My Tundra ran fine yesterday. Last night I went to get something out of the truck and before I got to it I noticed the running board lights were flashing. Once I got closer I heard a clicking- about one click a second. I opened the hood and could feel a few of the relays clicking. The click and lights were in sync/rhythm with each other. The battery was dead and it only took about an hour or two to drain it. I disconnected the battery to stop the pain...

I was going to charge the battery and hook an OBD II sensor to it to see if anything popped up.

Other than that, does anyone have any thoughts?
