Agreed, that is the crux of the entire thread. The Double sided sensor
is working and for some reason the single sided sensor isn't generating
the index pulses.
The original question was put out here to see if someone knew of a
jumper that I missed in the service manual.
The comment you were replying to was me responding to someone else. They
said they had seen double sided drives that did not have the extra
sensor and I said I had never seen that.

A double sided drive that can read single sided diskettes has to have
two index sensors as the index hole is in different locations on a
single sided diskette than on a double sided diskette.
