Aw, dat’s purdy.

That is sixteen stainless steel 5/16″ bolts, a parting gift yesterday from Weekender Neighbor S. I’ve been renewing Landlady’s battery connections, and complained to him that her batteries are the only ones in the Gulch that routinely turn connector bolts into puddles of foamy brown goo. I don’t know why this happens, and neither does he but I can try these stainless bolts to see if they’ll resist the destructive corrosion. It means doing some work twice, since I’m already done with the top tier, but replacing the bolts is the easy part. Cleaning up the goo and sanding the connections clean is the hard part.

    +1 on considering protective stuff.

    I’ve tried petroleum jelly and also a special anti-corrosion grease. They work on all batteries except Landlady’s.

    Axle grease. The real sticky stuff. Large globs of it will prevent oxidation. When you put it on, make sure to squeeze it into all crevices to drive out air and moisture.

    Without knowing the materials of the frame and bolts I would take a shot (in the dark) and say this may be the issue.

    This is a different problem than the one at the panel rack, MJR. This corrosion is happening at the battery terminals.

    Hey Joel, I said it was a shot in the dark… :^)
