Power Problem

1. Power is coming in to the 110V box and supplying the air conditioner, but the wall plug ins are not working.
2. There is no power to the convertor box so all of the 12V things are not working. However, if I place a battery charger on the battery then the 12V items are working, i.e. lights, range hood/light, the furnace, etc. Also, if a jumper is placed from the 110V box to the convertor then the 12V items work. Any ideas would be greatly appreciated.

Thanks,
Ron

Hi Ron

Can't help on the wiring diagram but might on the rest.

So you AC but no wall outlets.

And you have battery and 12 volt lights but no convertor 12 volt

But then you put a jumper between something and the 12 volts works on the convertor.

Well the good news is the battery and 12 volt bus side is all working. But the convertor hooking has questions as well as the plugs.

Tell me about this jumper. Where does it jump from and to? Are you hot wiring up the convertor directly and that is what is working?

If so this sounds like maybe you have a fuse/circuit breaker issue on the 120 incoming line that feeds the plugs and convertor. If this has breakers, it may have bounced out of the 120 buss bar and is not making and the plugs and the convertor power up and they might be on the same circuit.

Are you electrically handy and have a volt/ohm meter?

Some how you or someone else is going to have to go hunting in the 120 side of the convertor box. Pull the shore power and battery before hunting.

Let us know some more on the problem. Any chance if a pic of the inside of the convertor? I can then see what you have and help more.


And 88 Fifith wheel Welcome to the club.

John

I will try to post a pic tomorrow. The other night my uncle and I ran a jumper from a wire in the 120 box, another from the circuit breaker that we believe is the convertor side of a double pole breaker, to the in lines on the convertor. When he hooked up this jumper I plugged the camper back in. He said he heard a pop noise, and then everything was working on the 12V side, so we figure the circuit breaker is good. He had also checked both poles of the circuit breaker and there seemed to be continuity through both poles. We will be working on it again tomorrow, so I'll let you know what we do, and maybe try anything else you can suggest. Thanks for your help in this.

Ron

Hi Ron

H'mm hard to tell what you have. A pic here is worth a million words.

Take a nice close up of the full convertor/120 panel that fills the 640 x 480 scree size on the outside of the convertor box. Sort of like this.



Then I can see what it is you are up against.

Your on the right track. If you hot wired the convertor then you are going to have to back track to why it is not fed from the 120 incoming line.

I do not know that vintage you have. But on the one like in the pic above, that breaker pivots in on a bus bar to make the connection to the 120 bus. Just like in a home breaker box. If that connection came loose or had crud on it, it might not make the circuit But yet a continuity test touching a good part of the "in" side might work.

I guess a question is, does 120 VAC come "out" of the breaker feeding the convertor? I think not or why else would you be hot wiring it. If not, then keep going up stream on the breaker and find out where the power is and then is not.

Good luck and keep us posted.

John
