Transfer switch location???

Bought a used 2010 Jamboree Sport 28Y with only 14k on the odometer after having a 2002 Shasta Sprite & decided we needed a little more room. Really like the rig, but am having a generator problem in that it will not switch over to allow the generator to power up the "box". It has worked in the past, but not currently (no pun intended). Shore line works fine. Have read through the other posts & am pretty sure it's the transfer switch, but for the life of me I can not find the bloody thing. Any ideas where the little devil might be hiding? Yes, I have let it run for as long as 5 minutes with no results.
There's a junction box in the compartment where the shore line comes in, but that's just a 30amp female connector. Opened it up just to make sure.
Looked under the master bed where the convertor/fuse/relay panel is to no avail. Got a whole lot of wires in thar though.
Was an Auto tech for 40+ years so I have a little bit of mechanical/electrical ability.
Thanks!

  • I put a transfer switch on my 31K, mainly because of where the electrical bay is located and the access to it.
  • Not that difficult to install a transfer switch. I did. They aren't very expensive.
  • Now that I know, reading through the Jamboree owner's manual I see what they are talking about, although the picture is quite small & the description vague. We bought the unit from a consignment place so I never talked to the previous owner for little things like that. Have had to figure most of it out on my own. When I sold our Shasta I printed out a whole list of items I thought they would need to know along with some hints.
    Yep, made notes in the book in case of a future brain fart. I've found the breaker on the generator itself. Our Shasta must have had a transfer switch because it switched over on its own.
    Thanks again!!

  • It is idiot simple and relatively foolproof. Just remember to plug in the cord EVERY time you stow it in the compartment.

    Also, the circuit breaker on the generator is very difficult to spot, it is mounted down low, just forward and "around the corner" from the start switch on the generator. It is virtually out of sight. It also takes virtually no effort to trip it. A good hard bump in the road will probably be enough to make it flip off.

    I added a bunch of labels made with my Brother label maker, one on the outlet stating it is the generator power outlet, another stating to check the breaker on the generator if the outlet is dead, another on the generator access door stating that a circuit breaker is located inside, another label inside pointing to the breaker, and lastly, one just above it showing which way is off and on, as it takes a keen eye and a bright light to read the slightly raised OFF lettering on the breaker.

    The older I get, the more I tend to label stuff. It may be apparent now, but I might forget next week, and no use making the next guy suffer.

  • Well I be darned!! I NEVER would have guessed that, CharlesinGA. I swear it worked otherwise. The Shasta Sprite didn't have that arrangement. Surprisingly enough, there's NO information in the Jamboree book about that.
    OK, cool. Another crisis averted :-o))
    Thanks!!

  • Third vote for plugging into that 30A female connector. What else would it be for? ;)
    It works the same as plugging into campground power.
  • That "30 amp female connector" you describe IS the generator output. You have to plug your shore power cord into it for the power to get from the genny to the breaker panel inside the house. There is no automatic transfer switch, YOU are the transfer switch. Plug your shore cord into that TT30 receptacle in that box, and you will have power.

  • Didn't have a jamboree but had a C where you had to plug the shore line into the junction box which is where the generator power was fed to. No transfer switch. Had to keep this plugged in while on the road in case I needed generator power to coach.
