This is not the correct subforum for this post. Maybe the mods will move it.
Assuming that your cables are not faulty:
Check the battery voltage. Be certain that voltage reads at least 12.4 volts. If not, your battery needs a charge or replacement.
Turn the ignition key to the run position. Check that accessories and turn signals work. If not, you may have blown a mega-fuse or fusible link. Look for either right at or near the connection to the battery B+ terminal. You may also have a faulty ground or ignition switch.
Turn off the ignition and turn on the headlights. The battery voltage should drop by about 0.1 volts. If not, your battery has likely lost capacity and may need to be replaced.
Turn on the headlights and crank the engine. The headlights should dim but not go dark. If not, your battery has likely lost capacity and may need to be replaced.
