I have a JD5220 that almost started tried again and won’t start, no crank, battery good, all battery connections clean, no dashboard lights. What could it be and how do I check from here?
First thing to check would be if it has any fusible links coming from the battery that might have burned out; next would be the fuse panel to see if it has a master fuse that went.
There are fuses to check. I have the 5520 which is similar. I've got the cab version and if you have the open station fuses will be in a different location. But on mine they're under the left console and under the center steering wheel pedistal.
