When i made that first post I only had some stupid wiring diagram that used pictures to display where the wires ran, but it just show 5 wires going to a controller. Then I spoke to my professor about it and he showed me the alltrax diagrams, then I found the rest of them. I made that first post after 9 hours of being at my garage trying to fix this thing because it was suppose to be due this past Monday, but I told my professor I ran into some problems and he was OK with it. I do have anther question on top of the diodes, which I will get to you tomorrow, sorry if i made anyone mad, including you frodus. I usually do all of the research first rather then think I know what I am doing, because I always tell my friends that I am the real world Tony Stark (if anyone knows who he is). After I did my research I found a lot of information so I kind of helped myself, but forgot to erase the post where I my mind was shot after drilling, grinding, and welding all day at the garage and being in a panic over two diodes. I was wondering how you run the key switch with the alltrax controller because the diagram shows a foot throttle, which obviously I dont have, and it shows a wire splitting off and going to the contactor as well as pin 1 on the controller. If it runs to the contactor isn't that going to be noisy? And it shows the wire to the key switch as coming off of the fuse for the 72v, isn't that going to run 72v through the key switch?
