12, if you mean 12.0 is a mostly DISCHARGED battery.

Which battery bank read 12?

Are you plugged into shore power?

We've check the voltage on the batteries. They were reading 12 - 13 volts.
tested all the 12 volt fuses, in the bathroom & basement bin, all test good.
Will do the resetting of the Vansco this am. We keep looking for the problem.
Thanks to all for the suggestions.

No 12 volt

SRX Coach, if you have a digital volt meter please use it. As mentioned above 12.0 is a low voltage, while 13.0 is in the proper range.

OK--we have gone 18 msgs now and the conversation is bouncing all over the place. We need to start at the beginning: 1] a fully charged battery measures between 12.6 to 12.8 [at rest]; 2] a battery at 50% mesaures 12.0-12.2 so a momentary measure of 12 or 13 volts doesnt mean much; 3] other than controlling battery charging parameters, the Vansco doesnt impact on your light issue--see below; and 4] the 12v lights on your dash are on the chassis batteries, the rest of your 12v lights are on the house bats--two separate banks, so resetting Vansco probably wont help here.

First--sometimes the simplest thing is the cause--double check the main house cut-off switches in the bat compartment and the switch in the coach door entry way to ensure they are on.

"Assuming" you have 12.0 or more volts in your bats [both banks], your lights should work. Start at the house bats and do a point by point check with a volt meter, if bats are 12v or above, then check the large 300amp fuse in the electrical box above the batteries on the back wall of the bat compartment. If 12v, then check the posts on the house battery main shut off switches [in the battery compartment] [both posts]. If you have a house battery cut-off in the entry way of the coach, check both posts on the switch. If entry switch has power on both posts, then check the feed post on the main 12v fuse panel in the bathroom cabinet under sink. If one of these key points dont shows 12v; you then know the problem is somewhere between, perhaps a connection.

If your house bats are not recharging when on shore power, then the charge function on your inverter may not be working. If the chassis bats are not charging while on shore power, then the Vansco and the battery charge solenoid circuit are not working.

Bottomline--you need to help us help you diagnose what is going on by using the step by step tracing process described above--keep us post on what you find out.

I just repaired a 2005 alpine with battery charging issue. Thought it was the charging side if the xrantrax inverter. Discovered the 300 amp fuse in the battery comp was bad. It's located under the curved plastic cover on the back wall of battery comp. usually best price is Amazon. About 35.00. If you go to rv store they want 80 to 120 dollars. West marine is about 40. Check voltage going into and out of fuse. This one powers 12 volt controlled by inverter

Ref my post #19--sorry if I overwhelmed you but I wanted to make sure you had a working baseline for how the 12v positive side of the Alpine is wired. Perhaps the short cut on the positive side is simply to test the main 12v fuse block under the bathroom sink. The will tell you if all the upstreams control points [see post 19] are working.

If you have 12v power at the main 12v fuse block in the bathroom cabinet, I would then begin to suspect a bad connections on the negative side. My 03 has both a 300amp negative fuse and a 300 amp postive fuse. In addition, most, if not all of the 12v house circuits have negative wires collected in a block near the inverter area--wiring configs vary by model year. Given that you experienced a dimming issue for the month prior to complete failure--a loose/faulty ground connection could explain why many/all of the lights were dimming. Again, this is all based on the premise that your house batteries are and continue to remain charged.

Converter not converting (120 volts AC to 12 volts DC) or inverter's charger module not charging (same thing) and batteries are dead... Might be a blown fuse (converter reverse polarity fuse) or failed breaker if the installers used breakers for that).

But the symptoms (light get dimmer and dimmer and dimmer and fail) indicates the batteries are running down down down and the converter is not re-charging them.

The charge function in the inverter could be turned off!

Thanks for all the helpful messages.
We will leave it for now, as going to be away for Christmas & New Years.
So will look at things when we get back.

Merry Christmas & Happy New Year to you all.

12 volt

Managed to fix our 12 volt problem, it was a loose connection in the last
compartment. At the back side of the In Store Switches. (House Parallel Emerg
Engine) Fuse Block. Next to the Small Air Compressor.

Plus also the Xantrex RS2000 does not seem to be working properly.
Reset has no effect. Constant Fan on back does not appear to be operating.
Charges in Float Mode only.

So have emailed Xantrex to see what advice they can give us.

Thanks to all for the helpful suggestions. Much appreciated.

Verna

We finally got the 12 volt problem fixed, it was a loose connection on the back side of
the In Store Switches. By the small air compressor in the last compartment.
Seems like the Inverter/Charger may not be working properly also.
Reset button has no effect, does not Reboot system. Charger button does not turn charger
on or off. Constant Fan on back does not appear to be operating. Charges in Float mode only. Have emailed Xantrex is get their opinion.
So will wait & see. Thanks Verna SRX Coach

Do you have a System Control Panel (XSCP), if so have you tried to reset the RS2000 from it?

As you have come to realize--the RS2000 is a piece of ___! The constant fan is hard to detect if running and appears to be for environmental control of air in the unit vs temp control by the larger fan while operating. With the menu is global options [expanded] you can drill down the main menu to view device info, then open and drill to last option that set/resets factory options, it will ask you if you are sure--this will reset all options and force the inverter to bulk--like rebooting your PC.....PM me if you want to discuss in detail......
