Axis/Vegas 30a to 50a

I was wondering if anyone has, or thought about changing the 30 amp service to 50 amp on your Axis/Vegas.

Once in a while, I'll read about someone wanting to do that on another forum. Just wondered since some here are so good at projects.

I'm not doing it, but who knows what the future will bring

Thought about it on my prior coach and then asked myself why?

I couldn't convince myself that the lack of need justified the cost so I skipped the project.

To add 50a service you'd have to add a complete 2nd leg of 120V for what? About the only reason to do so would be to add a 2nd A/C unit.

It may be easier simply to upgrade the A/C unit already on the Axis/Vega then add a 2nd one (note that Thor has an option for an upgraded A/C unit listed on the website: upgrade from the standard 13,500 BTU unit to a 15,000 BTU unit).

If you did add a 2nd one: The Axis/Vegas units are so small you could use them for a meat locker!

Sounds like the only reason to upgrade to 50 would be to add a 2nd ac.
Our Vegas cools off just fine with one ac.

I have the 15,000 upgrade and it worked great in over 100 degree temperatures this summer. I agree, no reason for upgrade and you would need to carry a 50 to 30 amp adapter cord for all the sites that do not have 50 amp.

We have the15,000 ac also.
For those that have gone on trips, did you find that you could run the ac, and use the convection oven at the same time?

Our last mh had 50amp, but the one before that had 30. I just can't remember if we had a problem or not

Anyway, we're looking forward to our trip. .

We could run both, but in practice we usually did not on the generator. On 30 amp, the A/C draws 16 amps running. That leaves plenty of power for the convection oven. The problem comes with the A/C load at compressor startup. You can feel the drop with both on. It is only for a couple of seconds, but I try not to do it.

Anyone in Vegas land who can help me? I have 2014 Vegas 24.1. Attempted to install 2 reading lights on either side of the LED light over the couch. Fished feeds to tie into the LED light circuit. No problems. When tying into what I thought was positive, sold white wire, very small spark then no more power. Bath fan and bath light are out, too. Tried all fuses in smart box under drivers seat, all good. Checked fuses in converter panel under fridge, all good. All other circuits in working order. I have wiring schematic, but shows no white wire with black stripe, which I assumed was ground, and solid white wire was power for the LED light. I am at a loss. Where is the fuse for the bathroom overhead light, bath fan, and sofa overhead light?

That fuse should be located in the house 12-volt distribution panel under the frige/closet. It can be hard to spot a blown fuse though.

Don't ask how I know...

When the fuse blew on my fresh water pump, a red led beside the fuse lit up. Not sure if all of them are that way. This was in the converter panel. Sure helps I.D. which one is gone.

I did check all the flat blade fuses in the fuse block on the converter under the fridge. They all appeared fine, not blown. For some reason, when some fuses are removed, or they blow, the red LED lights up on the affected fuse, but some do not light up. Is it possible a fuse could be blown, but not show a burnt filament? Should I just replace all the fuses to find a possible blown fuse? It is just plain stupid that the fuses are not labeled for each circuit. Thanks for any info you all can provide.

If you pull them out, you can see the broken arch connection in a blown fuse. Very easy to tell if they are blown, but pulling them out is a PIA. I would guess you are in the right panel on the converter for the interior lights. Some of mine are labeled on the door. I will be over there tomorrow and will snap a pic if it looks like if may help you.

David,

A blown fuse is usually obvious, but I've seen a few that weren't. Sometimes the gap can be right on the edge of the clear window or it can be really tiny. Both are hard to see. You can check each fuse with a meter if you have one, or you can swap them all out.

I too am pretty sure that you are looking in the right place. If it isn't a fuse then it's possible that there is an issue in the distribution panel or the wiring. A minor defect in either might have given way instead of the fuse. It happens. There is an old saying among electrical engineers, "every fuse is protected by at least one component."

Good luck!

Randy

I had 30 Amp service and 4,000-watt generator. To avoid the start-up current surge you describe while on generator, I normally started the air conditioner first and then set the temperature very low so that compressor would stay on without cycling on and off. After we got done with microwave, hair dryer, etc. I would then adjust thermostat. It just took a little planning and our motorhome never got too cold.

Here is a pic of the fuse panel. Should be close to the same for yours unless you don't have the labels.
Good luck.

Well, I figured out the power problem in my Vegas. I found a fuse that looked perfectly fine, but it was blown. Yesterday the LED on that circuit did not light up, which would indicate a blown fuse. Today, when I was about to start pulling and replacing all the fuses, lo, and behold, the LED was lit for the bathroom lights , bath fan, sofa light circuit that was out. Why it was not lit yesterday, I don't know. But in any event, it is the second fuse from the top in the breaker/fuse box under the fridge. I will now take the time to pull every fuse, label the circuit on the converter door which fuse controls what circuit. How difficult would that be for Thor to label the damn fuses? Thanx to you all who had good suggestions for a solution. I have done RV wiring and adding lights, accessories, etc., for many years, but this is the first time I was stumped. All the fuses looked perfect. I guess the fuses are made in China.
