Help identifying wires, please
I have 3 white wires coming from the junction box under my camper. They transition into a black wire that ends in a ring terminal. I have no idea where this wire goes. I don't know if it's a ground...

Most RVs the techs who build 'em were taught to wire by House standards where White is neutral. so they wire white to negative.
If you have white wires comign into the box and a big black with ring terminal
ODDS ARE.. and I tress ODDS cause there are no guarantees.. Ground.
Your meter is your friend... Clip the black lead of a volt meter to the ring terminal and find the companion positive wire Then plug in (making sure the terminal touches NOTHIHG other than the meter lead, or rather nothing conductive) and see what it says. 13.6 Excellent. but if it says -xx.x somethign is bass ackwards
ohm testing is good too IF you know how to do it But on many RVs the positive wire will show near zero ohms to ground.
