12V machine data collection [RE-wrenches]

[Ken Hulet, Engineering Services Co.]

Looking for ideas to collect power used on a small 12VDC agricultural 
machine.

We need to collect some data on a prototype used in the field. I recall 
seeing an HP article about using the HOBO units with current flow 
sensors. Does this make sense for the prototype data collection?

If this all works we'll eventually want to add a user 'fuel gauge' on 
the machine. Do you think the simple volt meter schemes are acceptable? 
This is a LOW power machine, less than 50W.
