- 2004 New Holland TC40DA w/hydrostatic transmission & 4wd; 1983, MF 230
Update: I got the tractor to crank/run! On the third time through all the safety switches I discovered that the Range Selector safety switch (located on the side of the transmission) has gone out. When I had checked it before, I had discovered that the wires had pulled loose due to some limbs/shrubs, whatever, and I very mistakenly assumed that the switch itself would still be good. This time around, I simply disconnected the wires and jumpered them together; and wouldn’t you know … The darn thing started up.
But, as luck would have it, I still have the same issues with the LaneShark/grapple system, high/low range, and the instrument panel not working properly.
With the tractor issues, of not starting at all, I felt all along that it would’ve had to have been in some of those safety switches. Turns out I was right there. With these other issues, I’m tending to believe that something is shorting out in the electrical circuits for the instrument panel/tachometer, and Electrical side of the “electric over hydraulic” system which controls the high/low range and the third function valve for the root grapple/LaneShark. I have tried to follow every wire lead that I can find In search of a short to ground or something. I am either overlooking it or somehow looking in the wrong place. I feel sure that once it is found, it’s going to be something that really wasn’t that big of a deal if I had only known where to look.
I continue the search.
