Well....I'm BACK!! The Spa has worked PERFECTLY until now. And as expected since it's a 2001 model I was just waiting for something to happen. It stopped heating.
-> While it was still attached, I tested the temp probe which "appears" to be good. Ohms tested between all 3 pins and the only reading was 8.8 ohms between Green and Black which I am reading is correct'ish. Probe terminals where cleaned.
-> New heating element from, in the beginning I broke a terminal off (DUH). Testing the right element post to to GRD trips the GFCI breaker (good), and between the left element post to to GRD reads 120V. Testing between both element posts 0.0 BUT...it "should" have been in heating mode but, I can't remember it was or not.
-> No noticeable issues (burnt, broken, damaged) items.
-> Fuses are all good.
-> Shutdown, rebooted, kicked, cussed and still NOTTA.
So...I guess if I wanted to remove all all the "common" culprits and test them, I could BUT...thought I'd send an Hail Marry to see if one of you smart peeps had any good ideas or some free money, say appx $500-600 as a early Christmas present?
And I guess my screen name is ironically PERFECT for this post. @#$@!!!
