Question about Generac Guardian Series 5502 10 kW Emergency Power System 5502

1 Answer

Hi: I have a model 0052411 Guardian generator that is putting out 170 volts. Anyone have any idea what has caused this to happen. It has fried any transforms that are in the house. Generac is not much help. Let than 50-60 hours on the unit. Most likely the voltage regulator. Thanks

Check the automatic voltage regulator .Or if you have a bad neutral connection one leg will be very high and one leg low causing damage to sensitive equiptment.

    Thanks Dan:
    Yes it was the voltage regulator. But my question was more to why there was not a fail safe sensor to shut the generator down. Why not a high voltage sensor?

Not knowing which model youa re talking about it is tough. Obviously NEVER wrap foil around a fuse ! All I can tell by your post is that power is on the fuel pump all the time now, I would say that you have damaged a control board.

The battery is overcharging either by the external charger or by the engine alternator. This is causing the battery to "boil" realeasing hrdrogen gas. One spark or high current demand from cranking can cause this. Have it checked by a pro

Battery does not stay charged on my 20kw generac generator


WAS A 110 VOLT CIRCUIT RAN TO IT FROM THE NORMAL UTILITY POWER OF HOME OR BUILDING IT FEEDS?
NORMALLY THIS IS DONE IN A SEPERATE CONDUIT FOR CONTROL WIRES.AND THE FEEDERS ARE IN ANOTHER CONDUIT.
WITH A DIGITAL TEST METER,CHECK FOR 120 VOLTS AT THE BATTERY CHARGER IN THE GENERATOR CABINET.USUALLY THERE IS A RECEPTICAL TO PLUG THE CHARGER INTO.
IF VOLTAGE IS PRESENT AT THE BATTERY CHARGER AND INDICATOR LIGHTS ARE ON, CHANGE METER TO DC AND CHECK FOR 13.8 VOLTS OUTPUT FROM THE BATTERY CHARGER.IF YOU HAVE OUTPUT VOLTAGE TO THE BATTERY,AND IT IS DEAD,CHANGE THE BATTERY..

HOPE THIS HELPS YOU,BEST OF LUCK.....

I have never heard that generators need to be perfectly level to prevent generator damage. It doesn't compute -- auto generators/alternators run at all sorts of angles -- so do motors. And for the damage to occur in 2 hours running doesn't sound right either.

It does sound like the generator itself is not working/generating properly, but I doubt it was caused by the slab.
