12 volts not getting to the converter

The battery and fuses are good. I tracked voltage to a junction box in the front corner, but nothing shows up on the wire going into the converter. Is there a wiring diagram avalible? I have a 2014 Coachmen Clipper 17bh annaversary edition. There is no circuit breaker from the battery to the junction box, nor do I see one from the junction box to the converter.
I'm stumped

Are you sure you're talking about your converter?

110vAC goes TO the converter.

12cDV goes FROM the converter. 12vDC goes TO an inverter.

As I understand it, both 12v and 120v ac go into the "converter". It acts as a battery charger when 120vac is present, but also is the fuse box and distribution point for the 12v systems when on battery power.

Yep, 120v AC comes into the converter and 12v DC comes OUT of the converter.
And a wiring diagram doesnt exist. You can contact Coachmen about one but I doubt they have one.

Uhhhh, not exactly. What it sounds like you are describing is a distribution panel, which the converter is a separate component. Many times the converter will be below the distribution panel (But not always)


It seems like you are possibly confusing the converter and distribution panel, and their separate functions.

What issue are you trying to resolve? Converter not charging the battery? Lights etc. not working when plugged into shore power? Lights work on battery but not shore power? If we know the issue we might be able to make better suggestions.

See the bottom figure in the first doc.

Then read the second doc.

The Converter only takes 120VAC and converts it to 12VDC, the converter is often a part of the Power Control Center where the 12VDC Fuses and often the 115AC circuit breakers reside.

Thanks everyone for the help. I found the problem. It was a bad ground wire. Inside the junction box, many white ground wires were crimped together in a ring connector. That was corroded and also where it bolted to the frame was rusty. I cut off and replaced the connector and cleaned the frame. Problem solved

Your solution will cure a lot of 12v problems. My 12v frame ground has bitten me twice in 5 years. Clean and reattach with protectant.
Thanks for posting your solution.
