I was wondering if anyone else is having trouble with excessive corrosion of wiring in enviroments where the government or municipal agenceys are using a brine solution on the roads for ice control.Here in Newfoundland it seems that this year everyone is having trouble with wiring since the government started using this brine solution.For example a brand new battery cable will rot completely off in about less than a month's use.Any trouble like this anywhere else in Canada or the U.S.?

I think we need to know what it is you mean by "brine solution"?



Is this the relatively new liquid chemicals sander trucks are spraying into the sand or chips as it comes off the truck, or it is the liquid, and liquid only, that is used immediately 'before' a snow or sleet storm is expected?



I know that most road maintenance people have stopped using salt, in favor of using the cheaper but much more corrosive potash. This usually has a pink tinge to it when applied to the streets.

wow only after a month the cable corroded thats some toxic stuff there, has their been excessive corrosion on all the wiring exposed to mother nature. we use ngk anti corrosion grease on our connections and plugs here in ny. Seems to cut back alot of corrosion.

Isn't brine a salt related product? In BC we're using 3/4 minus windshield gravel/sand on the highways and the liquid chemical (municipal) that Jimo mentioned.



There hasn't been any fast action on the wiring that you're talking about out here in BC. I would think some action should be taken to look into what ingedients they're using, there's no telling what else this stuff is doing to other systems and the environment. :ohmy:

The trucking company I worked for began spraying all connections battery and wiring as well as any openings with KL73 by Krown. It seemed to make a huge difference, it penetrates and expels water stopping the brine from getting in. But yes the stuff is a corrosion nightmare.

You'll have to be a little more specific than “brine”. Brine infers salt. Salt is sodium chloride and been around forever it's bad enough. More recently many localities have been using potassium chloride and its really heinous. It will get under your brake shoes and rust so bad it forces the friction material off of the table. There oughta' be a law....

Yeah I've been unable to get online for a while the 15 year old teenager managed to fill the computer with virus's.The trucks here use a 100% salt mix on the TransCanada highway and the secondary routes use a 60/40 or 70/30 mix of sand and salt,this has been the norm for years.This past year the government has started to use a pre-wet along with the old system.The pre-wet is as I said a brine solution,it is salt water and it is constantly moving as not to freeze until it goes on the truck.The idea is to pre-wet the pavement so when the salt comes out of the chute and the spinner flicks it out it dosen't bounce right off the pavement at 60 kms per hour,that's usually what speed the trucks go on the TCH.I think it must be working good because it seems that all the salt is rotting all the power wires off here!

I have the same problem in Alberta. The stuff gets into everything. I have found, if you spray things down with Fluid Film it seems to help.

I just satarted using fluid film and I really like it, seems like a good product. Di-electric silicone is still the best in my books for protecting electrical cables and connectors.



You should try to install that heavy duty shrink tube on the battery cables, the one with the glue inside, that stuff seals 100% of the exposed copper.







The link above is the place I get mine, thay are located in mississauga ON but you might be able to orger it out there.

i use a spray by crc it is a sealer. Any wiring I do i use the heat shrink with the glue inside. Rule of thumb if you think it is water tight put anothe piece of shrink on then you know. I use die electric grease on every wire plug conection. you can never do enough. Solder every connection! i recently rebuilt a 1958 link belt crane from building the tracks up building all the shafts to cutting every wire out and re wiring it along with putting in 2 wabasto heaters. every connection solderd heat shrunk.

I agree with you guys on the dielectric grease and heat shrink tubing. Our shop use heat shrink butt connectors as well. We have brand new buses that still come with main electrical connections exposed to the environment (besides the typical starter wiring) it's become a regular part of our PM program to service and seal all electrical connections including grounds.

That is one thing i will never understand why the factory does not do a better job with protecting the wiring. When i have to put a new female blade conector on i completly cover it with heat shrink then fill it with grease.
