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 ...

I always try to put shunts (amp meters) in the positive lead, there is almost always more then one ground path. The converter 12 volt ground may be grounded through the AC ground as well. There may be leakage in the fridge and water heater circuits to ac ground also - usually these would trip a shore power gfci.


Which ammeter do you have that works?
