Dellman,

Voltage measured anywhere in the circuit when the system is charging should be in the neighborhood of 13.8 volts.

If your rig isn't doing this, you need to check all the components of your charging system...generator/alternator and regulator is you have one.

17 volts is enough to kill almost anything on your truck and 10.5 is a warp five discharge. What are you measuring this with...something doesn't make sense.
