My 97 4.0l xlt shows too much corrosion on the negative terminal. So much so that it has eaten through the stock clamp.
I have replaced the clamp with a standard type made of lead and now after just 3 weeks the connection of the old ground strap has failed due to too much corrosion.
The terminal connection is now fine showing no corrosion but where the copper wire meets the new lead terminal has now corroded badly and quickly.
I have never seen this problem on any of my previous cars.
Ok maybe a little corrosion after a year or 2 but not 2 or 3 weeks.
Truck seems to start and run fine even if I don't drive it for a few days.
Everything electrical works just fine as far as I can tell.
The only things that have been added are the daytime running lights ( I'm in Canada), and I added a special plug and adapter to run my boat trailer lights which work fine.
Although I haven't metered anything, the battery does spark quite a bit when I connect the terminal even with everything turned off and no key in the ignition.
Any ideas as to why there is so much corrosion?
