Can anyone make sense of this..
Mercathode System Testing
If your boat is equipped with a Mercathode system, there is a simple way to test if the system is operating properly. The goal is to check the output from the Mercathode controller. When the boat is in the water, disconnect the orange wire that comes from the anode at the mercathode controller. Set the digital reader to show milliamps. Connect the black meter lead to the terminal on the controller. Connect the red meter lead to the end of orange wire. If using the blue or black Mercathode controller, the reading should be 25 or less milliamps, to as much as 200 milliamps in saltwater areas. If using the red Mercathode controller, the readings should be less than 25 milliamps in fresh water areas to as high as 400 milliamps in saltwater areas.
So when it says connect the black tester probe to the terminal does this mean to the negative terminal? and just touch the red tester probe to the orange wire you removed to see a reading?
Also it says you have to do this in water,is there a way I can test while its just sitting on the trailer?
