Without going into my old books I don't have a schematic on hand to post/show you. You have to remember the Armature has HUGE Gauge wire compared to the field wires Does it charge/operate correctly? if so, let it be and just "believe" Ha.LOL! |

If the armature was, in fact, shorted, you'd see smoke, the S/G would get hot, and it wouldn't spin the engine over.

"Before you said 1 ohm of resistance, and now you're saying zero...which is it? 1 ohm is probably about right. "
Measuring very low resistances with a 2 wire measurement (like a VOM does) is pretty pointless... and generally not repeatable even with a good meter (I use a Fluke 87). What do you measure at the battery terminals when the motor is running? Are you sure you're not on the AC range when you're seeing the high voltage reading? There's no way I can see of getting high voltage out of a S/G operating at normal RPM range. I'm thinking measurement error , not equipment (S/G) error. John

Ok I checked things over and ordered a new voltage regulator and things are much better. I also found out that DVM that I always use, would spaz out when it got close to the tractor when it was running. Switched to my back up meter from radio shack, and had no problem reading the voltages. Sorry I took so long to reply but I have been busy cutting up and splitting my truck load of (9 cords) wood. Just have a little left to split. Thanks guys for all of your help!!!

Good to hear it came out well.
I've seen the "dancing readings" with a cheap Harbor Freight toolbox DMM too. I should drag my O'scope down to the garage and see what the charge line looks like some day.

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.
