I've chatted with some electricians and electrical inspectors about this. They don't like Al wiring, but they also believe it can be safe. The problem is that the connections get loose over time. Tighten those connections, and the system should work fine. Every connection should be accessible.

Yes, it's not great, and can get brittle, but as long as you tighten the connection periodically it seems to work OK (40 years and counting).

The weird thing is that I've taken every connection apart that I can find in this circuit and it's still not working. I can only assume that I'm missing one. I've been working on it in the evenings when I get home. I think I'll just have to wait until the weekend when I have more time.
