I have a 1983 Juno Real-Lite travel trailer and I would love to have the manual for my Carson Power converter CP20FKCS. The 110v and the 12 volt is working, but I can't get battery power to work and I need the manual to troubleshoot. Also the bottom Buss fuse holder screw in cap is missing (probably part of my problem). Anyone know where I could source one??? No mention of this manual anywhere on the internet and Carson quit making these and no longer offers support!
