How do you know if your car radio is blown?
Keep your ears (and eyes) open for some of these issues:
- Distortion at Medium Volumes. The hissing or fuzzy sound of distortion is a common sign of partially blown speakers.

- Lack of Range.
- Rattling and Popping Sounds.
- Car Radio Isn’t Working.
- Infinite Impedance.
- Repairing Minor Damage.
Why does the time in my car keep changing?

Can I connect red and black wires together?
These wires are typically used for switch wiring as well as the interconnection between smoke detectors hard-wired into the power system. You can link two red wires together, or you can link a red wire to a black wire. Since red wires conduct current, they are considered hot.
What color wires go together?
See Table below. The protective ground is green or green with yellow stripe. The neutral is white, the hot (live or active) single phase wires are black , and red in the case of a second active.

How can you tell if a relay is blown?
Using a multimeter to test a relay fuse is pretty simple. Set the multimeter to Ohms and touch the leads on the electromagnet coil pins to measure resistance. It should be between 50 to 120. If it’s out of that range or says it’s open, you have a bad electromagnet coil.
How can I tell if a relay is bad?
You want to feel and listen for any clicks. If you feel and hear clicks, the relay works on one side – the side with the energizing circuit and coil. However, if there was no sound from the horn, the relay has a problem along the contact circuit.
What would cause a fuse to keep blowing?
Overloaded Circuit
The most common cause of a blown fuse is when something draws too much power from the circuit. This is most often caused by either too many lights or from using too many plug-in appliances at once. The biggest culprit for this kind of issue is a multiple outlet adapter plugged into a socket.

Most fuses only cost $10 to $20, but you’ll have to pay additional labor fees to have your fuse replaced by a professional. Depending on the shop you go to, labor can cost between $65 and $100 per hour, so call ahead to get a repair estimate.
