Hi all, new to JD tractors and, well, tractors in general. A couple of weeks ago, I plowed my driveway with my JD, which is marked as a model 67, although, from research, it would appear to be a 750. Got about 1/2 way done then had to leave for a few hours.
When I came back, the tractor would not start. The starter motor does not seem to engage at all. In addition, when I inspected the motor, I found a loose wire (has black sheathing but the color of the inner wire is white with what looks like a pink stripe but could be red), which could be the culprit. I will attach a photo of it (sorry, the forum turned the photos upside down) and where I think that it might go, although I do not recognize, nor have I been able to find any sort of identifier as to what it is. It looks like a glow plug to me, but I honestly haven't worked on a non-marine diesel engine that was designed or built after 1980. If it is a glow plug, that's not the issue as I use a block heater.
There is only a clicking sound when I turn the key to the start position. It seems to be coming from the gas tank, so I'm guessing that it is a fuel pump, although my hearing sucks, at best.
Following are the solutions that I have tried:
I have tried jumping it with both a dedicated booster and with my jeep, but it does not seem to improve the situation.
I have tried shorting the starter to get it to turn and it does not.
I have looked at about 50 different wiring diagrams that say that they're for this model, but none of them seem to have a wire that matches the loose one.
Any help that you fine people could give would be much appreciated!
