Figured I'd chime in with my experience.
My inverter is only on when I need AC power and the rare occasion I plug into 15 amp shore power. I monitor the house battery charging while driving with the Mira app and do not have the inverter on. There is a separate component that charges the house battery with the 48 volt alternator; i do not remember the component name at the moment but that info is in the manuals

Service dept. got back to me and said that things are working properly.
1. bathroom light only comes on manually at the light switch and not through the firefly touchscreen.
2. The battery monitor system in the cabinet
Does not communicate with the firefly touchscreen.
3. The alternator is charging the battery.
My question is can anyone here confirm this is correct?
On the terrain owners manual. It shows the bath light as well as the renogy battery system on the firefly touchscreen.
I also ran the van for over an hour above 1500. Free way speed and have yet to see the BMS screen in the cabinet and dc app home screen showing alternator charging.
Battery charge does not go up unless I shore charge it.
Am I missing something?
Firefly tech emailed me that it should be and renogy tech said that the battery should be charging.
Jayco tech support didnít reply as of yet.
I hope the dealership tech did make parameter adjustments to get it fixed and just not saying it was just a program issue.
Iíll see for myself when I pick it up.

Got it back from the dealer. Back to square 1.
Their answers.
1. Bathroom light cannot be controlled by the touchscreen and only can be done manually. Disabled light option in setting.
2. BMS and touchscreen is known to have comm issues.
Also disabled on setting.
Anyone else here has these options disabled?
3. They said that the alternator does charge and the BMS showed -1.8 amps. I told them that was the fridge drawing that and that not an indicator of an alternator charge. Alternator still wasn’t charging.
Then we opened it up together and found the regulator blinking green. Manual says it should be orange (comm w/BMS)
I ended up taking the van home and the dealer said that they will get in contact with Dehco and get back to me.
Any pointers or advise will help.
Does anyone know of any shops in the Socal area that might be able to help?

Are you sure all your settings are correct including the Rover Boost? Please verify you have checked al the inverter and Rover Boost settings as I do not see anywhere that this has been done by you. Is there a particular reason you are not using the Mira app? Do you have a smartphone? The alternator will show charging on the Mira app, the alternator will charge over 100 amps at freeway speeds. If the app doesn't show it charging, you can show the dealer it is not charging on the app while driving. I also attached a picture of the LED Status/Advisory Codes for the APS-500 Alternator Regulator that I put in this post previously. Where are you looking at the Regulator? It can only be seen with the large panel removed that has several screws. If you are looking on the right hand side at the component mounted on plywood, through the small panel that has 2 fasteners holding it on where you access the solar disconnect and inverter, you are looking at the Rover Boost. Again, I suggest you read this entire post carefully.

Additional issues

Sorry for the delay in responses but I went camping and didn't have reliable internet and dropped out of loop. Anyway, after more experimentation in the field, literally, contrary to my previous observations I noticed that in full sunshine the line from the solar panels to inverter and battery would intermittently fill in (indicating that panels were actually doing something), but I would only get 1 amp. (Incidentally, it would do this whether inverter was turned on or off at switch, which makes me wonder what switch is for.) However, the voltage would quickly shoot up to 70-80V and it appeared that as soon as it hit 80 the panels would disengage and solar power was lost. Which means that I'm not even consistently getting 1 amp! I've contacted Dehco and taken vehicle back to dealer but I'm so confused right now i'm not much help in problem solving. Meanwhile, while camping we sprang two leaks; one directly over our bed, which soaked our bedding and another in electric window behind driver's seat. The first turned on one of the lights in the bump, and above inverter and battery. It would not go off without disconnecting battery switch. I will spare everyone the details and drama of calling RV complete at 2 in the morning (don't bother) and losing a week, and counting, of camping with friends but I'm wondering if water has caused electrical problems. We took vehicle back to dealer with about a dozen issues; including non functioning fridge, webbing pulling out screws, multiple leaks, wheel shimmy (which they say they don't address), squeaky bed lift, etc. So it's sitting in the shop while our friends in new Pleasure Way Rekon go camping.

No luck. These guys are just as confused as I am.
I am now working with Dehco to help me getting it fixed.

Jayco and the dealer were less than helpful. At some point Ill have to have Jayco run a new wire, but for now my unit works and I can go on my montana trip and bondock as planned.
Hi,
I have similar issues. Everything charges except the alternator.
What wire was actually missing and where was the termination point?
I want to check to see if itís the same problem.
Thanks

Swift Li over here with very similar issues, I have to say this thread has been helpful but the alternator charging in my system certainly does have a fault. My alt reg system flashes a code 43, which was not on any paperwork but when I called I was told it is a "no/low voltage sensed at alt + location (check for blown fuse)" you guys know where this fuse might be? alternator charging is what sold me on the unit so hopefully, an easy fix and just need to find the right fuse. I hope I can do a full and proper walk-through video at some point for some future owners.
