Hi;

On my 99 9-3 the battery terminals are always making a foam like
mushroom that is really corrosive.

I had the positive cable replaced once by the dealer, who said that this
was a problem with the 99 9-3s, but now its doing it again, right before
winter.

Any clue what can cause this? If the battery cables get corroded, then
the startup power draw will kill them and the car will not start in the
coldest days of the winter.

Thanks for help and ideas!

Cheers, Ben

Grease the battery terminals thoroughly - that will stop the
electrolytic corrosion. Use whatever grease you have handy, but not
copper or graphite filled grease. I use moly grease for most things.

There are conductive greases specifically designed for this purpose. As
Grunff says, any grease will do ( I've used Vaseline ), but I've since
switched over to Holt's battery grease.
Clean the terminals well ( you can rinse them off with water or a water and
baking soda solution if you want to get fancy), and apply the grease
liberally.

That's what I wanted to do, but I figured it's an "old" way of fixing
the problem.

BTW, is ther a reason for the electrolytic corrosion, given that my VW
Golf doesn't do it?

Cheers again!

Ummm, that would be *non* conductive grease that you wat to use on battery
terminals.

There is some spray stuff you can get that will do the same job and is
somewhat less messy than just goobering grease on. It leaves a tell-tale
red coating on the terminals. Sold everywhere auto parts are.
