No Electrical power Anywhere,,Please help

Im guessing its a Ground issue..But Heres my Question,

I Tried Starting the Truck Today and have NOTHING.....(Yes,yesterday it was fine on my way to the yard...)

Today,I tried to start it and got a quick 'bump' from the starter and thats it..Now I have NO power anywhere,No Interior Lights no Nothing,Batteries are New,Volts were Good Yesterday...

Keep in Mind the Roads are Terrible..Did I Break a Ground? Where do I Start Checking? I bounced the truck up and down while I was Standing on the Step and interior lights came on and off.



Thanks Mick

 

NO...Batteries are between the fuel tank and drive axle , But i'll Re-Check them, They wre TIGHT and Clean

 

Yes..I Have 13 volts at the batteries.....I Tested Them, Everything is tight,Clean and Good At ther batteries..

where do the Cables go once they Leave the Batteries..To the starter? to a ignition Module/ecm? I Crawled underneath to see if i can Find a Broken Cable..But im not sure where to look





Keep in mind folks......I Have NO POWER whatsoever to the Truck.....No interior lights,No CB Radio..NOTHING, Basically In Not getting any Current From the Batteries To the Truck

 

Just came back in.....Cables do go to Starter, Cleaning everything up Now, Will check for Breaks in cables/And tighten all Connections to Starter, I Do Believe that is where my problem is
