Jeep wouldn't start this morning. Turned the key - only got a click and the lights went out. Lights came back on after a second, but still no start... only the click.

I did the usual things. Jumped it, tapped the starter, etc., but still nothing.

Popped the clutch and drove to work. On the way to work, I noticed that when I put the turn signal on, the radio would cut out until the signal turned off.

Any ideas? I parked on a hill today so it'll be easier to start after work.

Should I drive it to a repair shop, or is this something I can tackle?
