Ditto. Where these came from in Japan, some tractor fleets must carry one battery around to start all the tractors for the day. My older YM240 manual says just leave the key in the off position after starting, if there is no battery present - as if that is normal operation!Honestly if your tractor starts and you keep a charge in the battery with a charger I wouldn't worry about the light till it was 80 degrees out. Won't hurt a thing. Especially if you want to use it.
Once started you don't even need the battery.
The voltmeter you get will tell you if the voltage at the battery is greater while running (charging) compared to engine turned off. If you see higher voltage while running you don't have a problem at all, aside from a useless indicator bulb.
