Stabilizer Fuse Blowing

[Riley49]

We have a Rockwood Mini-lite. It has power stabilizer jacks. The 30amp fuse for the jacks is blowing instantly regardless of whether we connect to battery or shore power. After reading some other forums, we ran them down manually a bit, but this did not solve the issue. They worked fine last weekend. Anyone have any ideas?

I suppose the trailer has been moved since last weekend.

Has any work been done such as jacking up the trailer, or maybe pinching a wire in the process? Time to do a visual inspection of the wiring. Look for chaffed or pinched wires.

One or two stabilizers? One works, one doesn't work, or neither works? Visually check the back side of the stabilizer switches. Is there anything else that doesn't work?

Just basic troubleshooting by progressive isolation.

It was moved yesterday when we came to this campsite. None of the 4 stabilizers work, two switches all on the same fuse. Change it and blows as soon as you give the trailer power, battery or shore. We are going to try to inspect the wiring today because it got dark on us last night. Everything else works fine and no other fuses are blowing.

Our Rockwood Mini Lite 2511S just started blowing the 30amp DC fuse for the PS2X stabilizers by Lippett. But only while traveling.Has functioned flawlessly for two years. Just started this trip.
I pull the fuse after retracting them before we hit the road.
I did do a hand over hand inspection of all the exposed cables and there were no abnormalities. Have not had the opportunity to trouble shoot the switches and hoping the main splice is not covered by the fiberboard underneath but is behind the DC panel board.

With 12V battery disconnected.
Multimeter set to ohms, full range 10 ohms (smallest scale)
Black lead to ground point.
Using Red lead to fault find now.
Fuse removed. Red probe measure to each side of fuse block clips. Which side has 0 ohms?? This is the bad wire to trace.
Disconnect red wire at linear actuator. Use the red probe on both red wire and actuator connection point. Which side has 0 Ohms?? This is the bad wire to trace.
Continue above test pattern for each connection that you can find.

The ground wire on the actuator shouldn't be a problem (unless this wire has switches/components)(I certainly hope not!!)
Hope this 'rings it out' for you.
(old days they used a bell . . . you could troubleshoot at a distance . . .

Another trick that may help is to attach a light bulb across the blown fuse's two ends.

Put the fuse-and-bulb into the fuse holder. If it lights then it'll blow the fuse too. (light bulb doesn't light it 'may' be ok)
When the light bulb doesn't lite there's no short at that moment.

Same problems. Same year?
