How do I check to see if my block heaters bad
#3
The easy check that will give you an idea that it is working is to just watch the male plug when you put it into the female receptacle and put it in and out on mine I will see a spark/arc and know it is working. can take a Volt Ohm meter and check for continuity, should not be an open circuit. lastly is to use a clamp on meter to check the amp draw and this is the best most reliable way.
