I have power to the engine compartment fuse/relay box. I tested all the fuses and relays. I have not tested the harness coming out. I would think something would turn on anyways.


Thing is, there is no power going to anything. I have tested the battery. I gave the car an external power supply. Nothing. Literally no power to anything.


Yesterday, the stereo turned off and back on while I was driving. Then the car would not start and no power to anything. I let it set for about 30min and everything was fine.


This morning, nothing worked. I messed around with the batter and the power going to that fuse box and the electrical turned on but all shut down again when I tried starting it. After a few times of that, nothing works anymore.


Any ideas? Thanks.
 
Check those battery connections for tightness & corrosion! How old is the battery? Has it been load tested?
