Calling electrical gurus

wnjj,

Battery is connected to the system for sure. At least the cable are connected, whether it's sending current into the camper is a different story. Obviously some is wrong between the battery and the camper that's what I am asking assistance for. I know all my cables are installed tightly onto the battery post. How can I test if I am getting power into the camper?

Kettner,

Where is the circuit breaker near the battery, is it visible? I don't recall ever seeing one in the outside battery box. I'll look again as I might of missed it.


WNJJ.

Battery is reading 12.79V at all times, with shore power and without shore power. Lights are no existent without shore power, but power up with shore power. Same with any other appliance... No good without shore power and good with shore power.

I checked the output that the converter and it is reading 13.79V. Not sure if that helps the group.

Do you have a battery cut-off switch? My Eagle Cap has one. It sounds like your battery isn't connected to the system at all. If your system is showing that it's "charging", that likely just means the converter is above something like 13V. That will be the case even just running lights off the converter.

one good thing is that Lance is located in Lancaster just NE of Los Angeles, if you get stumped you can drive there in an hour or two for help.

Does the battery act low? Are the lights dim? Does the water pump or furnace fan run slow?

You have an open circuit between the battery and fuse panel.
Somewhere you will find 12.79 on one side and zero on the other.
Clean, tighten, repair, adjust or replace the item not passing voltage.

My first guess would be a circuit breaker near the battery. Voltmeter will tell the story.

Duplicate. Please delete.

Take a volt meter and measure from the panel that's alarming on low voltage and confirm there is a low voltage. Then measure the same spot with shore power attached. If you truly do have low voltage at the panel when shore power is disconnected, then trace that wire back to the battery, measuring along the way. Be sure to use the same ground on the meter as you trace the hot, positive lead.
If that checks, then start checking the ground wire circuit from the panel to the battery negative lead.

I suspect you have a faulty ground between your battery and the panel, making the panel think you have low voltage.

Hmmm, obviously there's a problem. Personally I would be on the phone @ "0"dark opening time @ Lance and if you can't get through leave a message and call back if you don't hear back. Additional options as the previous poster said, would be to start checking along the main conductor & side conductors. Sounds like you may have a short some where. Wish I could be of more help. Best wishes and please let us all know what you come up with.
BTW: My own experience has revealed some stange "quirks" with the monitor panel that we have at least.

I would start with the house monitor panel and check what voltage you are getting there. It could be a bad panel board, or the connections are loose, or you have a poor ground. Start at the problem and work forward as you know the battery is good, someplace along the line you have a major voltage drop.
