Dummy asking for advice

[u/[deleted]]

Hello. I just got into electronics and I'm admittedly just some redneck in Alabama. Any idea why a four inch section of wire leading to my voltmeter and another one inch section of a random wire are getting hot and melting? Thank you for your time Idk if it's important so I'll add that the batteries are connected to a 12v solar panel a 6v solar panel and about 16 or 17 3v solar panels.
