No power on left side of both fuse boxes

just decided to join, already got a lot of advice.
now I have a problem, adding off road lights,
massive short in power to lights checked all the fuses twice found out no power on left side of both fuse boxes.CAN ANYBODY HELP??????

 

There is normally a large main fuse (100 amp or so) at the main fuse box’s connection to the battery. Did that fuse blow?

 

Time to break out the Meter get some real numbers.

Most time what you have done caused the short

Some circuits are switched Power as well

As stated check the main fuse and go from there

 

we checked all fuses,and sockets, ohm's and amps, from battery on in, looked for any fusible links, hate to say it gonna have to take to a professional, this my primary vehicle, can't be down to long
