What a healthy automatic voltage regulator does for your generator.

Why the AVR specials are worth taking now

An automatic voltage regulator keeps the alternator’s output steady as load changes. Without a working one, voltage drifts: motors run hot, electronics see surges, and you get the flicker and nuisance tripping that most people blame on the generator itself. Replacing a tired AVR is one of the cheapest ways to make a set behave again.

Because this is a limited promotion, it is also a sensible moment to buy the spare you have been meaning to keep on the shelf. A generator that is down waiting for a part costs far more than the part.

How to choose the right AVR

Match the AVR to your alternator, not just to your generator’s badge. Check the model number on the existing unit, the excitation type, and the voltage and frequency you run. If you are unsure, send us a photo of the old regulator and the alternator plate and we will confirm the correct replacement before you pay for anything.

Fitting and testing

Isolate the set and let it cool before you start. Note the wiring positions of the old unit, transfer the connections one at a time, and set the voltage trim to the middle of its travel before first start. Bring the set up with no load, adjust to your target voltage, then apply load in steps and confirm the reading holds. If voltage still hunts after a correct fitting, the fault is usually in the sensing wiring or the exciter rather than the new regulator.
