I checked the breakers in the main box and there is one there labeled "Eng." and it was on, so I have been running that block heater every time I've been plugged into shore power. We have been in the valley for three months. I know I'm going to label the plug in and the power cord that goes to the block heater. Wish someone had done that before. I thought there should be a wire in engine compartment like my Dodge diesel pickup had and looked for one, but no luck. Love this forum.
