Hi all, new to this forum and new to snowcats. I came across a good deal on an LMC-3700C, so I bought it. It needs work on several things, but runs great, tracks are in fair condition and hydraulics seem good. It has a plow on the front, but no tiller or attachment on the rear, at this time I don't need that anyway. Mouse nests under the seat, in the air filter, inside the heater box, and a few other places. They also decided to chew on quite a few wires on the instrument panel. I've rewired that and starting to trace wiring in the cab and the rest of the machine. Electrical wiring is an issue but I'm working through it.
I have a manual which helps quite a bit, but I can't find any detailed information on the what is involved in the range selection. If anyone knows how this functions please let me know. I have traced 2 wires from solenoids in the rear (solenoids attached to a hydraulic distribution box) to the D-handle range selector switch. There are several lines attached to the distribution box and 2 of them have solenoids plumbed in them. I traced these wires to a momentary on/off push button on the D-handle, and switch on the instrument panel labeled "3 speed lock". Do these solenoids have anything to do with the mid-high range? Do you select mid or high range with the mid/high range switch and then engage the "lock" switch to keep it in that range? I can't find any reference of how "high speed" or "three speed" lock works, or what it does. I'm including pictures of the distribution box, the picture of my 2 fingers are the solenoids that are controlled by the D-handle range selector switch. The 2 pictures with just 1 finger are the other 2 solenoids plumbed in line controlled by the push button on/off on the D-handle, and the 3 speed lock on the dash. The other pictures are just to help someone identify what part I'm looking at.
One more thing on the solenoids, I get continuity with a multimeter and when I connected power to them I got a spark, but no click you normally hear when a solenoid is activated. This is without it running. I don't know if it needs flow through the box to function or maybe the fluid is thick because of the temp (20's F).
I can't start it right now. I removed a hydraulic line that was bad - so I have to make a new one, a bad hydraulic cylinder I'm waiting for the seals to fix, still working on the instrument panel and tracing wires, and I have it under a lean-to with it the sides tarped to keep the snow out. So I'll have to wait to do a running test.
I would be grateful for any info on this!!
