Keep this in mind when checking resistors. There is nothing that will make a resistor read high, other than a bad resistor. Any other parts of the circuit, ie: parallel paths, will cause a lower reading. I always check in circuit and if it is low then I remove it to check it. If it reads high, I just replace it. Since most resistors drift up in value, there is usually no need to take a resistor out of circuit for an initial test.
