to much rust behind the pads move them to other rust free areas & they should work fine until the rust reaches them again !
good luck

Why don't you just apply some snake oil underneath and around your vehicle ;)

I recommend you forget the erps.

Buy yourself some lanotec and spray/apply it everywhere possible - and reapply every two years (odd)

No they don't work......
I have already had my Hilux back to repair rust........ Fortuanetly there is 5 years perferation warranty. It is just over 3 years old. I had one fitted before I took delivery of the vehicle.

I think that this site is one of the best.... nah the best site for 4wd, and out bush 'how to' things. It has an air of authority about it and quality.. and then the ad below.. for unproven claims and 'snake oil'. I guess the site needs to have advertizing support, but I also wonder what the advetizer thinks when the product is so roundly condemned by experienced people here??

Dr Karls reply is not based on capacative electronic rust proofing. It is based on sacrificial anode rust protection such as boats amd bridges etc.

ERPS is different. Provided that the vehicle has paint in good condition (very important) then they do work. For 4wds used in highly corrosive environments like beaches etc, then up to 6 pads are placed around the vehicle to ensure full protection. If you get a digital multi meter, you can actually measure voltage across the paint on the vehicle. My last vehile had a dealer fitted snake oil unit with only one pad. Absolute rubbish and would probably only protect next to the unit.

Local councils here in QLD have put ERPS units on their beach vehicles with amazing results in preventing or dramatiaclly slowing donw existing rust progress.

No I don't work for them, no I don't have one but I intend fitting one to my new vehicle before my first beach trip mid year.

Hows it going Mark,

Was going to ask you to explain Capacitive rust protection , but I Googled it and got this from the CouplerTec site , isnt this the same as a sacraficial anode type set up exept the box supplies the electrons ?

Basically, rust is the loss of electrons from within the metal. Oxygen combines with the metal atom and forms FE2o3 Ferric Oxide, that?s rust.

Here we explain Capacitive Coupling in Laymen's Terms.

What we are doing is interfering with the oxidization cycle, in other words, tricking nature.

We achieve this by artificially pumping electrons into the vehicle so our supply of electrons exceeds the demand.

This is achieved by creating a capacitor, our pad that is affixed to the paint acts as the positive plate in the capacitor, the paint becomes the dielectric which in turn holds the charge static (keeps the electrons from flowing away) and the body of the vehicle or structure acts as the negative plate in the capacitor.

So what we are left with is a big capacitor;

- 1. The pad is the positive plate
- 2. The paint is the dielectric
- 3. The body is the negative plate

Electrons are built between the positive plate and the negative plate and the paint keeps them there. How Simple!

Don't know if they work or not, but then that's my concern. Had it fitted when I bought the car and haven't got any complaints. Stones chips (deep enough to expose bare metal), that were on the car when I bought it still show no signs of rust. I live only 8kms from the beach so there's a bit of salt in the air and any metal objects left in the yard get rust on them (seats, bits of angle iron etc). but nothing on the car.
The unit stopped working once and after contacting the installer he advised me that sometimes after washing the motor some water may cause the sensor to temporarily cease working. It fixed itself the next day and since then hasn't been a problem.
