I have a new 303 RLS and have blown two 30 amp fuses when raising and lowering the front landing gear.
Has anyone had this issue and does anyone have any idea's why this is happening?
 
Welcome to the forum!

The only time that I've blow the in-line fuse to the landing gear is when I've inadvertently run the gear up into the mechanical stop of their travel....suppose it would do the same if run into the lower mechanical stop too. Can you provide some more description of the events?

Thanks Dave,

I have hooked the trailer up to my truck two times. The first time I attempted to raise the king pin from the hitch the landing gear stopped working, I found the inline fuse replaced it and landing gear started working again. The second time it happened while hooking up the trailer to the truck, I hooked up the trailer to the truck raised the landing gear and moved the trailer. When I attempted lower the landing gear nothing would work, I checked and the in line fuse was blown again. When I raised the landing gear I raised it until it stopped, is that incorrect and could that cause the inline fuse to blow?

I'm not sure about the first incident that you've described, but the second incident, running the gear up until they hit the mechanical stop will blow the fuse most times. It's best to mark a line on the landing gear to avoid running them into the mechanical stop.

Thanks for the information Dave, maybe I should paint a line on the legs to let me know when to stop raising the landing gear.

Yes Mike, that would be a good idea. I think the 303 has the same rear stabs that we had on our last camper. You can also pop the fuse on them by running them up into stop...I've tested and proven that also! :rolleyes: You may want to find the fuse location for them too, just in case. Our last camper an a fuse in the DC panel for the rear stabs but the 303 may have an in-line fuse close to the switch.

Hey guys, I have the same problem right now! Could you please tell me where the fuse is. I am stuck in Oregon right now and can't unhook. Please help ASAP. Thanks in advance Boomer.
 
If you're asking about the in-line fuse for the front landing gear, it should be above the battery. Just follow the power wire from the drive motor back and you'll find it.

Dave,
I checked for that fuse and can't seem to find it. I have a cover over the wires coming from the battery with a wire bundle coming out, could the fuse be in there? If it is I would have to remove the battery to remove the cover. Does this sound right?
 
Boomer,
The inline fuse is near the battery and is in a red rubber boot/casing. image.jpg
I have attempted to add a photo, hopefully this will help.
 
Out of curiosity, what size fuse do you have for the front gear?

The fuse holders for the front and rear landing gear on our 337 are marked 30A yet contain 20A fuses. Last camper was 30A and I also carry spare 15, 20 and 30A spares.

Hey guys,
Thanks for the help! I found the fuse, it was were I suspected. I found it under the cover of the electrical connection box. It's a real pain together to on my 303. They may have put it there because I added a second 6v battery. I will be moving it to a more convenient place when I get home. Thanks again!!!
 
You may have an intermittent short to ground somewhere in the wiring. It only takes a split second for the fuse to blow with a short. I would recommend tracing the motor wires up to and past the fuse to be sure the wires aren't damaged. I've also seen situations where a motor with an internal short could be intermittent and result in the same problem. Not with our rig, but with electric motors in general. Good luck finding the problem.
 
Locating the fuse for an electric landing gear is one of the first things I do on a new fifth wheel. Dave gave exact answers to this, if you bottom out the gear retracting it you will blow the fuse 100% of the time.
