110 V System Failure

[Roger101]

I have a 2018 19ft Bambi. On the way back from the Yukon, the 110 v system no longer worked. I can use the 12 v system to get all lights, pump, etc, and charge the battery from the tow vehicle, (so I do not know when the problem occurred) but attaching the shore connection does not allow anything to work, including battery charging. The red LED light on the inlet cord lights up, but the adjacent green LED light on the outside connection point does not. I appear to get 110 volts to the 110 panel (at the 30 amp breaker), according to my tester, and on the inlet to the individual 15 amp breakers, but none of the 15 amp breaker outlet points appear to have voltage. None of the green fault lights are on, and flipping the breakers does not change the situation.

Has anyone any expertise or history of this?

Hi

Well, assuming that your measurements are correct, the answer is fairly simple - all of your breakers are defective / broken. A breaker is a pretty simple beast, either the circuit is open or it's closed. If the circuit is closed, you get the same voltage on both sides of the breaker. The circuit should close when you fully cycle the switch arm (all the way off to all the way on).

If the breakers all trip when you try to reset them, you have a bunch of shorts in your wiring.

A better guess is that maybe the measurements aren't quite right:

1) Power should come into the top of the main breaker (when closed)
2) Power should come out of the back of the main breaker to the bus bar in the panel
3) Power should go from the bus bar in the panel to the back of each breaker
4) Power should come out of the screw down lug on each breaker (when closed)

Reference for all of this is the neutral bar in the panel. Neutral should read zero volts relative to ground. All "power" leads should be about 120V to neutral.

One note - at least on my trailer, the 12V breakers are the ones with the green lights associated with them. The 120V breakers look just like the ones in my basement at home ....

2018 Manual:

The 19' 110V wiring diagram is on page 8-18

Breaker panel is on page 8-34

Hopefully somewhere it all that there's enough to get you going.


Lots of fun !!!

I don't believe ALL of the breakers are bad. Unless the coach was in a flood.
Where are you measuring the voltage?
Sounds more like an open neutral problem.
Check the voltage between the hot leg and ground.
Then check it between the hot leg and neutral.
Are you using a meter or one of the test probe devices?
