Thanks Marzach, I’ll test it and reinstall if good. My quest for 12 volt conversion may be easier than I thought due to the P.O. already putting in most of the 12 volt stuff. How do I know if the sending unit is 12 volt ( the last of the 12 volt conversions or is there any more that needs to be done?). Thanks to the rest of you guys too. What an invaluable resource Stovebolt nation is!
