Car stereo?

Question

I accidentaly hooked the negative pole on the car stereo to the posetibe on the car battery and posetive on the stereo to the negative om the battery. And now it just keeps on blowing fuses instantly... what could be broken?

Answer 1

Vehicles are design specifically for DC electricity. The stereo has overload protection when going the proper electric path. Backwards not. Some if not all the stereos components are shorted or open because of the large dose of current from the battery. Time for a new one. The same type of thing happens when you do this to the car as a whole. Very unforgiving.

Answer 2

I bet the stereo was blitzed. You might luck out if it had an internal fuse- and if you haven't already opened it up to see, try that. In no fuse is burned out inside, see if any components near the positive wire where it connects to the pc board are burned up and replaceable. The radio is probably FUBAR and fuses that keep blowing are preventing other damage from the car while the radio still is plugged in. Take it out and get another one. Still got the old one? Put it in and see if it will work, so when you replace the one you fried, you have another chance to have what you want that works. Check all the other fuses in the car. There may be more than one fuse box, depending on what car you have. Good luck.

Answer 3

When solid state equipment came in in my trade all the new solid state gear had this written on it in big red letters:

"DO NOT REVERSE POLARITY! DOING SO VOIDS WARRANTY!"

And these types of components cost tens of thousands of dollars.



What happened when you did this was something actually melted in the power supply and now it is creating a direct short circuit.



You can't fix this. It's junk now. It would cost more to pay a technician to fix it than it is worth. Sorry. Be more careful next time.

Answer 4

Do you have a stable ground cable? Are you using the right amps on fuse? Are the cables lined up correctly this time? Check your main fuse box under radio.. and radio itself needs to have a fuse as well, otherwise is too much for radio itself so keeps blowing fuses

Answer 5
