[QUOTE="me2, post: 342338, member: 3825"] Inverter Wiring Warning One thing to note about inverters is that if you are connecting anything to a computer that connects to the ground on the truck, you have to check that the inverter ground is the same voltage as the truck ground. Take the EFI Live programmer, for example. The programming tool is USB based, which means that it connects to the computer ground. And the programming tool also connects to the CAN Bus connector, which has vehicle ground. So if you have a laptop running via its battery charger from the inverter and you have the EFI Live programmer plugged into the CAN Bus port and connected to the computer, you have connected the inverter ground to the truck chassis ground. Sometimes this works just fine and sometimes it will fry either the laptop or the charger or the programming tool. Or maybe all three ! Before you do something like that, you need to verify that the inverter ground is at the same voltage as the chassis ground, even with a load connected. Some/most inverters tie the AC output ground to the 12VDC input (chassis) ground, but some don't. I haven't looked at the Xantrex 1000 yet, but I have a Xantrex Prosine 2.5 in our trailer and it has a dedicated chassis connection to tie the AC ground to chassis ground. Every inverter is probably a bit different in this regard. The same thing applies to other devices powered by the inverter, such as oscilloscopes and stand alone scan tools. Hope this helps someone.
