When I try to measure the BB motor resistance with a DVM the meter
jumps all over the place, in the neighborhood of 1 k ohms. The mean
value of the jumps depends on where the wheel is positioned. The
"eyeballed" mean values varied from 0.3 k to 1.8 K. depending on
where the wheel was, even though it was moved in small amounts.
There are 5 different conductors involved: graphite, brass, copper,
aluminum, and at least one type of steel, possibly two. This may be a
complex thing.
We had a fair sized (Mag. 5) quake here when I was typing the prior
post. No matter. Typo rate is probably the same - bad.
