My 1715 keeps blowing the yellow 20 amp fuse under the seat next to the battery.
Any idea what could be causing this?
This was happening last fall.
I never figured out the cause and since it was the last cut of the year, I just parked it because I didn't have time to work on it.
I'm not sure what I was doing when it blows (twice happened) but I think it blew when I used the brakes.
The little brake pad it uses is completely shot and need to be replaced.
Is there some sort of switch or something operated by the brake pedal that could blow a fuse?
Any ideas of how to troubleshoot this would be appreciated.
I have no wiring diagram.

The first thing I would look at would be the Seat Switch. It is old (1988-1990), used a lot, and if it shorts to ground, bam.....the fuse pops.

Your owners manual should have the electrical diagram. If you don't have it, you can get it here:

An electrical multimeter is needed to test the circuits to find where your short to ground is coming from. Sometimes it is quite obvious and others, not.

The manual doesn't have a wiring diagram. Any one know where to get one?

Some of the machines I have, the online parts diagrams for them will have a page showing the wiring diagram (but I have no CubCadets, so I don't know if they will have them for your machine).

Your suggestion helped, thank you.
My Cub 1715 is serial number 139-262-100.
I went to a Cub Cadet parts website (Replacement Parts & Service | Cub Cadet US) that shows an exploded view of the electrical parts and their locations however; it's still hard to piece together where the fuse wires in.
I'm sure there is a shop manual somewhere that has an actual schematic.
One odd thing I saw was the seat switch for my 1715 is labeled as a brake switch.
I'll keep searching.
I think the seat switch may be the issue with fuses blowing.
I'm wondering if i can disconnect the seat switch and wire the two leads together to bypass the switch to see if I still keep blowing fuses.

I FIXED IT!
It was a bad stator blowing my fuse!
I thought I would follow up on this in the hopes of helping someone else that’s been blowing fuses and not able to find the root cause or documentation.
First, I started disconnecting wiring here and there while turning the key on each step of the way. I went thru at least 10 fuses.
I kept blowing fuses until I disconnected the wiring harness that feeds to the engine voltage regulator/rectifier and stator.
At that point, I disconnected the two "AC" wire leads from the stator that connects to the regulator/rectifier.
With an ohm meter, I checked from one of the stator leads to engine ground and read a direct short (continuity).
I removed the stator and bench tested it with an ohm meter again.
The AC leads (field wiring) were shorted to the stator body!
Knowing that to be a bad thing, I bought a new stator for $110.00 and installed it. No more blown fuses!
To swap it out, I had to remove the voltage regulator/rectifier from the engine housing, remove engine shroud/housing, remove ignition module/magneto.
The stator is under the flywheel so I had to remove that as well.
Also, I found a website that has tons of free schematics and factory service manuals.

This is GOLD people!

thanks for coming back and posting what & how you fixed the problem. great job.

Stop it, You're making me Blush. LOL!
I just felt that posting a follow up was the right thing to do.
I see so many forums on cars, tractors, computers, appliances etc., that pose questions and when they figure out the problem, the almost never post the solution.
Very frustrating.
I'm just glad that sites like MyTractorForum exist!
