Re: That topic about grounding an inverter?
The original question was whether to run a ground cable to the battery from the negative post on an inverter, or just connect to the chassis. I had made a point about possibly unstable connections using the body/ground circuit.
Those pix show what can happen when the ground leg isnt stable. Who can check every chassis ground connection? Leave the chassis ground for running lights and car stereos, hook the high amperage stuff up cable-direct.
