Jayco Power Converter Not Working (Location, Wiring, Replace)

The power converter has a simple task. All it does is take your 110-volt power and change it into 12-volt power so you can run lights, etc. It is not a hard job to do but when something goes wrong, you can lose your power, lights, and more.

One source for not getting any power would be that your converter is going bad. You may see flickering lights, the fridge not running, or other signs. Check to make sure the device is not failing on you before searching for other problems.

Jayco Jay Flight Power Converter Not Working


There are many sources for this problem. One would be that you may have tinkered with the interior and wired a part in the wrong way. Many owners do not like to admit to that mistake but it does happen from time to time.

When it does, you either have to rewire the part or replace it with a new one. Then, there is the simple matter of the fuses and the breaker. Make sure they have not blown or tripped. The breaker is the easier fix as if it keeps on tripping, you know there is a short in the system somewhere.

The fuses are also easy to fix and you just remove the broken ones and replace them with new ones. Then make sure you have power coming to the converter and leaving it.

On the one side, your meter should read 110 AC volts approx., and on the other side, it should have an 11 to 13 DC volt reading. If you have no DC volt reading then you have a faulty converter.

Other parts that may go bad on you will be different internal components. But these can be riveted so that handymen cannot fix or toy with them. Next would be the converter fan. If it breaks down, then your converter will overheat and fail to work.

Finally, the temperature and load sensors can go bad on you. Check them out and if they have, they will need to be replaced.

Jayco Converter Location


It is always a game of hide and seek with RV makers. They hide the parts and you have to spend time looking for them. Many people may not realize that they even have a converter as it is very well hidden.

In most cases, you will find the converter under a seat or hidden in a cabinet. But that will depend on the model of your Rv or trailer. For example, one owner thought his was next to the power distribution center. His may have been but that is not for everyone.

Another owner found his on the other side of the back wall of the power center but to get to it, he had to go through the outside storage compartment next to the power center, then look behind a false plywood wall.

For older models, the converter was under the rear bunk on the back wall. You just never know where they will put that device. Make sure to check your owner’s manual to see if there is a parts diagram with all the locations of major parts on it.
