If the EWP motors are the permanent magnet type motors, they will have a certain RPM that they want to maintain, and they will draw enough current to do that until they burn themselves up. Is this right, Bill D.? Could be that the higher viscosity fluid had the same flow but would be drawing significantly more juice to do it. -- ,|"|"|, Ernest Christley | ----===<{{(oQo)}}>===---- Dyke Delta Builder | o| d |o www.ernest.isa-geek.org |
