Re: Charging LiFePO4 Batteries

My understanding is that lead acid chargers generally can be used without causing damage to LiFePo4 batteries. But as you mention you won’t be able to fully charge the batteries and for optimal charging and care of LiFePo4 batteries they really need that absorption charge. A number of different manufacturers state that lead acid chargers shouldn’t be used and may cause damage. Possibly they are just covering themselves. I think much would depend on the parameters of the Ryobi charger.

Re: extra negative wire crimped to main on battery?

In our 2023, the extra ground wire goes to the plastic junction box for traveling lights and brakes under one side of the trailer's A-frame per @Yoshi_TAB 's comment. There's also a green positive wire that doesn't go to the tub, but exits with the other tub wires down where they penetrate the trailer.

Hmm.... Just when I thought this was going to be easy... lol. I will have to pull the tire and check everything more closely at the junction box. I'll update you whenever I can find time to look at it.

Hi,
Just for my curiosity..double check where the second pigtailed negative in the front box leads to. Doesn’t go to a solar connection? A second battery? Do you have a helper who can assist in running a continuity check on what you think are both ends to confirm the other end. Maybe email Nucamp Tech support?
Good luck..RV wiring is often like the Wild West

Re: extra negative wire crimped to main on battery?

This is peculiar. It's unclear to me why the traveling lights and brakes would need a dedicated ground wire back to the battery. These systems are powered by the tow vehicle via the pigtail and typically do not involve the battery in any way.

Also, at least in previous model years, all connections were made via terminal studs in the junction box. Even if you did for some reason want to connect the traveling lights and brakes to the battery negative, you could do so at the terminal stud in the box without having to run a separate wire back to the battery. The photo below shows the arrangement of wires in the junction box. The labels are on the positive terminal stud, but the same connections apply to the adjacent negative terminal stud.

As noted in earlier comments, running a ground from the Alde directly back to the battery was previously prescribed as a solution to the frequent blowing of the Alde fuses, but that issue was largely rectified with the upgrade to the Alde 3020, which (I think) eliminated the fuse on the Alde's negative power leg. Direct grounding of the Alde cabinet was also kicked around as an early solution to the convector corrosion issue, but I'm not sure if that ever got much traction.

So, I'm left still still wondering exactly what the purpose of that second negative wire is. At first pass I'd have guessed a mod by a previous owner, but this case the T@B was fresh from the factory.

Re: Newbies from Washington state and Oklahoma

@MilesCamp - good question. I have lost the ability to tweak signature lines with a past update. @ScottG - any ideas?

I notice the same thing, and thus far can't find any way to restore moderator access to this feature.

@MilesCamp, did you by chance set up your signature line using the Firefox browser? Vanilla has a long-standing quirk with Firefox where it inserts an extra blank line every time you hit the return key. Sometimes you can fix this by toggling the HTML code and removing the extra command. However, it's generally easier to just open the site in a different browser and make the necessary edits.
