Sorry... your "I'm working on batteries I just moved back from Japan"
in post 15 above suggested otherwise and I didn't read the whole thread.
Converters may put out enough current to charge a battery over 6-24 hours when plugged in...but NOT have enough current to drive the big electrics/hydraulics of a campers larger 12V needs alone. So....even if you don't have a battery...you need one.
Now...if you would like to check your CONVERTERS output and workings you can take the 12V battery from your car or truck (starting battery is just fine for the test.) Hook it up...then plug in to AC and put a volt meter on the battery terminals
. You should see at LEAST 13.2V... and as much as 14.5 volts. If you do...the converter is working properly. If not...there is your problem...could be a simple fuse or breaker...so go back to the converter output terminals and check voltage there when plugged in. If you don't see more than 13.2 ...check the fuses and also check the AC voltage at the input to make sure the converter is GETTING AC120V...might be an AC circuit breaker. If you DO see more than 13.2V at the converter output but not at the battery..the problem is in the wiring or a fuse/breaker along the wiring. A continuity test on each wire is he first step.
Some campers require BOTH the converter and the battery to be working and you'll know once installing a battery whether your converter is working and if it is necessary because once the battery is in...you can test the jacks/slides.
A CLAMP AC/DC multimeter can show you how many amps your converter puts out to your installed battery....and how many your Tow Vehicle puts out which is good info to have so if you don't have a basic voltmeter already...suggest you get the AC/DC clamp version at about $50 bucks on Amazon.
