Rmmagow,

As far as I know there is no thermostst on the block heater. Plug it in and see if you notice a spark when you make the connection. Try a couple of times since you are using AC current.

If you get a spark, it will work. If not, probably won't work. You then might check with an ommeter. Should be in neighborhood of 25 ohms if its OK. Should pull about 5 Amps or more.

These values are just an educated guess but should tell if the heater will or will not work.
