Resistors, should be tested with one leg removed from the circuit. There are
lots of paths for resistance within the circuit your trying to fix.I am
guessing that you didn't remove the resistor when you measured it. I might
further guess that you have something in that circuit that is bad, thus the
"off" reading of that resistor, in comparison with the rest of the resistors
that were also tested in circuit... just a guess on my part, but I would put
money on that resistor, when removed from the circuit, being within 10 to 20
percent of the correct value....

I have a driver board resistor R64 that is measuring different than
all of the similar resistors of that type that should have the same
value.  It measures 2.21K ohms and the others range somewhere in the
1.8K range.  The schematic calls for a 2.7K ohm.

This resistor is the only anomaly in this bad solenoid circuit, but
I'm not sure what to replace it with, 2.7K, 1.8K?  Not sure why all of
the similar resistors would be measuring so low compared to the
schematic value - those other circuits work fine.  Any ideas?

Your right, I tested them on the board without a leg removed. Should
I replace it with a 2.7K ohm like the schematic calls for?
