Calling on Solar Techies
I have been thinking of going solar for some time and decided to pull the plug. My wants are a 400 to 500 watt system. I have four 12 volt batteries with 340ah. I am not planning on changing b...

Wiring!
I have a issue at my wiring and Shunt that is just confusing maybe you guys have some ideas.
I wired my Monitor shunt inside the battery box with the batteries. I connected the battery side of the shunt to the Negative side of Battery (4).
I connected the Trailer Frame Ground, Inverter, Solar Charge Controller and a 12 volt accessory to the Load side of the Shunt.
When everything is connected there is no problem.. BUT when I disconnect the grounds from the Load side of the shunt
With a test light connected to the frame of the trailer
In this order
I remove the charge controller ground.... Nothing
I remove the trailer frame ground....Nothing
I remove the inverter ground and I get a 12 volt short to ground. According to my test light the entire shunt becomes energized. I'm also able to get a circuit with my test light connected to the frame and touching negative battery terminals.
At this time only the battery side of the shunt is connected.
Also I have tried
Cutting circuit breaker power from battery to trailer
Cutting circuit breaker from charge controller to battery
Cutting off power switch from solar panels
Removing fuse from Inverter
And it still occurs.
Put all back together and no short?????
Any thoughts?
