No, definately not normal, unless...you reversed the polarity. Happened to me once.

An arc when connecting the second bat terminal [-] is normal, but doesn't always happen.<br /><br />See similar thread with more info here:<br /> http://www.iboats.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topic;f=27;t=002154

If you have a clock, radio with memory, automatic bilge pump, any of those may draw power when you made the connection.

Re: arcing battery post

They don't draw much power but you would notice a little arc. If the arc is more substantial, listen for the bilge pump. If its running, the float switch may be stuck.
