Default Cuc Cadet HDS2165 - Voltage Sensor?

In the cub cadet 2165 electrical, there is a voltage "sensor" - part number 925-3251. I have looked around to try to find out what it does exactly in the schematics, but its actual function is a little elusive, theres no description of the part anywhere i can find. Does anyone know what it does exactly and how it works in the schematic? Im really try to sort out if it behaves as expected.

I can't answer your question but doesen't it seem strange to have fuses on both the positive and negative sides of the circuit.
Another question would be, what the hell is that thing with the green, brown, and white wires going into it??

Way back in the 1990s when I was selling Simplicity, my friend sold and repaired Cub Cadets....(he still owns that shop). Both Cub Cadet and Simplicity used v twin Vanguard and Kohler Command engines. For some reason the PTO clutches on the Cubs started failing at an alarming rate. The Simplicity units faired much better. IIRC, it caused damage to the bearing surfaces on the crankshaft. This sensor may have been designed to mitigate any stray current that may have caused that situation.

Looks to me like the voltage sensor is to sense if the tractor is charging the battery or not. If not, the light comes on.

Every other component is designated, I guess relays are top secret.
That's why I never pop open the hood on my vehicles, too much stuff to comprehend in there.

If you "secrete" you probably already know where to look.
Anyways, you gave it away so you lost your clearance to classified info.

Oooooouuu Darn spell check. Greg increased the file size so I will try again, I will do it now momentarily.
I will try uploading the 2165 PDF so you can see it more clearly. I also uploaded the 1282 diagrams.

thanks for all the help. It does seem to be charging. The alternator itself puts out 22 VAC. The regulator puts out zero VDC until you tie it into the system. Regulator is brand new. The amp light does come on slightly as you start increasing electrical load with pto, lights. I tied an ammeter into the output of the regulator to test it. Its annoying that there's no real description the voltage sensor operation anywhere.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
