00 Hyundai Sonata, Battery Installed Backwards
installed the battery backwards in my Ď00 Hyundai Sonata.
I changed the fuse right next to the battery. The car runs
fine now, but the radio, power locks, clock do not work.
I have checked the fuses under the dash so far so good.

You need to get back under the hood for an answer. On the driverís side inner fender, just in front of the strut tower youíll see a black plastic box called the Engine Compartment Junction Block. Once you remove the cover, youíll find all kinds of relays and fuses. Inside the junction block, you should see a couple of 30 amp fuses labeled passenger compartment junction block. Itís likely that one of those fuses has failed as well. Hyundai, like many manufacturers will use a fused power distribution block with large fuses to supply electrical power to the smaller circuit fuses found in the passenger compartment fuse block.
