2011 T&C starts sometimes but rarely. Have to try 20 or 30 times. Any ideas ?

 

I've had trouble with positive battery post to wire. There's a brass (?) plate at the wire end that connects to the post clamp thing. It looks like metal to metal but I have to rough up the surfaces now and then to make the connection good. But 20-30 times probably means you have an ok connection and it's just not turning over. An ignition fuse maybe?
