Voltage monitor for car battery

[Pic_User]

I am still playing with Paint.net to draw the occasional schematic for the forum.
Here is the latest from the circuit committee.
Put a fuse in place of the input resistor. Added the wrap around diode.
I am learning to not put values onto the schematic. Then people can discuss different values and the schematic does not change.

The entire drawing was drawn in the paint.net (freeware) program, anyone have a better way to go?
