Swap 12v for 120v Fridge Element? UPDATE 2
EDIT--it turned out you can't swap them--they are not the same and it would fry things if you applied 120v to the 12v element ---------------------- UPDATE 25 Jan--12v is cooling down the freezer....

Update 2
Second converter on fridge "terminal block" instead of the regular wires from the house battery bank. This was the easiest connection.
Started with converter set to 15v. 193 watts warmed up. Very slow to get the freezer to cool down any. Checked the voltage at the element pigtails 14.3v. So that is 0.7 drop across the terminal block and PC Board. About 13.5 DC amps draw (using AC watts and DC v)
Cranked the converter to 15.3 (under the 15.4 limit) and pigtails now 14.6, 202 watts warmed up. Freezer coming down in temp much better now. Acts like there is a threshold to get it really going.
Anyway, next thing is to wait for it to bottom out and cycle before declaring victory. Not there yet.
If this works I then need to find a place to mount the second converter (under the fridge has a place) and pass wires up through I hole I need to drill. Should be ok.
