The fuse on my Nissan Navara car battery keeps blowing

I keep blowing the fuse attached to the positive terminal in my 2014 Nissan Navara ST-X 550. I changed the starter motor, but after three weeks the fuse went again.

This fuse on the battery is there to protect the entire electrical system (and indeed, the car itself) from damage due to a short-circuit. It’s a good idea, particularly in a four-wheel-drive where you might be running a lot of electrical gear such as extra lighting and a fridge.

The problem with this system, though, is that because it protects the whole car, just about any electrical system on the car can cause the fuse to blow.

If the starter motor is the most recent change to the car’s electrical system, then that’s where to start looking for a short-circuit. However, the problem may not have anything to do with the starter motor. An auto electrician should be able to pin-point the problem and fix it without resorting to simply replacing components one at a time.
