Tractor wiring finale

To finish up my Cub Cadet wiring adventure, it turns out that when the previous owner ran a line to the batt terminal of the regulator all he actually had to do was to move the grey wire from the hot side of the starter to one side of the ammeter. I actually spliced the grey wire to a little of the previous owner's very long wire since the grey wire had quite a large ring terminal on it. Viola it works, that easy. One downside is that it doesn't measure when cranking since that comes off the switched side of the starter switch but everything else is measured including the

With the ammeter sorted I took a look at the bracket which at one point must have been chromed but is now just rust. I let it soak for a few hours in a bath of evapo-rust, then cleaned it, dried it and hit it with some primer and yellow paint.

I let it dry overnight and then sprayed the backside. When that was mostly dry I baked it in my toaster oven but had the heat too high and bubbled the paint. That subsided into an interesting crackle look which goes with the mostly rotten paint on the rest of the tractor.

Here with the engine off, headlights on we've got discharge.

With the engine running it charges:

When I turn on the headlights the charge rate dips for a second before it goes back to the same spot. I was pleased to see that the starter/generator charges even at very low engine speed. My other Cub Cadet seems to want more engine speed before it charges, I guess I should order a starter/generator rebuild kit for that one as well.

After all that fun I took a few minutes to add slime to the left front tire which was low and put some grease in all the zerks.

Most importantly I was able to start the tractor cold without starting fluid for the first time in about a year. I was so happy with it I went out and bought a padded seat cover. The machine had one when I first bought it but it got torn off last spring so I'd spent a year sitting with a dirty old towel on the metal seat. I'm ready to plow snow in luxury.
