Customer Question
I have a kenwood...

I have a kenwood excelon radio that's about 4 years old and out of the clear blue it is flashing the word protect. I have shut it off and waited and turned it back on and the same is happening. HELP!!

Mechanic's Assistant: What's the make/model of your device? How old is it?

Ok I just know it's a Kenwood Excelon I have to go out to the car to see if i can find numbers.

Mechanic's Assistant: How long has this been going on? What troubleshooting have you tried?

Yesterday morning when I got into the car to go to work. It worked fine Sunday. I took the cover up and put it back on and just turned it on and off. I don't know what else to do.

Kenwood radios have a protection mode to help protect them against overloading. Your radio will go into "Protect" mode if it has an internal short, a speaker is bad or the speaker wiring has a problem. Many of the problems that trigger protection mode can be resolved by following these steps:

Step 1:

Reset the receiver by removing the face plate and pressing the "Reset" button with a paperclip. If this solution doesn't fix the problem, continue with troubleshooting and reset the receiver after each step.

Step 2:

Turn off the receiver and disconnect all speaker wires.

Step 3:

Turn on the receiver. If it quickly shuts off, the receiver has an internal short, according to Kenwood. Contact Kenwood customer service to have the unit repaired.

Step 4:

Connect one speaker at a time. If the receiver shuts off after connecting a speaker, that speaker's wiring or the speaker itself has a problem.

Step 5:

Replace any faulty wiring.

Step 6:

Replace a speaker if you have replaced its wiring and your receiver is still going into protection mode.
