Gentlemen,
Thank you for your responses. Work and a sick Little One have kept me busy since I posted. I have had time to take off the tender shell, and can indeed confirm its a QSI DCRU.
@Vernon Barry, I will work thru your advice on the direction lock out wither tonight or tomorrow. I have the manual, and had followed the directions, or so I thought. I did not think about there being a voltage leak. I feel I will be lucky if this is the fix, based on what @gunrunnerjohn said.
Ill report back after I test. Thanks again!
