How do I clean fishfinder contacts?

[mercerfisherman]

Hi. I own an Eagle Magna III Plus fishfinder. It worked great all last summer. This year nothing. I thought I would try and clean the contacts / connections but the holes where the connectors plug in are so small I can't get anything in there to remove any possible corrossion. Should I try spraying some WD-40 in it?... Take a needle or paper clip and work it around. Battery connections seem to work for other units like bilge pump, livewell, etc. Any ideas?

I usually use wd40 for that kinda thing

There is spray stuff which is formulated to clean contacts. It is called "Contact Cleaner" and is available at electronics parts shops. I doubt it will work on "green" connections, but in conjunction with a strait pin you may have some luck
