Direct DC power to Trailer

I recently found that my power converter from 120 ac to 12 v dc was defective. I purchased a replacement WF-8955MBA and installed it but there is an extra green wire that the original inverter did not have. After installation I find that the inverter works well but the direct DC power does not work. Is it a problem with not installing the converter correctly? Any suggestions would be appreciated.

    I checked my installation of the converter and all was as shown in the installation manual. I then used a multi meter and checked my voltage on the battery and it was charged. I found my problem at the fuse located next to the battery on the travel trailer. Once I replaced the fuse and cleaned all of the connections everything is working well. Thank you for your help it made a difference.

    After reviewing the manual I believe i followed the steps as described but will check again. Thankyou for the help, once i have checked again and also checked the incoming voltage I will let you know how things turned out.

    Is there a link from the Green Wire on your previous post? I am trying to open with no success.

    Should add that the unit you changed out is a converter and not an inverter.
    Have you checked for incoming 120 volts AC to the converter?

    The old model was 7155, I connected the green wire to an empty slot with the ground.

    What make and model was the old converter?
    Where did the "green" wire go on it?
    Is the chassis ground wire?
