Could also be the controller or even wiring.

To check the panel: Look up the specs. Then locate the panel wires (not the controller output wires), disconnect one and then with good sun check the voltage which should be very close to Voc (open circuit). Next short the 2 wires and the amps should be close to Isc (short circuit). These 2 measurements are a very good test of a panels performance.

How new is "new"? Is it under warranty? If so, don't touch it!

Ok, I don't wish to appear dumb but if he were to short the two wires from the panel, where would he place the meter leads. When shorted it would appear to be a close loop.

Our '19 NL has the solar controller output, jacks, converter output, and the fridge (supply current for the DC boiler heater only--not the fridge DC control circuits) wired directly to the battery via 4 different leads (ours are labeled). There are resettable fuses for most (if not all) of these 4 circuits/leads located directly above the batteries. Just trace the leads back to confirm. None of these circuits/leads pass through the DC/AC fuse/power panel inside the camper. Hope this helps.

Using a volt meter at the solar charge controller what voltage if any do you see on the solar terminals and on the battery terminals?

When you say the "solar panel is not working", is this observation based on the LED and LCD indicators on the front of the Enerwatt EWC-30 solar controller? Or, did you make some voltage/current checks?

got it fixed the fuse, was behind board thanks guys I have had two previous truck campers then a class C then the wife had to have a 40 foot diesel A. Then she finds out our favorite places in the mountains have a 35 foot limit, of coarse it is my fault, she picked the 10-2 EX CD SE dry bath Northern Lite over the 2500 10.4 Bigfoot I do not know all the why's, the Bigfoot has a much nicer layout and hands down a better dry bath and it was 4K cheaper the only extra the Northern Lite had that the Bigfoot did not come stock with was one solar panel. And I told her the Bigfoot is already wired for solar. (for 4K I could have put 400 watts or more on the Bigfoot) Then she told me but the Northern Lite has a slide out pantry. Ahh, but the wife is happy , I am very sincere in saying thank you to all of you that helped me with my truck camper questions and solving some problems. Hope I can some day return the kindness and generosity of your time that you took to answer and help me thank you, thank you

I use a AC/DC clamp on ammeter to measure amps, just clamps around the shorted wires. It also measures voltage, ohms, etc. Or use an ammeter on the wires and many meters have 10A capability.
