Very unusual problem, no power in the car
I have an unusual issue, in my 1999 TL the battery died so I
tried to jump it using an Enclave but the car won't jump and the
voltage output from the Enclave drops to zero when connected to the TL.
I even tried connecting to the TL without the battery in the TL and still the Enclave drops to zero. I removed a fuse panel cover by the firewall on the passenger side and located what I believe is the master fuse.
I have continuity across both terminals as well as the smaller fuse of the same type next to it.
What can be the issue here?
