PTO Electrical Problem

Hello. I'm new to the forum but am not new in terms of reading or referencing the forum. I have learned a lot here. Thank you.

I own a Cub Cadet XT2, built in 2015. I recently replaced the battery and failed to notice that the poles on the new battery were opposite the poles of the battery I was replacing, and therefore wound up installing the battery backwards. A bonehead move, I know. I'm pretty dismayed by the whole thing. It seems to have caused some damage.

The mower runs ok, but as soon as you pull the PTO switch, it blows the fuse under the seat, and the mower shuts off. The PTO does not engage at all. The fuse blows immediately.

Here is what I have done so far. First, I replaced the PTO switch. After the first time it blew the fuse, subsequently pulling it (with a new fuse in place) produced no effect at all. Therefore I concluded the switch was fried. With a new switch, it now blows the fuse again, but it has not fried the switch (yet).

Second, I unplugged the PTO clutch to see if the fuse would blow with the clutch itself unplugged. The fuse did indeed still blow when the PTO switch is pulled. So the short seems to be coming from a wire, not the clutch.

Can anyone help me further locate the short? I'm not really clear on how to test the wires to see if they have a short. Normally wires short when they are worn or damaged, but this mower is not that old, and the wires to all appearances look normal.

There is the main wiring harness; the dash harness; and the clutch harness. I'm not really clear on what each of those harnesses is responsible for. It seems that I might be able to eliminate one or two of them simply by virtue of knowing what each one does.

I'd rather replace only the harnesses that need to be replaced, as all three of those harnesses add up to about $180. Plus some of it looks pretty hard to get to.

Any insight or help would be greatly appreciated. My grass isn't getting any shorter! Thanks!

Re: PTO Electrical Problem

Sorry to hear of your problem. You will likely need a multimeter to make the job somewhat easier. Then take a look at:

While it isn't exactly your specific problem, there are many great electrical troubleshooting there.

Re: PTO Electrical Problem

Thank you for the link Flaken. I will read that. And yes, I agree, I am going to get a multimeter.

Does anyone happen to know where I could find the wiring schematic for my tractor? The model number is 13BGA1CS010. It's an XT2, with a 42" deck and a Kawasaki engine, built in 2015. I have tried really hard to find the diagram using Google, but I've been unable to find anything that is for sure the right diagram. Thanks for any help.

I don't know the search terms you used with Google, but I used "cub cadet xt2 wiring schematic diagram pdf" in Duck Duck Go and those were in the top ten, or so. Duck Duck Go is an alternative search program that doesn't track you.

There may also be one in your owner's manual.

I've used DuckDuckGo and it's good, however my wife likes to use McAfee Web Advisor on her personal login and it's is not supported with DDG unfortunately.

Re: PTO Electrical Problem

When you first attached the battery did you get arching and sparking and realized your mistake, stopping there?
Or did you attach the battery and then turn the ignition switch to try and start it?

Reading this I keep thinking ignition switch is bad. Can't tell you why, but would be first thing I would check.

Should/could be a table in the wiring diagram showing which connectors internally make contact in the 3 different switch positions. Can take it out and test it with the meter. Or with a 12v battery and 12v bulb. Something could be shorting inside if it got damaged.

Re: PTO Electrical Problem

That switch should certainly be suspect. The ground terminal became the positive! I'm also suspecting the VR with juice flowing the wrong way through it. Who knows what might have melted causing shorts.

Re: PTO Electrical Problem

Thank you guys very much for the help. The Parts Diagram that shows the electrical parts, I had seen that. The other diagram, the schematic, I am unable to read it---the writing is so tiny; when I zoom in, it gets super fuzzy. I tried printing it, thinking I might be able to look at it with a magnifying glass, but its resolution just isn't very good. That is the only schematic I have seen. I've used search terms such as "Cub Cadet XT2 wiring schematic." or, "Wiring diagram." I also tried searching using the model number. My manual doesn't have a schematic.

To answer your question, JP, I didn't realize the battery had reversed poles until I removed it to put in a different battery. I had tried to start the tractor with the battery reversed.

I'm a bit confused. How could the starter switch be the source of the short? When you pull the PTO switch, is something involving the start switch affected?

Where all does a ground circuit on the battery typically go?

Thanks again for the help. I really appreciate it.

Re: PTO Electrical Problem

Leo L, what you may want to do, is to contact Parts Tree via email or a telephone call and inquire about the difficult to read schematic. One of their people may just send you a clear copy. Never hurts to try.

Starter switch can be overheated and melt some of the plastic inside. Allowing metal to metal contact when it normally should not contact. Hence creating a short condition.

Ignition switch is what controls power on and off to where the power is needed. Ignition switch in ON position sends power to a relay that in turn gives power to the PTO switch.

You need to test ignition switch with a multi meter in all 3 or 4 key positions to see if contacts listed make contact when they should, and not contact when they should not.

Problem is, as you stated, the schematic drawing is too low of a rez to be able to read it. I downloaded it and tried to enhance it some, but no joy.

Negative from the battery runs to frame, then through all metal parts of the tractor unless insulated from ground. Also sent via wire, or metal contact, to different switches. When positive is attached to frame, you have reverse polarity. Somethings will run OK with reverse polarity, others will not.

I think we need to find a better schematic for you to follow.

Re: PTO Electrical Problem

Hey guys, thanks again for the thoughts. The damage seems to be worse than I had hoped, even. The brand new battery is now dead. Previously it would still start and run, but would blow the 20A fuse under the seat when you pulled the PTO switch. Now the new battery is dead, so it won't even try to turn over.

What a disaster, from such a simple mistake. Now I need to start finding Kawasaki parts in addition to the Cub Cadet parts. Looks like the VR is probably bad. There's an alternator in there too, isn't there?

Do you happen to know what portion of the numbers on the label on the engine constitutes the model number of the engine? I've tried inserting various portions of the numbers into a Kawasaki parts finder, and none of them work. I'll attach a picture of it here.

Thanks for any help.

Leo

Re: PTO Electrical Problem

OK. I found a different sticker near the front of the engine. This other sticker appears to have the engine number.

Re: PTO Electrical Problem

One of the websites we use most often here is Parts Tree. On the page at Parts Tree for your XT2, it lists the Kawasaki engine and parts for it. Appears to be a FR series engine by Kawasaki.

Re: PTO Electrical Problem

Be certain to get that new battery on a charger (Low Amp) right away. If the battery is good, it'll hurt it to be in a "down" condition.
