It showed almost nothing at rest, and then jumped to 12.7 when turning the ignition switch to Start.
So this tells me the yellow wire is fine, as is the connection from the battery. Could the new starter I bought be bad?
Thanks for bearing with me.

as I said and now tony has said, you CANT use a MM to do this!!
check the test light (TL) at the battery to get a reference for it brightness.
then check the battery cable at the starter.
then check the yellow wire with someone cranking, it needs to be as bright as it was with the battery test.
you could also check the battery connection with It on start.
I use to do auto electric work for a living and I am and electronics tech for the FAA.
the solenoid requires a lot of current to pull in. any resistance in the path drops the current available to do this.
a MM does not need current to measure 12v. so there may not be enough current to pull in the solenoid but enough for the MM to measure 12v.
if you have an aftermarket car alarm take a look at that wiring. they usually cut the yellow wire and wire in a relay. (NOT the way to do it). the crimps may be bad at the relay if you have an alarm.
