my neighbor swapped his grizzly 550 battery and now the dash just shows a big "E" nothing else no other lights or codes pretty sure that's not normal anyone know what's causing this or how to reset it looking for fixes that have worked before

Yeah, that big E usually means there's a communication or electrical fault, often tied to low voltage or a battery issue. Since he just swapped the battery, tell him to double check all the connections, especially the grounds, also make sure the terminals are clean and tight. If it's still showing E, try disconnecting the battery for a few minutes to reset the ECU. If that doesn't help, it could be a blown fuse or something got shorted during the swap. Seen it happen more than once

It's electrical yes. Usually it's due to bad connection in the battery swap. @diplomaticdave said all of the deets you need like correct the voltage and fully charge it btw. Check also the fuses if there are ones blown. Also get a scanner for yourself so you know for sure and we also know what exactly we can say to help.

yup, it's definitely a battery problem. you should check if it's properly connected and secure. also check if the terminals are clean and not corroded

Hey! So, the "E" light on the dashboard typically appears after you change the battery and might indicate a fault code or some kind of electrical problem. I recommend starting by checking the fuses,blown fuses can sometimes trigger this. You can also try resetting the display. Just turn off the ignition, hold down both the "SELECT" and "RESET" buttons, then turn the ignition back on while still holding them down for around 8 seconds. If that doesn't do the trick, you might need to look for error codes in diagnostic mode or reach out to a Yamaha dealer. Let me know what you find out
 
Left my lights open for 2 days so my battery died, after jumpstarting it and going back to life, this letter 'E' never disappeared ever since.

That "E" means voltage or ECU glitch but that's only due to the battery so you have no major issue right there. Try to disconnect the battery then reset the system after a couple of minutes. If that doesn't work, go to the dealer.
