Troubleshooting. Liteswich should be a direct plug-in and work - if it doesn't there may be a problem with either a fuse in your camper or with the Liteswich.
Most often if the lights don't come on when using Liteswich we find one of the following fixes the problem:
* If you are able to first thing is to try the Liteswich on another nearby camper if you are camping. If it works on this other camper the issue that needs fixing is almost positively within the camper that it isn't working on.
* Ensure that your camper has a power source - the Liteswich has no power in it, rather it uses the power already in your camper. If your camper is plugged into electricity it will use the inverter to power the lights. If it is not plugged in it will use the battery to power the lights. Many campers require a battery to be hooked up regardless, even when you are plugged into electricity at the campground for this to work.
* Ensure that all fuses and breakers in the power center in your camper are working properly and not blown. If your lights work when plugged into your truck this should not be the problem.
* The most common problem found by far when the switch isn't initially working is that your main fuse coming off of the battery is blown. This will keep the Liteswich from working. If this fuse is blown it also will keep your electric brakes from working in an emergency if your camper becomes separated while towing. This fuse may also keep your electric tongue jack from working when the RV is not plugged in. This is an in-line fuse coming directly off of the battery, possibly to your tongue jack, and then back. Most people don't even know this fuse exists, but it has a very important function in the event of an emergency.
