I suspected my block heater wasn't working - couldn't hear it when I plugged in. I put my meter on the the two prongs (not the ground prong) at the cord end (opposite of heater) and got 8.5K. Hmmm I thought. I expected to see infinity. However, I'll admit that I don't know what it should Ohm at. Anyone know? Still confused by this reading, and even though there's snow on the ground, I figured I should go under and check the connection at the actual heater. Guess what? The cord was sheared off at right at the plug end (the end that connects to the heater) and just hanging loose!!!! What the heck?!?! This cord is only about 4 years old. I wiggled the plug-end out and looked at it - the orange rubber was disintegrating/crumbling in my fingers! Could the plug end have been sheared by improper engine replacement? Or, could this crumbling be considered normal? Any thoughts on that? OK, to my original question.... I have a permanently installed (in bumper) plug-in for the heater. I'd like to avoid taking that apart - especially if these cords naturally disintegrate and I'll have to replace it again. So, I'm thinking of using some quick-connects somewhere in the middle of the cord in a convenient location. Should I just use bullet-type connectors and shrink? Or, is this there something better? I believe the heater is about 600w - maybe 800w? If so, would 14 gauge connectors be fine (if my googling ability is up to parr, anyways:rolleyes5???
