Before beginning, disconnect the negative (-) terminal of the battery prior to
working on the positive (+) terminal to prevent a short to ground. This is important,
unless you want to spend the rest of your life with a nickname like 

"Sparky,"

or

"Smokey."

Reconnect the negative terminal only after all connections have been

made.

Warning! A Main Fuse must be installed within 18" of battery!
