Aloha, I put my pump on my headlight circuit. I know, I know,
I may get flamed for this, but it works perfect. It is a very hi
amp draw pump (boat bilge pump 24L/min @ 20watts) and it
was killing my battery on the regulated side. Now I guess it
barely spins at idle and spins crazy at hi rpm (14-15+ volts).
Seems to work like a charm on the unregulated side. frank.
