For these devices to work, anything ferrous that you wish to protect must be kept between 0.85 and 1.1 volts more negative (when measured with a copper/copper sulphate reference cell) than the cathode trying to protect it. The cathode must be able to "impress" a current into the bodywork, brakes etc.
If the vehicle is negative earthed, how are you going to make the rest of it more negative? What medium do you use to impress the current into the metal of the vehicle?
Sorry folks, these devices will not work unless the vehicle is completely emersed in some kind of conductive material like soil or a conductive electrolyte.
Don't waste your money, just wash the vehicle regularly.

Your car isnt going to start rusting the second it sees salt or sand because you have gone for a day trip on the beach.........but leave that salt sitting there for 6 months and its probably a different story!!
Sprinkler under the car ah Blue...........Sydney water would crusify me for that i think.
It probably works best around coastal areas and where there's plenty of exposure to sea water, spray and mist as this would allow the charge applied by the erp to have the greatest effect.
