I had a recent flood - into the battery casing on my umbilical - due to a damaged o ring. The head also flooded, I am assuming it went through the cable. Does this sound right? If so - how do I stop it happening again?
I have toyed with the idea of potting the cable ends - but what with & how to make a secure pot in very little space?
What is best practice (other than keep the o rings good - so it does not flood to start with!)
