Zero complaints. Works perfectly.
The vehicle: Craftsman tractor circa 2006 with 42 inch deck, 24 hp Intek V twin engine and ammeter. The problem: The ammeter gauge read close to zero at idle, and -5 amps when the electric blade drive clutch was energized. Clearly, the charging system was not operating properly. The diagnosis: I disconnected the voltage regulator two plug connector, started the engine, and checked for voltage at the alternator side of the plug. I saw roughly 18V (volts) at idle and 27V at max rpm. This confirmed the alternator itself was functional. More testing should have been done at this point, but for 12 bucks and with 2 day free shipping...I took the chance and purchased this voltage regulator. The fix: Installing it was simple as two bolts and two wire connectors. Here's a tip: make sure the metal body of the voltage regulator is bolted firmly and directly to the metal shield it attaches to. Must be metal to metal! And then, make sure the metal shield is firmly and directly bolted to the engine. Again, metal to metal!! The voltage regulator does not have a ground wire; it grounds directly to the engine through the shield and bolts. Regulator won't work if it's not properly grounded. Verify repair: Started tractor engine. Immediately saw ammeter readings of 5-7 amps on gauge, indicating a properly functioning charging system. This particular voltage regulator looks, feels, and performs like a factory one for significantly less money. I have tested with about 3-4 hours of use, and no problems at all. WELL worth the money!

Works great
The voltage regulator on my V twin vanguard was broken only putting out about half to 1 V I replaced it with this new voltage regulator and it works flawlessly it plugged directly in bolted right up and at idle it’s putting out about 13.75 V and upwards of 15 at full rev which is perfect

Works great
I was having a charging problem on my dys 4500 and this fixed it. The mower was reading 6 volts while running before and 14 volts after I changed the part.

Works great
It was an exact replacement for the regulator on my Poulan. I was having battery issues and this solved it immediately. No issues with installation.
