There is room for a switch on the opposite side to the shunt. There may even be room for a small regulator. Note I have go a very large regulator so I may need help from other forum members.

Gives "plug-in & play" an all new meaning!

What kind of resistance would there be using that model?

I assume she's wired for DC and properly oriented.
