I just pulled my trailer out of storage and put on a battery tender -- three days later - it still shows charging -- battery voltage is 12.8 - but I also changed out my power center to a WFCO WF-8735 unit -- have it all hooked up and the 120V side works well -- and when plugged into shore power - Both the 120 and ALL 12 V circuts appear to work -- I get 14+ v at the battery - But when I turn off the 120V - I do not get the battery to work the lights or the water pump -- Is it possible for a Battery to measure Voltage - but when put under laod - to not work??? even with the tender still connected - the Lights or pump do not work
Thanks
Alex
