Installed on my zero turn, worked and continues to work. Tested charging system with meter after installation and measured 14.6v. Easy to install and no problems since.
Installed on my Dixie chopper with Kawasaki FX730V. OEM part was over 40 dollars. Watched video on Youtube and installed in under 10 minutes. No more charging on jumping battery.
I was so happy to finally get my mower back up and running again after replacing a part. During the repair process, I couldn't help but notice that the replacement part seems to be constructed with significantly better materials and has a noticeably higher quality feel compared to the original product that I had pulled off to replace.
Part was an exact replacement for the one on my Husqvarna YT42 riding mower. Easy replacement. Just remove two wires and two screws and install the new unit. Check your battery voltage before starting the mower - should be around 12.4 VDC. After replacing the regulator, start the mower and idle at full throttle - recheck DC voltage at the battery while the mower is running - should read at least 13.4 VDC - more is better. If you don��t get at least 13.4V then check your wiring and stator output.
Works great on my Kawasaki FR engine.

Works great on my Kawasaki FR engine.
Good price. Correct. Easy to install
Works as it should. Easy to install. Good quality.
No issues with fit, perfect replacement, very quick to install.
Took only a couple of minutes to replace the old one - engine started right up and ran for several hours before I shut it down. Good so far.
Easy to install. Zero-turn Gravely is charging again!
Fixed my charging issue on an exmark mower. Still working as of today
Installed easily and fixed the non-charging issue on my 20+ year old Gravely mower.
Worked on my zt2 mower
Perfect fit for my FR730V and putting out 14.39 volts. No complaints.
Works like original good price fits perfectly on Kawasaki 651v
Two plugs and two screws, mower was charging again.
It took 45 seconds to replace.
