I dont know what to think as most Electicals SHOULD have a Protective Coating from Water, (salt water im not that sure about and standing in Water for long time)

The components have, but the circuit boards they sit on don't.
Water, particularly water from a flood, will have impurities in it which can, and generally will, provide a path to a short circuit as soon as they are powered up.
The answer is to remove the electronics completely from the bass and do NOT be tempted to power it up as this will definitely destroy something.
You'll need to remove all traces of water and the contaminants that were in it - I'd probably get a bottle of meths and just drop the whole lot into that.
It'll remove the contaminants and displace any remaining water with a fast evaporating alternative.
Meths can leave a 'film' and, to be honest, I'm not entirely sure what it is.
It does come off with switch cleaner and a 1" paintbrush though.
Once everything's been washed down, dried out and reassembled then you stand a chance of fault finding.
