A couple days ago i posted how i was getting 12 volts off of my frame and no power to anything. Some lovely folks here helped me to figure out a new ground cable off the battery to the frame fixed the issue. I now have ground and power to everything as well as my truck starts and runs again. However, and maybe im just throwing rocks at a beehive here, but i had a thought to test with a multimeter from the negative battery post to the frame with out the ground battery cable attached. To my surprise i still had a 12 volt reading and when i reattached the cable to the battery i had a 0 volt reading again. So my question is, is the new ground cable just a temporary fix to a bigger problem or is this something that is somewhat normal? From my understanding i always thought the frame was ground with or without the negative cable attached to the battery

Let me use this simple circuit as an example. It consists of a battery and resistor. Let the lines between points 1 and 2, and points 3 and 4 represent wires.
As the circuit is now the wire between 3 and 4 is ground or 0 volts. If we remove that wire so we have an open circuit and measure the voltage at point 3, it will measure 9 volts. This is the same as what you're experiencing. However in your case the resistor can be anything such as a gauge on your instrument panel, radio, sensor, etc. Nothing to worry about.
