hi all,
I have a short in my harness as I'm getting voltage when I shouldn't and not enough voltage when I should, it doesn't change. I have a 12v dc system on my boat. I think I have found the fault to be a multi pin connector in the harness. It is greasy in there and i didn't help the cause spraying wd40 thinking it would because the voltage/short increases.
it's a plastic connector, approx 30 pins. My question is how can I clean it safely, remove any corrosion and then protect it.
I'm not sure why its faulty or what's caused it, I can only think as the boat has sat for a number of year and the small amount of water in the bottom has condensed on it. The connecter sits in a bracket on top of the engine, and during warmer times and close proximity to the cold engine and bracket has cause moisture to get in.
according to the wiring diagram, the wire which is causing me a problem is wired direct from the ignition switch to the fuel cut off solenoid. I have disconnected both ends and still get a voltage of 5v, though this changes daily as yesterday it was 7v, disconnecting the connector this disappears and is 0.7v.
I'm 60% sure the connector is the problem, but how is best to clean without poking it so not to damage the pins etc.
I have read about radio ops using vinegar and salt, then neutralised with soda. Would dipping it into a solution of something be my best option and if so, do you recommend something. I'm in the UK, so uk brands only please as we dont get the good stuff over here.
thanks in advance and let me know if you need more info.
