on my truck i was curious if my block heater was still working so i watched those youtube videos to test it and seems like a good method was the multimeter method.
they say to set the multimeter to ohms and then measure the resistance when hooked up to the hot and neutral on the plug.
well i did that a few times and it starts at 0 and then when my multimeter makes contact it jumps to some values and then drops back to 0 after 1 second. i tried changing connection and it does the same thing like it doesnt give a constant ohm reading. it just jumps to a random number and then back to 0.
however i did the ear test and when i plug it in, 2-3 seconds later i can hear a hiss/kettle noise from engine bay.
is there a reason my multimeter test isn't working? if so, what r some other tests i could try
thx!
