You're right; I had that backwards.

Yes, odd, but then I don't claim to understand this fully. I THOUGHT 
I had an answer, but now that the resistances are the other way 
around, I'm lost again.

Sometimes it just takes the step function of applying the voltage to 
get the late style clocks working. I also find that taking the late 
clocks out of the dash, while keeping the power applied, and then 
twisting them quickly back and forth about a vertical axis, will 
often start them. I'm surprised that normal road vibration doesn't 
seem to do the job, but that vibration doesn't contain much motion 
about the vertical axis.
