    I am getting 124 volts at the extension cord. I can try a different cord though to see if it makes any difference. The end is a tight fit. The heater plug may be slightly discolored. I'll sand them tomorrow night. It's supposed to get into the teens.

    Thanks for doing all that work. I really appreciate it Bruce. When I checked my resistance, it measured 19.6 ohms.

    Where can I find a comprehensive service manual for my 2021 ram 3500 and cummins 6.7L HO. I've been having a tough time finding anything. Thanks

    My engine block heater is not working. What is the ohm range for a normal heating element?
