Default 782 Blowing fuses (regulator)

I have a 782 (later over 720,000 model) that is blowing fuses unless I disconnect the wiring harness at the voltage regulator.

Has anyone else experienced this problem?

What should I check 1st?

If I disconnect the harness at the regulator it runs fine, except for not charging the battery. If I plug in the regulator only runs a few seconds and blows the fuse. The blown fuse is then too hot to handle!!!

Thanks,

Daryl

I had the exact same problem and it was a bad Stator. It could also be your voltage regulator.

Here is the thread from last year:

Sounds like it over charging, i would do the necessary tests to check the stator output and if all is well its probably a regulator.

How do I check the stator output & voltage regulator. When I plug them in it dies within seconds.

Welcome to OCC!

Go to our tech section and download the service manual. While your in the tech section, study the section on solid state charging systems. It also tells you how to test.

uplug the 3 wire harness and get it running. trace the middle connection of the Voltage regulator, that will test the B+ DC voltage.

The 2 wires from the stator connect to the 2 outer connections on the voltage regulator.

See this from the tech library:
http://www.onlycubcadets.net/forum/showthread.php?t=32

you need to keep your battery charged since it's not getting charged while running til you fix this.

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.
