Gas should be above Empty, oil should be between approx 30-60psi depending on the revs, Volts should be a little above 12, tach should be at 7k once a day atleast, speedo, as high as you can get it without getting caught, and my temp was always right around the little marking in the middle of the gauge, depends on what your dash style is. What year is your rx7?

it has an 83 motor but possibly a 79 tach bc it's a 79 chassis. there are also 3 gauges in the center console. oil pressure. oil temp and water temp i think. i will check for sure when i get home. the oil pressure is usually 40psi unless i give it a real good rev. and the tach, tickin clock, engine temp and water temp dont work. i will make check all what works and doesnt. thats all i remember right now, im thinkin some wiring issues so i will get my electrical engineer friend over again and have him fix it if it is wiring.

Sounds like there might be some. If you have this dash style, this is the ideal readings.
