Resolved Passenger Seat Died

[ARD]

None of the functions work on my passenger seat. @NWIP helped me to look in the power bay, but we couldn't find the fuse in there. I looked under the seat, but cannot find where it would be. Battery disconnect has not resuscitated the seat. Anybody have any idea where the fuse is located? Thanks...as always for any help.

My suggestion would be disconnect/reconnect any of the connections underneath the seat. Also check for any disconnected or broken (aka chewed) wires. Does everything work fine on the driver's seat? I would imagine they would be on the same power source. Any wires that are crimp connected should also be verified.

P.S. You or @NWIP need a towbar on the front of your coaches. You must travel together, everywhere! May as well tow one another.

I recall seeing the driver's seat fuse in the chassis electrical bay (first bay drivers side). I would expect the passenger seat fuse to be there too. I just looked at my picture of the KIB board there and didn't see it, so I would look at the Spartan fuses that are in the black box below the KIB board. I believe there are two thumb screws to remove the cover. My picture of that board doesn't show any labels, so I suspect its on the back of the cover which I did't take a picture of. I would run out there now, but its raining.

Posting so anyone reading will know location F20/CB 25a located front electrical bay drivers side.

Oh good idea. Going to check now.

Thank goodness you are coming over. I don't know what that means.?

Look in the bay under the driver's seat (forward driver's side bay) for any lights on under fuses.

Here is a picture of the back of the cover showing the passenger seat fuse. I only got a little wet from the rain.

Updated with picture of fuse too. Not a standard fuse.

If the fuse turns out OK, then I would do what Neal suggested. The passenger seat on mine will stop working from time-to-time and it's generally because the power plug has worked itself loose.

Thank YOU!!!!

Thanks everyone!!! Specially trained recent graduate of the Spartan Academy came to help, but now I KNOW what to do and where to look. This trip is the first time I've actually had a passenger, so will check wires and make sure we are careful rotating the chair. Fuse was definitely blown. Thanks again. ?

Not a standard fuse.

Can we get a little more information on this aspect? Is this non-standard fuse easily available at auto parts stores, or is it a Newmar Parts item? And, is it something to add to the spares box?

Here is a picture of the fuse ... actually circuit breaker. This is a "Type 1 Automatic Reset" circuit breaker.

Here's a link to it on Amazon.

According to the catalog ...

Circuit breaker automatically resets after opening. If the fault still exists, the
breaker will continue to cycle between ON and OFF positions until the
overload is corrected. These devices are sometimes called "cycling
breakers." Type I/Automatic Reset circuit breakers do not address, or
correct, overcurrent or fault conditions. They only react by cycling OFF and
ON. Any overcurrent or fault condition that causes any Type I circuit breaker
to operate should be corrected as soon as possible. Continual vehicle
operation under an overcurrent or fault condition (causing the Type I circuit
breaker to cycle) is NOT recommended.

So I wonder if the circuit break is bad, or of there's a short that still needs to be resolved.

Excellent question. There is ALWAYS a reason why a fuse of circuit breaker opens. Only very rarely is it a simple failure of the fuse/circuit breaker. Usually, it is some kind of electrical short circuit. Sometimes, the cause is obvious and at other times, it is not. Intermittent issues are the hardest to diagnose.

My experience with rotating the driver/passenger seats is that it is all-too-easy to (a) rotate in the wrong direction and stress the pigtail and (b) get the pigtail pinched somewhere. Either situation can create a possible electrical problem. As a result, we rarely rotate our seats and, when we do, it is done with the utmost care.

Looks like a typical auto-reset circuit breaker. I bought one at NAPA. Interesting that the cover indicates that breaker-1 is 30A but the device that's installed is 25A.

If the breaker is operational it should reset itself after a few minutes, if they don't reset then it would be time to replace.

It's also interesting to me that circuit breakers are being used in the seat circuit. My 2015 Ventana has 30A fuses and I've had them blow from time to time so the circuit breaker route seems like an improvement.

Or there is a short.

The cover indicates 25A.

@Neal True If there is a short replacing the circuit breaker won't fix that. I would expect the new circuit breaker to mimic the old. You could insert a 25A fuse where the circuit breaker is. If there is a short the fuse will blow right away. If it's an intermittent issue then the fuse won't tell you anything about that. In my case I think keeping the seat adjustment functions depressed when at the stop was blowing the fuse, for example holding the foot rest button down after the footrest had fully retracted.

 

[Just George]

The cover indicates 25A.

@flyboy013 Yes the cover for the seat circuit breakers indicates 25A. My observation was regarding the cover for Breaker-1 vs the device that is installed.

I just needed a mini 25 amp and that took care of the problem. Picked up a mini fuse assortment at Advanced Auto Parts. And I'm wondering if the fuse blew because we may have forgotten to turn off the seat warmer in addition to the chair being turned in ways it has never experienced before. ?
