miller bobcat 225 not starting

[6.0ramon]

I have a newer miller bobcat not starting. When I flip the switch on the hour meter it lights up like normal but when I turn the switch all the way to start it won't start and when I let go of switch the warning light on hour meter lights up. I checked gas and battery and oil and everything but it still won't turn on

Generally its either the battery or a corroded harness connection left side inbetween the engine and firewall.
