Answer
Hi Ronnie,

       As you know it all starts with the battery. Doublecheck the battery cables especially the positive one because they like to corrode at the battery. Take both cables off starting with the negative and clean or replace as necessary. If you do find blue corrosion at the positive battery cable terminal or it doesn't want to unscrew that means the case has cracked and you will need a new battery as well as cable ends or new cables.

       After the cables are reattached to the battery recheck to see if there is power. If you have a voltmeter it should read at least 12.0-12.6 volts with the key on or off. If it is more than 4 years old replace it.

       If you still have no power then check the other ends of the battery cables where they attach. Hopefully by this point you have found the problem. If not let me know what its doing and what you have replaced and we'll go from there. Otherwise take it to your mechanic for a diagnostic. Bill
