Russ, Thanks for the reply! Yes if I don't reread my messages from the phone, auto correct does a great job of turning them into jibberish sometimes!
Fred Street, I've learned, is fluent in jibberish! Lol So I'll let it run for a few more hours tonight. I'd say your assessment is correct about temps. I think the gauge pinning to the high side, along with the heat worried me. The wires seemed fine, only slightly warm. It is ambient cooling with fins on the unit. I wanted to leave the thing plugged in overnight but didn't want to risk it. Is there anything I should check with a meter?
