Hi, I have a 2004 CH 613 MAC tractor that seems to lose power at the drive-in a few minutes. Lightning bolt is on and the flash code is 79. I also have a code 11 which I believe is no oil pressure which I know I have a bad sending unit which I am awaiting it to arrive. I can’t seem to find anything on the 79 code and greatly appreciate any wisdom in this area. Thank you.
