hi there, i have a dick smith inverter that ive never used until now but everytime i try to use it it seems to just suck the power out of my car to the point that you plug it in and all the lights start to dim and keep dimming unless i unplug it. The inverter has a positive, negative and ground. The positive and negative wire to a cigarette lighter plug and i was wiring the ground to a screw going into part of the chassis behind the dash. Any suggestions as to what i could be doing wrong!

I would have expected it to have only a positive and negative lead which, as you say, would be wired to a cigarette lighter plug! I don't know why it has a separate ground! Try leaving it off! If it's drawing excessive current, it should blow a fuse! Do you have the problem even when you have nothing connected to the output! Are the wires on the cigarette lighter plug the right way round - the positive should go to the centre pin!

The earth wire is for the 240VAC side of the inverter and should be connected to a decent sized earth stake which is driven into the ground. Given that most of use these in a mobile situation this is not practical and so it is simply left out.
