Charge battery while still in car?

I don’t know if I ever thanked your for posTing here to try and help me, especially the multi-paragraph explanation about doing the draw test. So, THANK you!

One poster here came up w/ a clever idea of using an infra-red thermometer gadget to isolate which circuit is the cause of the draw… Apparently you point it at each fuse and measure its temperature. The one with the highest fuse temperature is the first circuit to suspect.
