Flooded batteries if that is what you have vent corrosive fumes so check everything. Even shrink wrapped battery wire can/do fail between the wire and connector.
Shook the wires and it came on. Did it again and lights are back on. My first thought was the connectors but that doesn’t make sense from the original problem where I had power 4 feet away at the junction. Any ideas on what to check or replace?
One cheap and clear way to isolate is to completed clean the battery posts and replace the connecting cables. Or using long leads between the post (not the connector) and the far wire end and check for a connection with a voltmeter. Better yet buy a DC clamp on ammeter, leave lights on and check for current to isolate to a wire.
Intermittents can be hard to isolate.
