I just recently converted my 1950 Farmall H to 12 volt. I followed the instructions to the letter as per the Fitzgerald/Steiner conversion video and instructions. I also installed an electronic ignition (pertronix), as well as a starter solenoid and push button. My tractor will not turn over after this conversion! The starter winds up and everything sounds like a normal start, but it will not fire for me. What could this possibly be??? I've checked and re-checked all my connections 3-4 times and nothing is loose or disconnected. I'm getting pretty nervous/stressed out because I am trying to get it ready for my girlfriends son, he has a 9th birthday party coming up on the 26th and he was supposed to be surprised with the tractor....PLEASE HELP!
