Jerry,
I now have a flawless Suburban. But I can maybe help. We will be back on Tuesday.
I've done the trouble shooting and replacement for both the element and limit thermostat. Roger Burke taught me where to poke the voltmeter probes to do the testing. I have the tool for the element replacement and don't need it anymore. I will "gift" it to you!
Tacos or Pho this time?
Bill
PS: A neighbor here at Pacific Shores suggested I got the Beaver too wet, it shrunk and now looks more like a Squirrel.
