I purchased a new multimeter, Craftsman 3482170. I applied the leads to the old "thermostat" fuse and the meter read: 20ohms, on the newly orderd part, the meter read: 0.5ohms. I hate to sound like I don't know what I am doing, but in this case, I have absolutely no idea what I am doing. This meter also has a test for continuity, so, on the old part, it read: 0.03, on the new part, the meter read: 0.002.
I assume you would want the fuses open so that they will allow current to run through to the heating element and they close when the current being used or supplied is to high. If that is so, then why would the new part have a lower resistance than the older part that is chared?
Am I doing this wrong?
