After charging my battery backwards today for about 5 seconds like a dumbass,
my 430n has no power. The fuse is good in the box by the battery, is there another fuse or a reset? I'm not for sure that the reverse charge did it because the battery has been dead for over a week, I replaced it today, and thats when I noticed the radio has no power. Any suggestions?
My Jeep is a 2011

I am betting your battery is toast. And is cause for the 430N problems. Bob K.
I replaced the battery, that's when I noticed the problem so I'm not sure if the reverse charge caused it.

If you have the premium system, there are two fuses to check. There's one for amp that could be the cause of the issue.

Thanks guys, I saw the amp fuse in the book but I haven't checked it yet. The dealer tech says the problem should be in that fuse box somewhere.

After thinking about it, I remember checking the radio and amp fuses and a few others but none looked bad. I'm hoping they can be bad but not show it.
I found today on another jeep site a guy with the exact same scenario and it was his amp fuse.

There is a small contact area for both blades on the top of the blade fuses. I have a voltmeter with a small enough tip. I place one end to ground the other to that contact area. I use this method exclusively as I have found blown fuses that looked fine to the naked eye.

Be sure and post what you found that was causing the problem after it is fixed to possibly help someone else someday if they search and find this thread. Fuse #, location, etc.

Yes. And also you can pull the fuse and run a continuity check on it. It is not always apparent to the naked eye.

Yep, that is what I figured. When mine went out, it took an embarrassing trip to the dealer to find out there was a separate amp fuse.
