Hi I wanted to inquire further about your comment : "With the 7 pin connected to your TaB, isolate the battery (remove your battery fuse), start your TV, then turn on a light in the TaB. If the light comes on, you have a charge line. Turn off your TV. If the light goes out, you have an isolation relay in the TV. If the light stays on, no isolation relay."
I rarely participate in forums so I am not sure how to best respond to peoples individual comments. What is an "isolation relay in the TV"? Thanks
