Very disappointed in Jayco's wiring methods

The water heater in my 25RKS has not worked on electric since I bought it earlier this year. So today I decided to do some troubleshooting and see if I could get it to work.

I found no 120v at the element. I checked the wall switch and relay and both were good. I confirmed voltage at the breaker so I started at the heater and worked backward looking for 120v.

I found that Jayco had run solid house type wiring from the breaker box and joined that to stranded wire just before the relay. That joint was made with an ill fitting scotch-lock type automotive connector. Both connections were loose and there were burn marks on the common wiring. See the attached photo.

I think this is not a very safe way make high voltage connections. They should have used an enclosed terminal block of some type.

Definitely should forward those pictures to Jayco along with a detailed description of what you found. Thankfully a fire didn't occur. A recall may be in order if this is the same setup in other models.

Were the wire nuts inside a junction box? My understanding of the building codes that TTs are built to all 120VAC connections have to be in a box, just like in your home (same rules apply). Where the 12VDC is considered a low power source and do not need to be in a box.

The high volt connections were just scotch-lock connectors with tape around them. The house type wire was secured to a drain pipe with a zip tie. In the lower part of this photo you can see the connectors with tape. The only thing in a box was the relay.

Very very very wrong! My guess the fabricator on the job was behind and that is how he got his job done before the unit was pushed off to the next station.

I wonder if others who have this same unit (25RKS) have this same wiring setup? What year is your unit?

If you bought it new I would also recommend contacting Jayco.

I would be interested in knowing if other '07 Jaycos have the water heater wired like this. I do plan to send a note to Jayco with this information.

I wouldn't hold your breath on getting Jayco to even recognize your little electrical issue.

I never heard anything from them about this issue:

Are you certain that the dual heat source water heater is OEM? Was a dual source water heater standard? My 2001 23B is propane only. Maybe a previous owner had the tank replaced?

Just questions. That is some very poor workmanship at any rate. Good job tracking it down. vic
