Dead battery. good Samaritan with cables inadvertently cooked my car (i think). car starts and runs fine. headlights work. No radio, dash lights, shift lock, tail lights, or power windows. all these are associated with this box. seems like fuses in primary box are fine. looked at underdash panel could not find any blown fuses. is there an inline fuse or somewhere a guy could start looking for issues? please help a poor non-electrically inclined kid.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

You have to start at the battery. Is it fully charged? It should show at least 12.6 volts to verify a good battery. If it is less than 12 volts, it will not start the engine anyway, so it must be tested and recharged if good, or replaced if bad. Next the positive and negative cables at both ends of them must be clean and tight. By now you should be able to have headlights and other accessories. And the key turned to on should light up all the warning lights and gauges on the dash, and when turned to "start", the engine should be cranking over and then run.
If the car is completely dead, start at the battery. If you still suspect fuses, next check all the maxi fuses- the power distributors right after the battery. Only one of them would cause whole differing circuits to not have power.
Blew a fuse is likely problem, especially if you did not jump it correctly. Cannot tell you how many times I have walked up to people in parking lots to potentially save their life and/or limbs. Connecting a dead battery to a live battery wire to wire is just plain dangerous. Start at the dead battery. Connect the red cable to the red (+) terminal on the dead battery. Connect the other end of that cable to the red (+) terminal of the live battery. Connect the black cable to the black (-) terminal of the live battery. (CAUTION: Before making this connection, make sure the other end is not touching a ground). Finally, connect the last connection to the dead battery's car on a good unpainted grounding point away from the battery if at all possible. A usually good point to use is the area where the hood latch is located. Small sparks will let you know it is a good ground. Start the live battery's car. Let it run for about 5-10 minutes with all lights and accessories turned off in both cars. Now attempt to start the dead battery car. Disconnect in reverse order. Good luck and be safe.
try to disconnect the battery for about 20 minutes. hook it back up and make sure you have the positive and negative wires on the right terminal. wrong way can short and burn your entire electrical harness. Check the fuses.
not taped in harness it is bolted into fuseblock on outside of fuse block are 4 little locks holding in part of fuse block using small screwdriver release locks by prying outwards while pulling up on 100 amp fuse when it has released enough it will expsoe the bolts holding in the 100 amp fuse one side is an 10mm the other is a 8mm MAKE SURE YOU DISSCONECT THE BATTERY 1ST
Check your connections for tightness and corrosion. A corroded battery cable/post will diminish the current going to the dead battery.
Check jumper connections
Dead battery; the worse off the battery is, the more time it will take to charge the battery sufficiently enough to start the car; a completely dead battery with bad cells will never recharge sufficiently enough to hold a charge and start the car on a regular basis
Hope this answers your question. Best of luck. Greg
