Hi folks...

my car was running well and normally as recently as two days ago, but today when I went to start it...nothing....no radio, no lights, no attenna, and most importantly, no attempt by the engine to start.

The only thing I have done lately is replace the air filter, and I checked all of the battery connections. Just for the heck of it, I got a jump start and it worked fine, but when i tried to restart it, again nothing...

any ideas?
thanks in advance...
