I am getting a low battery warning on the controller and have replaced the battery and still the same warning. When I shut the utility power off the controller shuts off. When I power it back up the control comes back on. Any ideas ?

Sounds like maybe a bad 7.5A system fuse. Either that or a bad connection somewhere between the battery and the controller, or there's something wrong with the controller's 12V input...

If the fuse is good, start checking for 12V DC everywhere you're supposed to have it.
