The 20 amp fuse (located in engine bay) labeled "back up" blows anytime I put one in. And today I took out my stereo and put a new fuse in. And it didn't blow until I plugged the stereo in. Will a new stereo fix this? Or what is my problem?

Hi,

When the radio was unplugged, did everything else work and it just blows the fuse when you reconnected the radio?

If that is the case, was there a problem with the radio prior? Did you check the wiring at the radio to make sure nothing is shorting or the plug isn't bad?

I looked through the wiring schematics. They indicate fuse 8 in the under hood fuse box (20 amp) powers the radio and the lighting you mentioned. So, if everything works until you connect the radio, either you have a wiring issue right at the radio (bad plug, damaged wire) or the radio itself is bad.

Let me know.

Joe

Hey Joe. Yes, everything is working now. Radio is still out. The wires are fine. Could not see any damage to the wiring. Car sat for the summer. When parked. The radio worked.

Hi,

It sounds like something shorted in the radio itself. Ugh! You have the same kind of luck I have. I've seen the pins get corroded, bend, and then short at the connector, but if they all look good, the problem is the radio.

I don't know if you need them, but here are the directions for the removal and replacement of the radio. The attached pics correlate with the directions.
