Engine block heater

I have a couple of questions about the engine block heater. Does the engine block heater have a fuse? If not, how can you check to be sure the block heater is working? I have a multimeter but not sure how to check the switch to see if current is going to the engine. Any help would be appreciated,

How about one of the digital non-contact thermometers?
Check the temp before you turn it on, and several minutes after.
If the block heater is working the block should be getting noticeably warmer.

Way back when I lived in Iowa and used such things it was obvious if the heater was/wasn't working just by laying a hand on the engine (when the outside temp is way below zero, anything above freezing feels pretty warm by comparison).

Resistance in Engine block heater

Take your Ohm (multi-meter) meter (make sure it is on an a fairly low setting) and measure across the two prongs (not the ground prong) on the plug, you should have some where around 10 to 25 Oms of resistance (depending on the wattage of the block heater, if the ohm reading is high or open you have a bad block heater or plug. To test just the plug disconnect the cord from the block heater (most of them just screw no to the heater at the block), and test the block heater right at the engine doing the same test as you did thru the cord, to test the cord, unplug it from the block heater and one side of the cord at a time, one probe will connect to the male side, the other probe will connect to the side that plugs into the block heater, you should get similar readings just thru the cord, very low ohm's.
