Oh, forgot your problem. Those original WE 400D KTU cards were almost made to mil spec. They weren't fiberglass PC boards as we know them and probably could be submerged and still work. I have never seen anything that would leak or even any exposed copper that could corrode, though I have seen the gold plated edge connector pins turn green. Has to be from something external but I would be interested in seeing a picture.

Your friend has corrison issues like justbill stated ! Find the source , remove the power from the ksu , go to an eletronics store buy some spray on contact cleaner and cross your fingers . It may take serval cans an applications .By the way what is MSDS ? :shrug:

its a report for hazard on chemicals


Material Safety Data Sheet :thumb:

Heres the pic

Thanks wrichey . Where is the green goo ? and why are some of the fuses blown ? It can't be a working right system ! :shrug:

I see a little something on the far right card, almost out of the pic. That's definitely corrosion.

The green "Goo" is dripping from the far left of the bar code sticker on the bottom of the shelf, in between the 5th. and 6th. top fuses I think. And directly above the top 3rd. fuse if my Wal-mart specs are seing things the right way.

Maybe there is or was a power supply mounted above this equipment that had batteries or just a leaking power supply.
It did not have to be directly above the equipment either, the fluid could drip down onto and flow down the jumper wires and onto the equipment below.

Let us know what you find out if you do please.

I see a little on the m1/25 but none on the cards . Maybe I need stronger reading glasses ! :shrug: . my guess is a leaky sewer pipe or fire sprinkler pipe . Gotta be coming from overhead!

See what you're talking about TexasTechnician. Hard to say by pic. I don't remember what the dielectric was in the capacitors, but I'm sure it wasn't an oil. I really don't think he needs to call in the EPA or anyone..uuuh maybe call a tech?
