I was blazing a trail on the property last week and some honey suckle got under the machine and ripped the wire off the transmission temp sending unit. No big deal, the sending unit didn't work anyways (lol), but strangely, after the wire was ripped off, the gauge went immediately to full red hot like it does when you ground it out during testing. Before that, the needle on the guage just hung all the way to the low side in the yellow. So today I installed a new sending unit, and after hooking the wire back to it, there is no change and the gauge still acts like it is being grounded. The weird part is, when I take the wire off the sending unit, it still does it.
I thought maybe the brush damaged some other wires under the machine related to the power shuttle, but I couldn't see anything damaged or even anything else that looks like it's part of that sending unit's circuit. It looked like a pretty simple setup, sending unit with wire leading to the gauge in the dash. So I'm stumped on this, I don't even see how there could be any response to the gauge whatsoever when the wire is disconnected.
In the wiring diagram, 'LL' is the sending unit, and the wire (16) runs from sending unit to the harness plug (I bypassed the plug) and to terminal 11 on the plug, which traces to the gauge 'I'.
Anybody have any ideas on what I can look at or what tests I can do to track this down?
