lights flicker and rear abs light comes on

[A_G]

i few weeks back i noticed that when i was coming down the gravel road that when i hit big bumps the radio would shut off and the rear abs would come on for a moment then go away and my radio would come back on.

now its that and the lights...i work night shift..so i need to get this fixed cant be havin this.

I was thinking i have a bad ground...but i dont know why the heck the rear abs light would come on...(it doesnt everytime the radio shuts off but im not always looking for it) but if i didnt have a good ground why would that light come on?

could it be something with the abs sensor...

or the worst. something shorting out cotacting when i hit bumps running all the power into the wire that controls the bulb for the idiot light?

Thoughts?

Have your charging system checked. It could be a flaky alternator. I have a volt meter in my truck and when I am having problems I know the alternator is on it's way out before it goes out altogether. I have also had the batteries so low the radio would go off when I stepped on the brake and the ABS light would come on due to a bad alternator.
