1) I may simply not understand the system, or there is a problem. My Scamp is a 2011 13ft model. I have just installed a new deep cell battery (from Costco); the battery voltage is now about 14V. With the 120Vac source connected to my Scamp all electric systems operate. But when I disconnect the 125Vac I have no power to the 12V systems, e.g., lights, fan. I checked the fuses and they look OK, What is the likely problem?
2) How can I check that the power converter is operating properly, though I presume that the answer is that, as noted above, all systems operate when 125Vac is connected?
3) When connected to my vehicle the lights on the Scamp do not operate. I have a 2000 Subaru Forester. The lights all worked last time I used it. I presume that I should look for a fuse problem within the Subaru. Agree, or not?
4) I have not traveled with the Scamp for 18 mo. Any suggestions about what I a complete system check should include?
Not sure about the 120 vs 12v issues, but I learned last year my Tacoma has a fuse specifically for trailer lights which had blown. Very frustrating trying to run that down until I found the fuse. Not sure if your Subie is so equipped, but it would be worth a look at the details in your fuse box.
You have three electrical systems on the Scamp 1) 12 vdc to light the DOT required lights,that comes from the tow vehicle, 1) 12 VDC to run the inside lights and fans etc. may come from 3 places and 1) 120 VAC for the Air and converter.
Are you running a 7 pin cord or 4? 4 will not charge the battery. Was it working before you changed the battery? If you have 12 or more volts at the battery the lights should come on if the fuses are good. There is a fuse in the battery box and some have a second just inside the wall.
If it's the inside lights, and your RV battery voltage goes up to 14 when you plug it in I would think the fuses are good. We need more information.
See the lengthier explanation below. The trailer is not connected to the tow vehicle at present. When it is connected it will be connected with a 7-pin cord. The battery voltage level is 14VDC. It would seem that there is a 2nd fuse after the battery and before the fuse panel but I cannot find one. So I cannot yet understand why the inside 12V lamps, for example, do not function.

12V power issue:
I have just installed a new deep cell battery in my 13' Scamp. It is fully charged. The Scamp was bought in 2011 via Wayne.
My problem: There is NO POWER to my 12V units, e.g., various lights.
The trailer at the moment is not connected to the tow vehicle. The fuzes in the fuze panel look good. The fuze on the hot side of the battery looks good.
Please note that my Scamp has a dining nook in front, not a toilet and shower. I read somewhere in the manual that there are 2 fuzes prior to the fuze panel: at the battery and in the line after the battery, though the electrical diagram in the Owners Manual only shows one. I have looked for that 2nd fuze, but in my Scamp configuration I cannot find it for a check. This is because I cannot physically track the wiring from the battery to the 12V fuze panel.
Thus my question, what might be the problem with the 12V circuit? What can I do to check further?
I checked each fuze individually with a meter. All show full continuity.

In case the problem isn't already solved; One way to troubleshoot a problem like this is to check for voltage at each fuse and connection point along an electrical path, with a common (ground) reference for the negative meter lead. For example, batt + to ground is 12V, first fuse is 12V on both sides, but there is 0 V at power panel: Therefore it's an open circuit between the fuse and power panel. Check the negative battery wiring as well, especially if there is 12+ at the battery terminals, but 0V from Batt + to ground.
No experience with Scamp electrical yet, this is just generic electrical troubleshooting. A couple more thoughts, a jumper-cable can be a handy extension for the negative meter lead when grounded metal isn't close by. Connections can be bad, so probe the wire as well as the metal the wire is mated to.
