DCDC Charger not putting AMPs through Shunt

Hey Guys, I've got a DCDC 30Amp and a shunt. The shunt isn't showing any positive feed as the dcdc is turned on only a negative reading as the fridge and amp is working. It will go positive when the solar turns on so I was wondering why wont it when the dcdc is on. May it be wired incorrectly ?

It has a positive from main starter into dc dc and negative413348237_368613772431317_5840239327774034026_n.jpg out of dcdc to the shunt which than goes to 2nd battery. The positive out of the dcdc onto the 2nd battery. image_2024-01-19_131125787.png

Do you have a negative connection from the 2nd battery to the chassis?
