    Multimeter shows no voltage at "BATT" even with engine running
    With engine running 13.3 volts displays for "ACC" and "IGN" terminals
    The electrical diagram does not show were power for BATT comes from

    Where does power for the BATT terminal come from?

    I see what you mean. The labels on the fusebox don't seem to match anything on the diagram.
    A search shows the + battery connection hitting the bulkhead connector, which plugs into the fusebox. I guess you'd need to pull it and start Ohming out the connections if no one has a better answer.
    It might be productive to post what you're trying to do, or the problem.

    Using "BATT" to power
    -- LED in the trunk
    -- Lights in overhead console between sun visors
    - - Radio memory

    A short pigtail comes off BATT with a ring terminal on the end. The three wire runs also have ring terminals. A #8 machine screw binds them together

    Earlier in the rebuild, BATT was working for it powered the trunk LED. At that time trunk LED was the only circuit connected to BATT

    Looking at my old fuse block the bat terminal is connected to the end of the clock/lighter accessory fuse. Instead of using a ring terminal with a machine screw holding other ring terminals to it, you might want to look for the console lighting connector (orange and black wire) sometimes it has a spare wiring connector coming off it, that could go right to your radio. Or if you don't have a console the empty conector will be right there unused.

    Mulitmeter resistance shows BAT gets power from the clock/lighter fuse. Thanks.
    Now to find what is blowing the clock/lighter fuse which power (on mine); dome light, lighter and console (rear) light

    Where is this "BATT" you are asking about ?

    I'm unsure what model, year and make you are asking about but on a 68 Chevy II Nova and even on my other 73 and 74 Nova's there is a BAT terminal in the fuse block and maybe this is what you are asking about ?.

    On the fuse panel in my 71 in the same location as your photo. Found and corrected what was blowing the fuse "clock/lighter, ctsy" which powers BAT "BAT" has power now
