Messy
Take your car across the river to Autozone and get it scanned for any codes, abs etc, apparently they offer this as a free service state side.abs could be a bad sensor /wiring problem at wheel.you`ve read the lighting issues ,so you know where to look for that problem,up front. how old is your battery. It does sound like you have a bad electrical connection somewhere and the water is creating a problem . your alternator is likely still ok if .. if your battery is good something is drawing power and killing it. your alternator and battery may also get a free check up.

loose wire and corrosion are what I'm thinkin.

loose wire and corrosion are what I'm thinkin.ya most likely but if these checks are free why not get it done ,right ? with the abs light they can pin point which wheel is acting up
