The key here is the 304 code low battery voltage. Check the emergency disconnect switch the fail,all the time specifically the micro switch on the bottom, this fails then takes out the main switch. Change the eds and I can near as dammit guarantee it will clear. My advice is scrap the truck lol the WT is prob the worst crown truck you'll come across
