Hardwiring a Power Inverter When I cut the plug off the inverter power wire, that fits in the cig lighter, how do I know which wire is positive and which is negative or does it matter?
I want to hardwire it, maybe to the battery, and permanently mount it somewhere to use with my laptop.
Thanks! <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Re: Hardwiring a Power Inverter Usually one side of the wire will have a white trace on it... That is the potive wire im pretty sure. Or.. check the voltage of your outlet with a digital voltmeter, it will show -12 volts if you have it hooked up wrong or +12 volts if its right.. when you have it right.. follow the center contact through to the wire and there you go... I also want to do the same thing.. Any good prices on a good inverter?

Re: Hardwiring a Power Inverter Thanks for the info. Got one more. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> Is it necessary to add an inline fuse since the inverter chassis already has a replaceable fuse on it?
All the inverters that I've seen are within $5 of each other and look to have similar specs. The 175watt ones run about $30 and the 300watt ones run about $55-60. The only down side is the smaller one only had one receptacle and the bigger one had two.
Those were at Walmart and Crutchfield. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

If you want to do overkill safety measures.. then you could add one.. But its definately not needed...

Re: Hardwiring a Power Inverter fuses protect the wire, not the device, so if your tapping off a non fused power source, you must fuse it, if its a fuses source, i woudl reccomend fusing it, so if you do have a problem, you blow that fuse, not the car circuit, that could power something you need.
