Yes, in the "old days", gauges actually told you the real-time information (coolant temp, voltage, oil temp, oil press) so it made it a little easier to trouble-shoot problems, but apparently no more. I was able to catch a failing fan belt on my 1976 VW Scirocco (in 1978) when I noticed the coolant temperature gauge was running a little bit higher than normal and the voltage gauge was running a little bit lower than normal. My 1972 Porsche 911 gauges all have numbers on them so you knew the actual temperature or pressure. By the 1980's the Porsche gauges had lost their numbers. Now gauges on cars do not even really tell you information. You have to do your own research to be able to do your own trouble-shooting.
