Easily to install
Had my Harbor Freight 4300 watt generator for about 4 yrs with little use but had been very dependable until I kept blowing the GFI, well after some searching I took a chance & ordered this voltage regulator. Easy to install & it works PERFECTLY, great product.

Turns junk back into a functional generator
Generator quit making power one day.Tracked it down to this part.Bought this replacement, generator is back making power.Much cheaper than a new generatorGet two, put the second one somewhere safe.

Saved my generator
My generator was producing little to no power… it was almost new, the engine worked great, but didn’t produce power. I bought this product after watching numerous videos and talking to many “experts” about running a drill backwards for restoring a proper magnetic field. I wish I’d known about this product, it took 10 minutes, fixed the problem and worked great. Hopefully it lasts.

Worked for ONE day and then almost destroyed generator
I received this AVR yesterday and had it put in. It ran from about 5-9 PM yesterday with no visible problems. I went to start the generator at 10 AM today. It ran for 10 minutes then suddenly shut off power. I went to investigate and found that not only had this connection burned through (at HALF LOAD), but it had started to burn other components around it before the safety feature kicked in and shut it down. I'm lucky it didn't destroy my generator completely or start a fire in this drought.

Sportsman Sandstorm 4000/3500 watt
I took a gamble to see if this would fit on my Sportsman Sandstorm dual fuel generator. The bolt holes lined up perfectly and it had the same rating as the original part. I did have to “flash” (restore the residual magnetism, the drill trick worked) the coils after installing. I simply plugged a drill into the 110v with the generator running, out the drill in forward and spun the chuck in reverse by hand and it started right up. This AVR should fit a large variety of generators given a lot are made by the same company and just have different paint and configurations.
