Thanks for the reply Dave,
I was taught to take negative cable off battery. Connect test light clamp to cable then place test light to battery terminal and if bulb lights up then there is a draw or short. Radio will have a little draw but light will be very dim. My light was bright. Pulling the fuse with draw/short will cause the light to go out or dim. This was when I worked on a couple of cars in the 90s. This method is fast but maybe its not good to do on these newer cars. Dont really work on cars anymore but bought this one for my sons first car now having issues. I had the battery tested and it is good. It seems like I might of lost connection between fob and ignition. I can lock doors with fob but it does nothing when i put in the ignition. I cant even put the car in neutral to tow it to the shop
