I have a 1997 Chevy Tahoe 4wd. I believe I am chasing what could be a possible ground issue somewhere. The problem is while idling, the volts drop on the gauge and you can actually hear the engine load and unload when it happens. This happens even when the AC is off, so its not the compressor kicking on and off or the known faulty gauge problem. So far we have replaced the Battery cables, two alternators and a battery. Nothing has helped. Does this sound like a ground issue and if so, where are the possible ground wires?
Thanks in advanced.
