have a scag fixing for a good friend.. have nothing when turn key on. first time i did i had a slight flicker on ammeter but now nothing at all.. 2 fuses beside seat are good all safety switches are functional and i have replaced key switch and relay and pto switch and electronic module is on the way.. i have 12.7 volts coming into key switch housing.. i seen on schematic there is another 20 amp switch in the back near battery but have not seen it on the mower.. i have also heard that even though the battery terminals look good it could be a bad connection... this mower is dead in the water.. does nothing at all.. also the friend parked mower sideways on a hill wondering if that could mean anything.. thanks
