Well guys, despite the interesting conversation my last post created, I got my 400 running today.
What I has to do was get rid of my 6v coil and resistor and swap it for a 12 volt coil with an internal resistor. The tractor popped right off. I never had to swap the battery or charge it. What I believed happened was my resistor got wet because of the way I placed it next to my coil. So this was a learning experience for me.
I appreciated all the positive posts about my dilemma. It is great to see all the restored FFA tractors and machinery. Of course every one of them has help along the way. Some may have more than others, but it's like that with everything, no matter how old you are.
I'm headed to Iowa State next week to study Ag Engineering, so I will be posting more answers than questions for sure.
