SOURCE: generac 20kw - new battery dead, twice. is there a
if this is a standby unit. there is a charger built into the control box. check the fuses. if it still blows the d\fuse you can install a float type charger available from most auto parts stores. make sure there is power comming in from the bldg breaker box.
Testimonial: "what you say is correct, however, we have checked your suggestions and the unit still will not keep a charge. we have now put a trickle charge on it"
SOURCE: battery does not stay charged on my 20kw generac
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.....

It is always good to install a large enough wire where the maximum load can be drawn plus a little extra for safety. 7 gauge wire will do, if it was mine I would use 6 gauge wire. If the length is over 20 feet but not longer than 80 feet go to the next larger size wire.

Manuals can be downloaded from this webpage but the model number you quote doesn't give any results ?

Look for a fuse that protects a transformer that supplies the rotating field voltage. If fuse is blown, find a rectifier module that the transformer drives. Likely the rectifier has a shorted diode. Fix before replacing the fuse.
