I have a 99 Generac portable generator mdlP5000, 5000 running watts 6250 surge watts. I recently had to replace the carb and after doing so I decided to measure the L1, L2 voltage outputs without a load and found that L1 varied from 119.2 - 122.0 volts and the output of L2 varied from 120.2 - 125.1 is this considered normal?

I also wanted to ask if anyone knows, when they rate surge watts what the duration would be, in other words how long can the generator handle lets say the maximum 6250 watts?

Any info would be appreciated.

Thanks

Bill

Hello bill
The readings your getting from your generator is within the appropriate range. This is known as nominal voltage. However the fluctuation over a short period of time leeds me to believe the engine powering the generator isnt running as smooth as possibe.

And for the second part you your question the surge rating is for inrush currents. Anytime an electric motor or fridge compressor starts it draws an extreme amperage for a split second.

Hey Josh,

I'm still in the process of fine tuning the carb, but in all honesty the Tecumseh HM100 never ran that smooth from day one. Considering it's age and hours on the unit I can't complain if it isn't as smooth as possible, but I'm going to try to get it as close as possible.

Thanks for the response it's much appreciated.
