Here's a quick update. The car wouldn't start again today. The battery is clearly low. Either something is draining it, or the battery is bad. Is there an easy way to determine how much current is being drawn from the battery? And does anyone know what is "normal" when the car is off?
I'll get a jump tonight and bring it in tomorrow. Thanks for the helpful suggestions; please feel free to post or send me more ideas!
Thanks,
-Ben
