How do I test a block heater in this tractor. Aside from trying to feel if the block is warm. I am assuming that I can test the resistance across the plug with an Ohm meter. I am not having any luck finding out what the reading should be if it is operating correctly. I had to start the tractor yesterday to blow some snow. After being plugged in all night, the tractor did not pop off as it has in the past, and actually knocked for about a minute before running smooth. Any help will be appreciated.
