Question about Ultra Products Guardian Ultra Source 17,500 Watt Emergency Power System - 4583

1 Answer

I have a slight power surge on my 15,000 ultra source

I noticed the lights diming slighly. I went to check out the generator and noticed a slight surge in the engine so I disconected all power had no change. The generator is at my Camp house and is only run about one or two week ends (4-5 hour at a time) in a month.I removed the breather cover and noticed the linkage on the controller moving slighly.I changed spark plugs and still no change.
My Brother in law has practicaly the same unit as a stand by generator on his home. He said he notice his doing the same thing.
I keep my generator serviced more than the book calls for and I keep stabil in my gas to keep it fresh.

Starts up but will not run but for a few seconds

Check the oil. Some engines will shut down if the oil is low. Otherwise you probably have a dirty fuel filter and the carburetor fills up with gas long enough to start but isn't getting enough gas to keep it full.

The current starter battery is not recharging. I would like to know if there is a problem with the alternator or battery charging mechanism. If so, is there a replacement part available ??

Hi Frank,

Have you charged the battery and see if it holds a charge? If it does, then it's probably your alternator.

I hope this helps. If it does, I'd appreciate your vote. Thanks,

Fuse blows repeatedly

The auto speed control is failed. Keep it manual and see how it does...It will run at full throttle even when no load is running. Then fix the throttle control when able.

Have you checked the fuse? Mine keeps blowing the fuse (located on the back of the control panel) with each startup and shutdown or use of idle control.
