<p class="MsoPlainText">Pesky is a nicer term than I had been using. I clamped the charge circuit and watched the amperage come in on final phase of absorb then drop to zero. (Since the voltage stayed at the same 15.6VDC when the amperage dropped off there
was some current but my meter could not read it. That is the pesky part. Everything seems to be behaving as it should be. I will try the splitting of the parallel battery strings and check each string. And as Jay suggested, take a different brand of controller
with me next time. What is frustrating is this should be as simple as things can get and yet it is so perplexing. Keeps me humble.<o:p></o:p></p>
