There is no problem with it
It happened to me on my 2005 JD as well. This device increased the voltage from less than 12 volts to 14 volts, which is the factory specification. This charger has a 5 volt output. It is no longer necessary to charge the battery on a weekly basis.
Connectors should come with plastic guards and a female connector. A wire should not be able to touch another wire. In case of anything going wrong, shrink tubing can be used to fix it.

With this product, I replaced the regulator on John Deere LT160 lawn tractors. The old unit had an inscription that read 41 403 09 as soon as I removed it. I can use this part as a replacement with no problems. 1. 4 is the measurement I took. The battery, after installation, has been measured at 26 DC volts It was charging at 4V with the old unit in place before) and now it charges more quickly. Measure the AC voltage across the two electrodes on the outer side of the mower while it is running to determine whether the regulator is the problem The temperature should be around 14 degrees. A 25-volt DC power supply is required. I found this unit to be effective in rectifying the failure of the latter test.
The installation is straightforward. I found it to be the perfect fit. It charges at 14 mph now when my 20 year old John Deere LX255 lawn tractor with 15hp Kohler engine was supposed to charge at 15. A battery with 5 volts vs a battery with 12 volts. Whenever I engage the mower PTO, I get only 5 volts and the charger light does not come on. It would be nice if it lasted. I am very happy with the installation after the Thus far, it has proven to be a great value. br>Edit your sentence. The rating has been changed A shorting incident happened when the exposed contact on the center where battery power is constantly being drawn shorted to the metal Kohler engine cover after 3 months of use. As a consequence, the stator was destroyed and wire connectors and a couple of wires were melted. As I was trial fitting and testing the replacement which also shorted for a brief instant as I tested it, I figured out what was wrong. This part is installed over the engine cover hole over which the contacts project slightly. The contacts just touch the edge of this engine cover hole. To distance the replacement component from the engine cover, I used a few washers as spacers on the mounting screws. In order to protect contacts exposed to the elements, I covered them One possible alternative would be to bend the contacts to prevent this issue, and with plastic engine covers this should not be an issue. In the event that a Kohler original equipment part is not available, this part will become a spare.
I installed the device and hoped for the best, but it still didn't work. I checked the stator wires for shorts/opens, but did not find any. Using AC volts with a 30 mph engine running at full throttle on the meter The output voltage of 45 ac should be present on both wires connected to the regulator, but there is no signal. Upon removing the flywheel, I found all 6 magnets had come unglued and were stuck to the As it turns out, Kohler command engines have this issue as well. The correct procedure for jb welding magnets back to flywheels IF they are not broken was later found with a quick You Tube search. Please let me and Sol know if they are An additional $280-$290 is required for a new flywheel As soon as everyone was back together, 14 was found. When the throttle is fully extended, 4 volts and the power on indicator light is.
It seemed to be the most likely component to give out, so it was replaced first. In my bench test of the old regulator, it presented as an "open" in both directions, which indicates your old regulator had either failed diodes or several If you are using a multimeter, set the Ohms to the highest possible setting, and check continuity between the center and the outer poles, as well as between all poles and the A zero connection or infinite resistance between all poles is an indication that the meter should not have worked. I can run my lawn mower and charge it now without any problems!.
I installed it in my Kohler Courage 22hp engine in my The charging problem is now fixed and the second season has begun. To find out how to use a multi meter to test your old one, look on YouTube. test that can give you a fairly good idea of how your charging system is performing is to take a voltage reading at the battery posts while the engine is In the case of an uncharged battery, you will see 12 volts. The price will gradually fall once it reaches 8 or so. If the charging system is working correctly, the voltage should be approximately 14 volts.
If you wish to inspect the regulator, you should look for a design flaw. In the case where you have a metal shroud on your mower like my Kohler engine, then the terminals may short out. As I was hooking up the battery I noticed some sparking at the battery terminals, so I caught it in time. Unlike the original regulator, the original regulator has shorter terminals and a plastic spacer in the back that keeps it away from the shielding. It would not be a problem if your engine had a plastic shroud. I hope I didn't damage it in any way because so far it seems to be working fine*.
At 14, it is now charging. The battery should have a voltage of 5 volts. We will have to see how it fares since other reviews have indicated quick failures. There were probably just a few bad apples in there. It even came with a bottle opener keychain! You win!.
It's been working on it for two months now, but I don't know how long it will continue to work. This engine has been running for about 40 hours.
