I have a 2005 LS430 (like most people here) I need some help, I live in Florida and last week I was driving and it started to rain and the water became standing. I had to drive through it to get home, since that moment my car hasn't been right. It won't start up anymore. At first i thought it was the battery, i purchased a new one from the dealer. I installed it and it started up first try, i drove to a friends place it was still starting. I made it home and parked the car the next morning it won't start again. It just clicks when i try to start it up. This was over the course of 4 days. Does anyone have and suggestion.

Your alternator might be toast. I would have it tested. Have you tried to jump start it?

If the alternator gets wet does it short itself out, I was under the impression that if it dries it should be fine but the water out here was kind of deep. Here is an idea of how high it was.

Yes, water can damage the alternator. Especially that much. I think this is your problem because you replaced the battery and she started and ran but if the alternator is not charging the battery correctly you drain the battery and are back to being stranded. If it turns out to be the alternator RockAuto has good deals on them. Denso is the way to go.

Okay all the electrical components turn on no problem. When I try to engage the ignition there is one audible click, and nothing it just stops after that. I try to see if i can have the alternator tested tomorrow.

The clicking is a classic sign of a nearly dead battery. Try to jump start it and have an auto parts store test it.

I'll try that in the morning, is there a DIY for an alternator replacement, its not a continuos click just one click then nothing happens. I'll have the alternator tested hope that works, not sure if the dealer is willing to cover it.

Before testing the alternator (generator), take a look at the 2 fuses circled in red below to make sure they are not blown.


If the fuses are good, then test the alternator.

It's an easy DIY - Take a look at this post https://www.clublexus.com/forums/ls4...-ls-430-a.html

I just finished having everything tested and my results were completely fine. The starter, the alternator and the battery all appear to be working in optimum condition.

That's good news. Is the car running OK? How did you get it started? Jump start?

Yes I jumped started with with the battery in my GS, I so far it is running fairly well. I'm not sure what is going on with it I took apart the fuse box checked everything and couldn't find a problem. I had it tested so far so good. I'll keep you guys posted. Thanks a lot

Maybe it finally dried out. Let us know.

From what you've shared, it sounds like your battery was draining faster than your alternator can recharge it. Another possibility would be that the new battery your purchased was not fully charged to begin with. After starting the vehicle, you drive a short (assuming) distance to a friend's house, so the alternator did not have time to fully recover what you used to start the car previously. Then you drive a short distance home and run the battery down even more. Just speculating here!

Hey I drove the car all day yesterday now i go to start it up and the same problem just he click and no start. Everything that was tested came back good and clear. I have no idea what this could be. Please if you think of something let me know. I really think its a fuse i just have know idea which it could be.
