1996 Toyota Rav4 total electrical failure

was the battery tested at all for condition and load test. it stil may be a bad battery or you have a parasitic draw. both of those tests should be done.

Thanks for the reply.

Alternator output test and parasitic drain test performed 3 times on new batteries and 1 new alternator.

I wonder what is next?

was the battery testedfor load test and condition? just because it was replaced a few months ago doesn't mean it's any good.

Thank you for replies.

The battery is 6 days old; the alternator is 12 days old. I don't think they are suspect.
Toyota mechanics have performed load and at-rest tests and parasitic drain test.

RAV4 is at the dealership service dept. over the weekend to see if further drain of the battery happens.

I'm at a loss to imagine what's next.

then the normal suspects that used to be were underhood , trunk and glove box lights, not sure yours has that or not.
