Ok. Idk how I ended up in this site but I was researching spy gps trackers because my car all of a sudden wouldn’t start. Well I was looking at the fuses and there that thing is. Big ad Dallas. Idk if it came with care or what?? What I want to know is if I take the fuse out will it stop working. It is a GL 300 MA with a small fuse at one end the other has a black square box. If someone would let me know ASAP I sure would thank you much.
