Onan 4K -12V on starter relay-why is it grounded to chassis?

I'm trying to hook up an ammeter and am discovering there is an additional connection from chassis to battery ground. It appears current is going from the Chassis to the onan generator starter relay ...

The only time the starter relay is conducting current through the chassis is when the starter relay coil is energized. Yes, it is necessary otherwise the coil would not energize.
