Hi Daren, As long as you wire it to avoid the problem John mentions, you do not need any resistor or light or diode. The #1 spade terminal needs to have 12v+ when the tractor is running and isolated from everything when it is not. On my diesel tractor I do this with a NO oil pressure switch that actuates at 5 psig in the line between battery + and the #1 terminal. On my gas tractor (magneto ignition) I use a DPDT 2 pos toggle switch to 1) ground the mag in the off position and also isolate that lead to the alternator and 2) take the mag off ground and also supply 12v+ to that #1 terminal in the on position. Works great. I take it you have a conventional battery ignition system so I don't know if your ignition switch is capable of being wired to avoid the problem John mentions. While a diode would prevent any feedback from the alternator via that lead, I don't really see how a resistor or a light would. The idiot lights in automobiles usually have 12v+ on both sides of their contacts - hence no light during normal operation. When the alternator fails, that #1 terminal goes to ground in the alternator and the light lights up. You are correct in just jumping the #2 spade terminal directly to the alternator main output stud.  Rod

Box Plow Blues - by Tom Schwarz. One of the first implements most tractor owners obtain is the box plow. For very little money, this piece of equipment promises to plow and flatten any hill or vale on your ranch road or farm. At least that's what I thought! As simple as a box plow appears, it can be rather challenging to make work correctly. In our sandy soils of Florida, traction is king. You can never have wide enough tires or heavy enough weights to get all the traction you want � unless you own a monster tractor. U
