Glad Dennis and Alistair replied because I never received the original post.
Also, because they have real advice.

I send Greg good wishes for a safe trip home and look forward to an update on the issue.

And, I have no idea what it is but I’m going to say a bad ground as almost 3 out of 4 times it seems like that is the solution.  So I’m sticking to that.

If I go over that, the battery light comes on, and very soon the dashboard lights dim and headlights dim. I let off the gas to get under 3200 rpm and the battery idiot light goes out and everything brightens up again.
