You are measuring the coil. You MUST disconnect one end of the diode from the coil to measure it.

For me, you have to disconnect one end so might as well just replace any suspect diodes anyway for one cent each

Yes. The coil resistance is in the order of 5 to 20 ohms and the diode is many times higher than this so you can never test a diode in circuit like this.
