The tachometer in the tractor apparently uses an aluminum can over a magnetic rotor. To free the tachometer rotor shaft we used WD-40. In the process of cleaning the shaft the fluid apparently got in that assembly causing increased drag between the rotor and can causing the tachometer needle to...

The cable was replaced with a new cable. The wire bundles coming out of the panel are hard wired to the panel. I don't know where the connectors are located for the cables. Are they in the same basis area? One would think so; but I would like to know before I order a new panel.

This morning (0F this morning) the idle speed was indicated as 2500rpm versus 400 or so that it should be. It was somewhat lower the other day when it was warmer. So, I suspect it's related to the WD-40 I used to free up the tach shaft. The bottom line is that I will probably have to replace the...
