Sid, Try an anti-corrosive. CorrosionX makes a series of products that address this problem. I use CorrosionX-Aviation for electronics (it's "milspec") and CorrosionX-HD for hardware. http://corrosionx.com/ I have no affiliation with this company, I'm just a fan of their products. I have been using these two types for over 4 years on my '93 BMW 850 which is electronically VERY complex and notorious for intermittants. I have no such problems any more. Their spray bottles are the best deal and last the longest. I usually just dribble a little on a Q-tip or my finger or epoxy brush and wipe onto the part(s). Cheers, Roger Byrd Mount Airy, MD
