Cathodic Rust Protection ("Electronic Antirust")

[Falken]

Hey guys I am looking for some info on this stuff. I'm not sure but I think it is CounterAct antirust he has installed on his car from the dealer.

My brother in law has a 2011 Honda Civic with this module installed on the car from the dealer and his battery sometimes goes flat after a few days and I suspect it is the cause.

First, is this tech viable on a car? I don't really believe it works for cars.

If it does, great! I'll get one and install it as we have a ton of salt up here.

I dug around and it adds 50mA to the parasitic draw on the car. He has 24/7 security he said (whatever that means on a Honda) and distance starting.

When I add all this up I believe, in the cold, it is too much parasitic drain on the battery.

I'd love to check the parasitic draw on his car but he lives in Laval.

If it works to keep rust off his car I can only recommend he carries a booster with him in the trunk so he doesn't get stranded, as I, myself would suffer along with this system myself if it actually works.

If it is bogus I can tell him to get the unit pulled off or do it for him if I can get a chance to figure out what this thing is in the first place!!

Thanks a lot guys!

Edit: I would also like to know if a battery dying on a 2011 Honda Civic is a common problem from an electronic subsystem or something. This is a real problem and I just don't have the time to diagnose his car by pulling fuses and watching a multimeter if there is a known issue with his car. I worry about him because he works long hours and I don't want him to get stranded!!

according to This Site its pretty much automotive snake oil. caveat emptor(Latin for "buyer beware").

It doesn't work. For rust control in Canada you have Krown or RustCheck.

There are some similar systems on alloy hull boats, so if you drive off a cliff it could help prevent corrosion. If the dealer was any good he would sell you a pressure washer to clean underneath!
I saw one of my friends who is one expert auto inspector in a car wash recently, he drove in and washed the wheel arches and underneath, then drove out again. I asked him why he never washed the topsides and he said it was a waste of money and brushing it damages the wax coating.

I am so glad I wasnt the only one!!!!

I think they use something like this on bridges, so the theory is good. As to it being a good and cost effective system for a recent Honda is another question.

They use it on bridges, boats, tanks, both above ground and underground, so it works...

On bridges, and tanks, and boats.

Not on cars.

Those items mentioned before develop a potential, due to having contact with an electolyte, dissimilar metals somewhere in the system, and a return circuit for the electorns to flow, and create ions the make the metal dissapear/rust.

A car sits on rubber tyres, and is thus not grounded anywhere, nor does it have an electrolyte connecting it to anywhere, so an impressed voltage/current system can't prevent corrosion by reversing the polarity of a process.

Bless you my son.
