Battery got wet, car won't start, now what?
Hey all, I left my car outside this weekend and it looks like the heavy Florida rain came down so hard that it caused water to get into the battery compartment. Not knowing the battery was wet I tried to start the car; it didn't start obviously...... I now have the battery removed but am wondering if the water might have done any damage to the car, such as fry the ecu, damage ignition components, etc? Are there any precautions I should take or is there anything to look out for?
Thanks
Thanks

Just curious, is it a coupe or a cabrio?
How much water was in the battery compartment? Its not air tight to begin with but was it sitting in 6+ inches of water? Was there noticeable water accumulation anywhere else in the frunk?

Maintenance 101! Clear your drains under the front cowl covers and that will never happen. Sounds like you should get everything dry and retry. No reason a battery should go bad even with that much water backed up in there....the posts are on top. You need to pull your carpet and look at the ECU, could be water or corrosion there..simple check to see if the carpets are wet under the seats. Check your ground connector at the battery. Reconnect the battery after checking to see if it has 12+Volts, then check the jumper post in the engine compartment to see if it has 12+V. If it doesn't crank, then replace with a good battery (or try a jump), check and try again. Could be an ignition switch problem that just cropped up at an unfortunate time...but if it cranks and does not start, then replace your CPS..most common problem for not firing if all else is good.

The car turned over the first time I tried to start it last night; but it died as soon as I engaged the clutch and put my foot on the gas. This morning when I went to start it again it wouldn't turn over this time....... Although the volt meter did show that there was no juice..... What is the pendulum? Perhaps I should check this..... I have the EVOMs airbox so perhaps water dripped into the filter area. Gonna check that right now.

Maybe you just need a new battery?

I'm guessing you are right. I forgot to mention that my car is set up as a track car and it has an Odyssey PC680, which is about the size of a large sandwich lol. I'm always careful to make sure I never leave doors open and lights on (because this battery drains FAST), but perhaps the water damaged it?

I use a PC680 in my Spec996. It doesn't take much to discharge those things. Really the only way I've found to make the battery hold a charge is to pull the kill switch when the car isn't in use (as in overnight). There is just too much parasitic drain in the car.

Thanks for the reality check, you are 100% correct. I've been avoiding installing a kill switch for a loooooooong time, for no good reason other than laziness, and the only thing I've gotten in return is multiple dead batteries and lots of headache. I ordered a new battery but have the current one hooked up to a charger. Hopefully it fires up in the morning..... I will post an update.
