Troubleshooting failed solar - Water in your junction box

Well, not sure exactly what fixed things. But its working now. I took apart all connectors, put them back, put fuse to the battery, put fuse in to the solar. It all connected up and worked fine. I will put the dielectic on. I am still perplexed. But happy its working. I imagine taking apart the connections and resetting them, especially in the junction box, might have done it. Thanks for everyone's advice here. I find this forum very useful.
