## Questions & Answers

**Q: Will it fit a jd lt160 (model m0l160d016178) year purchased 2000? it has a kohler cv460s-26510 16hp engine.**
A: Yes it will fit

**Q: I have to charge my battery every night at dies so fast I thought it was the alternator could it be the stator**
A: I had same issue on my 2005 JD. The Rectifier raised voltage from less than 12v to factory specification of 14.5 volts. No longer have to charge battery weekly.

**Q: Is there a spacer to hold the connections from touching the block?**
A: There should be a female connectors with plastic guards.   Wires should not be able to touch each other... You csn use shrink tubing to fix issue if required.

**Q: Will it fit Kohler ch25-68669**
A: Check your numbers against what's stated on the add for the regulator. That will tell you if it will work right. Most regulators use the same mounting bolt pattern, but that don't mean it's right.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great fit for Kohler Engine/John Deere lawn tractor
*by M***W on April 25, 2018*

I used this product to swap out the regulator on a John Deere LT160 lawn tractor. Upon removing the old unit, I found the inscription read 41 403 09. This part works works perfectly as a replacement. I measured 14.26 DC volts at the battery after installation (12.4V with the old unit in place) and now the battery charges like new. You can test if the regulator is the problem by measuring the AC voltage across the outer two electrodes while the mower is running: if it registers around 22 VAC your alternator is fine. You then check the DC voltage between the middle electrode (+) and ground (-). It should be around 14.25 VDC. In my case the latter test failed and this unit fixed the problem.

### ⭐⭐⭐⭐⭐ Great product, BUT many not be the problem!
*by N***  on April 5, 2020*

Great part, after fixing the main problem! Installed on Kohler command 23hp vtwin on my scotts/john deer tractor. After installing I was hopeful, still no charging output. Checked stator wires for shorts/opens, none found. Switched to AC volts on meter running full throttle, 30-45ac volts should be present on 2 outside wires that connect to regulator, still no output. After removing flywheel found all 6 magnets came unglued and stuck to stator. Turns out this is common problem with Kohler command engines. Quick youtube search later found correct procedure to jb weld magnets back to flywheel IF they are not broken. If they are, sol & new flywheel is $280-300 Once back together found 14.4 volts at full throttle and pto/lights on.

### ⭐⭐⭐⭐⭐ Good Part
*by G***E on October 18, 2024*

Good part works as advertised.
