Just after sunrise this morning, Lisa and I went down to the Astro to assess the situation. Remember that last night, Lisa's improvised test kit showed that there was full power in the battery itself, but none of it was making to even the least of the minivan's systems.
We both investigated the various leads that run from the battery, wiggling them a bit to see if anything was loose. I did find a loose vacuum connection near the battery, but that had no immediate bearing on the issue. But after wiggling wires, I went in and tried one of the small lights in the cab. It worked! But the car would still not start, so we were not out of the woods.
( Terminal Problems )
Lisa disconnected the battery so that she could test the terminal block connection. This was much more difficult than it should have been, because while we have lots of tools on board, none of them were the right size socket or box wrench for the battery terminal posts. Lisa hates having to use an adjustable crescent wrench on these.
Suspiciously, there was a fair bit of corrosion built up on the positive battery terminal. Lisa cleaned the white powder off as best she could. She then pulled the power lead off of the terminal block, inspected it, and put the battery back in. We then tested the connection on that power lead and it worked! She reconnected the lead to the terminal block, and we checked one of the interior lights. It worked. Now the acid test. She turned the key and Astro started immediately!
( Lisa Gives Blood )
Lisa's theory is that the corrosion on the positive battery terminal was preventing a good connection between the battery and the terminal block. This was why we could get a good test when connecting a test line to the positive battery post, but not to the terminal block. Cleaning the side post and the battery cable allowed the connection to work again.
Lisa put away the tools, we went back to the room and cleaned up, and Lisa cooked us scrambled eggs and bagels. Might as well use the full kitchen that we had today only!
So what was looking like what might require us to rent a car (~$2000) to finish the trip while we left the minivan with a Chevrolet dealership for the remainder of the trip appears to come down to us buying around $50 worth of parts and tools for safety's sake.
After we finish breakfast, we're checking out, going to buy tools and parts, and restart our trip, only a few hours behind. Fingers crossed that we have time to see a few things in Yellowstone National Park today.
