Hello,
I am new to this site and a new Mini owner. I bought a used 2002 a week ago and have put 500 miles on it in the past week with no issues. I just went out and turned the key and it would not start. The normal lites illuminated briefly then dimmed and went out. The motor did not even attempt to turn over, no start noises or anything. It is dead in the water! Any ideas? The car has 87,000 miles and the seller told me the battery is new. I will take it out and have it tested tomorrow first thing!

 

Well, I'd have a look at the battery connections... but it sounds like you plan on doing that.
