Can't believe i did this but i did, i put my new battery in backwards on my 1990 LS400. bought a battery whose terminals were opposite of my last battery. Wasn't even paying attention. The car starts great but nothing electrical works. I checked all fuses on the driver side (interior) and they were good. This happened to a buddy of mine with his toyota tundra. He said his tundra had a fuse in the engine compartment that was a fail safe for something like this. Is there any other area i ca
