smoked the alternator on 33R887 0033 G1

[TLloyd]

Hello,

This is on a Craftsman T150, made for Lowes or Home Depot through MTD. It is Craftsman Model CMXGRAM1130041. 19 HP Hydrostatic, 46 inch riding mower. I'm feel certain the engine is Craftsman. Model # 33R877 0033 G1.
Forgive me if I come across here as with an attitude. I'm upset with myself, that's all. I greatly appreciate any advice and insight!

This is the only change that has happened on this mower since the last time it was used.

This is embarrassing enough to admit. Don't ask, it just happened - I managed to swap the pins inside the plastic connector when I thought a wire had broken from the pin. Swap - as in now instead of the black connecting to the white it connected to the orange (I don't have correct colors, doesn't matter - it just got swapped.) I connected the plugs, then connected the freshly charged battery. I turned the key, the starter spun but did not engage gears. I knew the battery was correctly connected so I was confused. A strong smell hit my nose then I saw smoke coming from under the flywheel even with the switch turned off! I quickly disconnected the battery but I'm sure the damage was done anyway.

I'm not terribly upset that the alternator got torched as it appeared it had not been charging the battery so I was considering replacing it anyway. If I'm wrong to consider that, please don't tell me.
With a new alternator I'll assume they send the part with the wires in the right order so that problem is also corrected.
I found an online Briggs and Stratton catalog show the alternator part as 592831.
The best I can discover this mower has this alternator and uses a diode to act as regulator (?), it does not have a separate regulator. I'd love to get an official part but I honestly need to save money.

QUESTIONS:
- Could anything else have caused the alternator to get smoked?
- Are there any other parts I should consider as being damaged? If so, how to check for that?
- Can I trust that an Amazon part that indicates it replaces the 592831, has the diode so that it works correctly in my mower?

I should have mowed our property 4 days ago. Even with the lack of rain in south Alabama I am rather surprised at how fast the grass (or weeds) are growing! I'm hoping to get it back running quickly!

Thank you for your time!

Well the JackAs at MTD thinks is funny not to provide wiring schematics or even the wiring harness on this mower.

Disassembling those Amp 1-480319 housing 60620-1 terminals is a little difficult to do without the pin extractor tool. Should had been enough to make someone think twice about doing it.

But normally all you got do is replace the stator and check all the wiring harness for melted wiring. And it kinda hard for someone making an after market to screw it up.

BTW the diode is there to convert AC to a pulsing DC voltage, no regulation. The side of the stator wiring is straight AC for the lighting only.

Try your engine number in Jacks Small engine website. I am not a fan of Amazon.

Sounds like you effectively shorted the charge stator and smoked it.

Thank you for replying.
I thought a wire going into the amp housing terminal had come loose because it was at a sharp right angle as the wire went into the housing. Turned out it was the end of the wire's coating that I was seeing! The wire was still tightly connected. As far as disassembling - if I don't have a proper tool then i "MacGyver" it! You can do a lot with those small "eyeglass" screwdrivers! I pushed in the pin's clip and the pin came right out!
Yes, I got the stator in, put everything together, connected the battery, turned the key then smelled around the flywheel to make sure nothing stunk! No bad smell so I cranked it and let it run - for less than a minute! Turned it off so I could smell around the flywheel again! With my fun luck I was still nervous! All seemed good so I filled up tank then cut grass for 2 1/2 hours. I cut grass another 3 1/2 to 4 hours the next morning so everything but weedeating is done. All seems fine with mower!
Now - for sure! - the battery won't hold a charge!
