I'm installing mercathodes as part of my TRS to bravo changeover.
My boat is a trailer queen and hasn't seen saltwater in 10 years. Therefore I'm not wiring directly to the batteries, but thru the battery switches.
From what I've read ,there is no draw until they are in water, when the reference anode detects stray voltage in the water ,then it sends out a blocking current, right?

They come with a 20 amp fuse, that seems kinda high for something that constantly runs, no?

How much current do the mercathodes draw when the boat is in the water?

Thanks,
DS

i would like to know more about how this system works also as i have it on my cig.

All good questions. I have them too, and I only assume they are connected correctly. This year I will be in the water all season, probably a good idea to be up on this stuff.

I was about to post if anyone knew how to test the system.....
Looks as if we are all in the dark on this
