Electrical Troubleshooting Tips For Newbies

[TonyBowes]

Thanks ARoamer. There are several cables clearly marked red/black and I am quite aware where these go. However there is a black cable bound with the 2 positive cables. Hence I asked for a photo of someones battery set up (as per fom the dealership) so I can identify where it should go

That one might be for the trailer breakaway switch. Trace it's path to see if it goes there.

It runs under the boards. Truly, a simple PHOTO would be Good

Just FYI, your camper was never sold in North America and there are only a few users here in the forums from AU, none of which I remember having a 21 Swan Outback RV. I doubt anyone here has a 2021 Swan Outback, which is why no one has provided you with a photo.

However, there are many of us here that have seen and understand a lot of Jayco's 12v common wiring setups, so perhaps if you shared a photo with what you have, that may be of value. Otherwise, you could perhaps trace \ follow the cables on yours or perhaps better yet, if your dealer is nearby, they likely could tell you easily enough especially if they have more of the same model on their lot. ~CA

My 2018 Jayco Precept has been connected to shore power in storage. Went over to check on things and now my TV outlet has no power on shore power or generator. It does work when I turn on Inverter. I took off outlet cover to test power on wires and again no power when using shore power or generator. Only works with inverter. All other outlets work. Would a bad breaker allow the outlet to work using inverter? Need help! Thanks!

A "transfer switch" is used to select between inverter and shore/generator power. This switch can be internal to the inverter or external depending on inverter model. I would think that the shore/generator feed to the transfer switch would be on a circuit breaker.

I suggest finding out what inverter you have and seeing if it has a built-in transfer switch or not. Also, a quick test would be to cycle all of your circuit breakers.

If you can locate the inputs to the transfer switch, that would be a good place to measure the voltage. If you have shore/generator power going into the switch but not coming out, the switch would be suspect as being bad provided all connections were good. If there is no input to the switch then you would look upstream at the breakers and wire connections.

The shore power and generator will have their own transfer switch to select between the two. If you get power from both sources to your other outlets then that transfer switch is good. Your actual outlet appears good because you get inverter power to it.

Hope this makes sense.
