Remove all loads and charge those batteries up. Then see if they drop on their own from internal discharge.  Could be defective, might as well rule that out.

Subject: Aux battery hookup

Still working on my 88 GL w/ manual tranny. I have run an aux battery for several years when camping. I decided to convert the system using GOWESTY's aux. battery hookup system and 3 Universal UB12220- 22amp deep cycle wheelchair batteries. I did all the wiring as per instructions. Added the new Truckfridge refrigerator, GOWESTY solar panel etc. all power to the fridge, solar panel setup are not connected yet. The problem that is happening is the batteries are being depleted of power continuously. The first 24 hrs it dropped from 12.9 to 11.9 amps. Something is draining it . I thought I read in the archives about the possibility of one of the batteries being bad. Any thoughts hope to get out of here before haying season starts.😗
