Hi, I've been running my portable genny, a briggs and Stratton Power Gen 3400 for a 3 hours a day for the past 2 weeks while I rebuild my old diesel one. I;ve had no probs with it until today when it kept blowing my one lamp and made the TV smoke!!!!!!!!!!. I checked every thing with another genny and all was ok so, its got to be the Power Gen. Would it be the voltage regulator? If so, how do I get at it?

Cheers, Spud

Is it possibly a governor problem? Have you got the choke on? If the engine is running faster, it'll produce a higher voltage.

Check the voltage and maybe adjust the throttle once its warmed up?

Doubletap, are you running it under a decent load? We have been very fortunate with ours (GMC) as it has run everything we have tried. Just remembered, the digital radio doesn't like it. We have found that the sine wave output varies considerably with the load. Can you get hold of an oscilloscope? It may be just that your diesel unit has a better regulated output.

Some smaller cheaper gennies run better with a better smoother output if you have a 100 watt bulb on whilst using it. Now I know that will eat into the power available & they wont be available for much longer but it does work.

Hi, thanks all. The small petrol one was running great for about a year, maybe only 40hrs a week. Guess I'll have to take it to the local workshop and get it tested.

Thanks anyway.
