[DeTomaso] ammeter

[Forest Goodhart]

It is not an unregulated system. What happens is that if the load is on the 
battery side of the amp meter then the load shows as a plus current due to the 
alternator feeding back through the meter to the load. It is not harmful but is 
confusing and it makes it hard to tell if you are really charging.

Would a diode on the fan solve this?  I would imagine that subjecting your
electrical system to unregulated voltage would be a bad thing.  Am I wrong?
