I have a Stinger 1 farad capacitor on my system in my camaro. On my digital display screen it normally reads anywhere from 13-15 volts which is normal.I noticed, when it is a really cold morning my voltage will read 3-5 volts and will set off my low voltage alarm, which is very annoying, but once it warms up during the day, it goes back to normal. Also when i dont crank my car up for awhile (due to having another vehicle) itll do the same, does anyone know if this is normal or whats wrong???
That is normal, your car will read 12 to 14 volts when the car is at normal idle after you drove around, when the car is cold it takes time to build up. It s like when your battery dies and you get a boost right after the booste you turn your car off and it wont crank, but if you let it run it good to go. Its just a process of the car electrical system building strength.
If cap made that noise while you were driving then you would have a problem.
