good morning. I have a problem with the victronenergy Cyrix Ct 120. I did a somewhat different installation from the manual. I put a switch on contact 85 start assist to start the engine with the service batteries. In addition I also put a switch on the negative contact 86 of the coil. In this way I disconnect the cyrix to prevent the panels from charging an already charged engine battery every day. but if one day I decide to reconnect the cyrix with the switch on the negative contact, once the cyrix closes with voltage greater than 13.2v, it is always closed ... and does not open with voltage less than 12.8v. To get it to work properly again, I have to operate the "start assist" contact switch and then turn off the "start assist". In this way, the cyrix resumes its automatic functioning. But every time I turn it off from the negative and then reconnect it, it then gets stuck in the closed position. Anyone know why this happens?
