24V AC hour meter on generator

I'm also surprised that the meter uses that little power, as well as impressed. I see zero safety risk with this. Even if the meter were to be a dead short, I crunched out that the resistor would be dissipating about 0.06 watts. I'm paranoid about things like this and generally would put a small value glass fuse in series with the whole thing, quarter amp or less. In this case however, if the meter is mounted on the generator with short wires, I'd probably skip the fuse.
