2005 Accord Electrical System Failure
 

I am encountering a problem with the electrical system in my 2005 Accord LX (V-6 engine). There is no power to the ignition switch. None of the interior electrical components work (i.e. alarm, door locks, lights). Yet, the battery is fully charged with 12.5 volts. I should point out the battery is less than two months old.

I tested what I could with a multi-meter. I checked my ground, it is good. I have power going from the battery to the starter, and from the battery to the under the hood fuse box. I inspected all of the fuses in both the under the hood fuse box and the interior fuse box, but all look fine. I pulled the relay affixed to the under the hood fuse box (I think it is a 5-terminal relay), and the contacts look good.

I am at a loss where to look next. Has anyone encountered this problem?

You should test the electrical portion of the ignition switch. Certain wires will read open/closed depending on the position of the ignition switch. I would suggest getting a Haynes manual for your car, or buy the pdf of the shop manual online for your car.

Anything recent done with the car, jump start or anything else. Does anything electrical work (headlights,ect)?

Sure sounds like the main fuse has blown
