Blue Sky Controller and IPN Remote not powered

[fritzfrangle]

2016 Legacy Elite II

 

During our travels I noticed the battery charge controller IPN remote was not powered. Checked the Blue Sky controller and it was not powered either.

 

Troubleshooting revealed a failed terminal crimp at the negative shunt on the negative cable from the Blue Sky Controller to the negative shunt.

 

Inspection determined that the wire had not been stripped enough to bottom in the terminal end and had pulled out.

 

The failure was hidden within the heat shrink tube

 

See attached annotated pictures.

 

Luckily I had a new terminal end to make a repair as we have been on an extended boon docking adventure.

Thanks for posting this, good info for those of us with Blue Sky solar. Mike

Good catch. I’ve been doing some doctoring in that area and ran across a loose crimp that surely would have failed. I’ve also found some wires under tension with no strain relief that were time bombs as well.  And some sharp screw ends with wiring looms up against them.

 

*sigh*

 

I really hope that Oliver is doing a better job with their wiring these days.

That was some great troubleshooting!  Thanks for the write up and pictures.  I agree with Overland, there is a history of wiring issues that a number of us have had.  I hope the factory folks look at this forum and realize that quality of assembly workmanship is something that needs to be managed and maintained.

 

Our trailers are not static devices and can be subjected to vibrations, poor road quality,  impacts, etc. that can cause wiring connections to fail.  My Fluke multimeter and some electrical first aid items are part of my Oliver support kit.

 

Safe travels.

Obviously in the pictures we can see what and where the problem was.  But, how did you ever find it given that it was hidden by the shrink tubing?  Was it as simple as noticing that the wire was loose even though the terminal was tight or did you find it via a multimeter or something else?

Found the issue using a multimeter.

 

 

 

It would really help having a set of wiring schematics for the RV. After we purchased the trailer this past winter I asked OTT several times for a complete set of schematics for the wiring they produce and was never successful in obtaining them.  They replied that all the info is in their manual . It isn't .

 

We did the factory tour and I spent extra time in their electrical production area and assumed their employees were using schematics to produce the coach electrical harness so it should be available.
