Hey that’s cool the way you got all the numbers on a chart that was very helpful thanks
1968 Mustang, GT 428. When I turn the car on, temp gauge goes to hot, the after market temp gauge does not register any activity and I have a blinking red warning light under the tach which I do not know what it is indicating. Is it an over heating indicator warning – but now I am confused as it looks like the three warning lights are for Oil, Alt or brake. My after market gauge says car is charging properly
