Most small trailers will have a 30 amp power cord that you can plug in.

Air conditioners, microwaves, hair driers all need the power source. To use your household type plugs, you will need to be plugged into a 110 power source…ie household plug or a generator. When you are plugged in, the converter box will charge the battery.

When you are not plugged in or using a generator only the 12 volt items will work. The household plugs will only work when you are plugged into an outside power source. Here is the catch….your two systems are separate. The breakers should remain in the on position all the time. These are the protection circuits breakers for when you are plugged in with a power cord. The circuit breakers on the left are like the ones at your house.

If one is “blown”, there should be a red LED light next to the bad fuse. While under battery power, you will be using the colorful car type fuses on the right. The next set of fuses is in the converter box. Stereos, CO2 and smoke detectors can draw from the battery while in storage and cause it to go dead. I also take this fuse out when I store the trailer for an extended period of time to keep the battery from running down. I usually leave it hanging out of the plastic battery box for easy access. The first fuse to check if things are not working is the fuse at the battery….remember the one that is connected to the + terminal. All other wires go to the – terminal.įuses protect the trailer wires and electronics from surges or improperly hooked up batteries. If there is another red wire, connect it to the + terminal also. So basically, find the line with the fuse and connect it to the + terminal. The remaining two white wires will connect to the – terminal. The wire coming from the trailer that has the in line fuse (this time it is a white and black wire) will connect to the + terminal. This red/yellow wire will connect to the + terminal on the battery.Ī-liners and some of the trailers that do not have the solar connector wires will follow the same basic rules.
