have killed everything though, not just the one side. It is worth checking out though, but I know my Pioneer's only have one master fuse.

Also check the fuses in the cab as well. The deck might be hard wired into the ignition or something instead of the proper way.

Is the balance control set properly???

Usually when an output in a radio goes, all the channels go not just the right side. Using a volt meter (DC setting) check the voltages on the speaker wires. Yes, I said speaker wires.

With the radio on, you should read 1/2 of battery voltage or about 6 volts on EACH speaker wire. Each wire should read within a tenth of a volt of each other. If this is the case then the output is OK and the problem lies on the input side of the output. Unless your an electronic tech, I'd quit at this point.
