Missing Charge Controller Sticker
Dealers often remove prewired stickers during dealer prep. Thinking they are helping clean up your RV during this time, they actually make it more difficult to find the proper location.
Tips to Find Missing Charge Controller Sticker
I have been able to help customers by searching for the exact model of RV on the Internet and finding units that are listed for sale. Sometimes the pictures of the units have the location of the charge controller sticker memorialized in photos.
Look for the residue left by the sticker. This can sometimes be effective when the adhesive residue has altered the finish of the wall panel in your RV. Several customers have used a flashlight to aid in this attempt.
