My 1990 LS 400 battery, an old unit, would barely crank the engine. My neighbor offered his pickup for a jump start. He attached the cables from his pickup to my car while I sat behind the wheel. He cranked his pickup but I didn't seem to be getting any juice...then I saw the smoke from the jumper cables, leaped out and yanked them off.
A new battery and my LS 400 started right up, but the radio won't work nor will the interior trunk release or the electrical door locks. Lights, windows, etc. all else seems fine. I replaced the main Radio fuse (which was burned) and the secondary radio fuse (which wasn't) but the radio, trunk release, etc is still dead.
Any suggesting greatly appreciated.
