Last year I took an advanced electrical course and learned that electricity flows on the surface of wire, not through it. In this picture you can see that much of the wire on the right has plenty of life to it, but that it's surface is corroded. Many folks we service with a jumpstart have good batteries, but wires that look like this. No wire should be exposed to salty air if is to last. If you use shrink tube over your battery lugs and other connections, you'll be much less likely to be dialing Safe/Sea this season!
