Hello all, I have a KR200 with KRC1 control. The robot has been sitting a couple of years and I am trying to get it powered back up. I replaced the backup batteries but the controller shuts right off when you throw the breaker instead of staying on and shutting down properly. Also the robot loses mastering every restart. I check the battery connections and am getting 27VDC while the controller is running so it is trying to charge the batteries. Is there anywhere else i can look to check this out further?
Edit: Thought I should add, usually when I change batteries and make the last connection there is a small arc of electricity. When I put the new batteries in this one and hooked them back up there was no arc.
