  • another inverter problem

    I was trying to put my inverter inside my car. so i used some power wires and I attached one end to the battery. the problem is connecting it to the inverter. First I connected the positive and when I try to connect the negative, sparks start flying everywhere! am i doing something wrong???

    You may be connecting it backwards, or the sparks may just be caused by the surge as the inverter comes on.

    Either way, are you qualified to do this sort of work?

        Disconnect the ground wire from your battery. (Please oh please) use wire that is at least as thick as the wire coming out of the inverter. Run the positive line, putting a fuse within 18" of the battery. If the inverter is inside the car, find a good ground point (I like to use the seat mounting bolt, or the seatbelt mounting bolt). When the inverter is completely connected, reconnect the negative cable to the battery.

          What AVGeek said is good, but one thing should be mentioned. Using the seat belt bolt is generally a bad idea. While it is true that it is a good ground, it is unsafe to use it as such. Those bolts have very specific torque specifications. Most of the time, torqueing the bolt to that spec is enough to crush your ground wire. Therefore, if your wire is not crushed (thereby ruining your ground) your bolt may be too loose and may back off while driving. This would obviously be very bad in a collision. There are many screws and bolts in a car, so it is easy to find something more suitable.
