Reply to "false readings on Temp and Oil guages"

My car also was experiencing this since I got it 8 years ago. Over the years I'd read a post by someone who said to add a second heavier ground to the black ground wire that feeds all the grounds of the guages & their lights. Recently I finally got around to doing this. I spliced into the black ground wire in the bundle that feeds the guages & spliced in a heavier (16 or 14 ga.-don't remember) wire into it & ran it over to the steering wheel mounting bracket. Drilled a hole for a sheet metal screw in the left hand support & wire wheeled the paint off around it to get a good ground. Crimped & soldered an appropiate ring terminal on my wire & put it all together. Seems to have cured my problem of higher reading gauges when my lights were turnd on! FWIW.
