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 back to the -12V on the battery.
Is there any reason that the genset is grounding the 12 volt to the chassis? Is this necessary?
I'm not certain but I'd imagine this would have some impact on my ammeters accuracy as their are multiple paths to ground. My ammeter was hooked up only on the main -12V going from the batter to the RV fuse block.
Is there one or 2 wires from the battery post to ground? There should be only one. Your ammeter should be hooked up in this one wire. Other things are connected to ground and do not affect the ammeter.
