Engine Electrical Question
Howdy, I'm a new member. I have a Cub Cadet Garden Tractor (model 1440, B&S Engine). Amp indicator light stays lit. Output from the Voltage Regulator (VR) is less than 1 volt with wide open throttle. Before I buy a new VR, how can I be sure the alternator/stator isn't the problem? I measured the resistance between the two AC leads to the stator, and I got 2-3 ohms. Is that too high? Is a resistance measurement of this value the "typical thing you see when a stator fails"? Is there some other technique for evaluating the stator? Thanks!

Engine Electrical Question
Thanks, Roland. Is it correct to say that, at WOT, I should see +28v between the two leads coming from the stator? Or should I see +28v from each stator lead with respect to ground? -- Dave

I can't say for sure on a B & S engine, but it is measured as indicated in the linked diagram.
Basically, there is about 30VAC coming from the stator and the V/R rectifies the voltage to DC and regulates it to around 13.7VDC.

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.
