2016 PW Lexor TS here. About a year ago. I changed out mine. Actually was pretty straight forward. Just turned off the switch to house battery bank. Disconnected the chassis battery negative pole. Check the separator power connections with multimeter. No voltage. Changed out and replaced with new separator. Used bidirectional. Why? It was the OEM. I guess a unidirectional would work as well. There is a small ground wire on back. When chassis battery is up to 13.4 or higher, the switch is closed. If separator is malfunctioning, the switch stays closed and does not open. When this occurs, separator stays closed and is always warm. House and chassis battery are constantly connected so higher voltage drains to lower batteries. An easy test is just disconnect the ground. This will open the separator circuit and keep batteries separate.
