Headlights get power from the PDC directly. If they don't work at all, then you are losing connection between the battery, and the PDC.

 

it just happend again &wont start...no lights no radio no horn nothing.

 

Check the battery cable from the battery, to the PDC.

 

I did

 

Then you have a problem in the PDC itself...... that should be fun to find......

 

Thanks alot for helping me with this I appreciate it!I think its a short in the pos cable.Gkt it started again.Ill replace it this weeknd.

 

Let us know what you find.

 

Will do.

 

Do a battery test.
Just got a truck that had a bad battery.
The battery would start the truck.
But was it just enough too get it to run.
Soon as I tried to move it the computer hicuped and the motor died.
Lights worked / fans worked (ac).
The computer needs a stable power source.
If the battery is not up too the job the truck will fail,

 

To add to that, I had that exact problem in a caravan I used to own. All terminals fuses & connections looked great, but I came to find out the positive post was broken inside the battery. If I tried to pry up just a little on it, the post would come all the way out, it was detatched from the plate in the battery. A new battery fixed that issue for me. Good luck!
