first, the backstory.
We bought a 1991 Land Cruiser VX Japanese import from Prince George, 6 hrs away, for $8000. It had a couple minor issues, but nothing that worried me, and it made it home no problem through the mountain pass.
Then, we installed a JVC stereo which fit beautifully with an adapter pigtail. I made the mistake of hitting the antenna switch,
even though the antenna is broken off. Oops. We immediately lost the tach, wipers, windows, and stereo. I shut it off to check fuses (which were all fine), and it wouldn't start again. Just a horrifying *clack clack clack* from the starter.
Turned out all it needed at the moment was a boost. The batteries, however, are not charging. I thought "aha! either a ground short or a bung alternator!" nope. Alternator puts out 14V, but not to the batteries.
Then, I found this:

On page ST-29, it goes over how to determine if the voltage converter relay is functioning.
Pins 1- and 2+ should have no continuity when the vehicle is off.
In my case, they do. I haven't tested the thing with the vehicle on, as it seems the relay is pooched.
The effect is that the RH battery will not increase in voltage when the alternator is running, unless you ground it to the engine block. The relay is blocking the battery from grounding properly.
On the downside, these relays seem to be about $500 US!!! wow!
Does anybody know where they can be gotten for a lot less than that, or if anything with similar specs would substitute?
