# 1 check your battery connections. 99 percent of the problems we see when an issue occurs after a battery change is the battery wires are hooked up backward.

Follow the negative wires from the battery terminal. They are most likely white and should go to a bolt on the frame. If there is a fuse on the wire it is a positive wire (usually black or red)

I agree. The signal in the post is the phrase "we bought a new battery for the trailer." I also will bet that the battery cables were attached backward.

It's a bit of a shot to our ego but I've learned to always check the last thing I touched before doing anything else.
If you did connect backwards, your converters reverse polarity fuses will be blown too.

Very good. It seems a LOT of complaints occur AFTER the RV'er has changed the batteries. So, as you stated, go back to what you last did and check the battery connections. Also, IF it turns out the batteries ARE connected correctly, disconnect 12 volt power to the refer or just disconnect the battery negative cable and make sure the unit is NOT plugged into 120 shore power for 30 minutes. That may reset the Refer control logic and it will start working.Doug

Yep, whoever decided that trailer wiring should be Black Positive, White negative needed to get a good noogie!

Everybody knows that Red is Pos, Black is Neg for DC! :D

FOR AUTOMOBILES!.. Winnebago for 60 years has made GREEN negative and BLACK positive. White and Green is RV industry standard for Negative battery connections. 40 years ago Winnebago had the bright idea of installing Diehard batteries for Coach batteries. The reason was, back then there were thousands of Sears Auto centers that could warranty defective batteries. It lasted about 2 to 3 years. Sears part changers would connect the positive BLACK cable to the new battery Negative and the GREEN Negative to the Positive of the replaced batteries. After scores of burnt up Winne DC wiring, (which Sears had to pay for) Sears sent out a bulletin to its service centers that they would only pull and install batteries AFTER they were disconnected by the customer. Customers were responsible for reconnecting all cables. Doug
