Prius, 08, smart key.
Dead on Sunday am — nothing works. Not even with key in slot. Put trickle charge on the underhood postive and neg to body bolt. Got enough juice to open rear hatch (and dome light comes on )
Replaced with toyota battery. Neg cable taken off first, then pushed up out of the way behind carpet.
Still dead. Still nothing. Checked both batteries at Autozone. 94 and 100% — wasn’t battery in the first place. Checked clear window fusible link on top of pos post — still good. Can get locks and lights to work with trickle charge, but NOTHING if disconnected.
