Electrical Problem!!!

I have a 1990 jeep cherokee xj with an aftermarket radio.
First, the radio started to shut off when I applied the brakes...
Then the dash lights stopped working, and now when i press on the brakes my running lights turn on, and when i pull the knob to turn on my running lights and dash lights, my radio shuts off completely


Its all screwed up and I just want it to work...Any info on this would be greatly appreciated


thanks guys

Take a look at your battery terminals. Are they corroded? Especially the negative one?

Was the dash dimmer wired into the radio? A lot of new aftermarket radios have a built in dimmer function that is digitally controlled. The one in the Xj is an analog(mechanical) variable resistor. The difference in voltages needed to run these are too great for the aftermarket deck to handle so after a period of time, depending on the quality of the deck, the unit will fail. I'm guessing this is why it's affecting your lighting, no guarantees though.

x2 on checking your grounds, battery and alternator terminals also. Never hurts to do regular maintenance on these as Jeeps enjoy clean wiring and dirty paint, not the other way around.
