My 1997 Lexus LS400 won't start so I replaced the battery and it was good for a few days, then the lights got dim and wipers quit so I replaced the alternator it did good for a while now it's doing the same thing. It's worse when it's wet outside. My power steering fluid was leaking on the wireing harness also.
Insure the drive belt is turning the alternator properly. When it is wet outside the belt will slip quite a bit more if it is not tensioned properly. Also ....the ground from the battery post to the engine block needs to be checked to insure a great connection. Any resistance in the ground cable OR the positive cable from the alternator to the positive post of the battery will cause your issue....dampness will make these issues worse.
Would check output of alternator when damp/wet outside...and find a tech that KNOWS how to perform a voltage drop test on the battery cables and the alternator output wire that goes back to the battery.
Hope this helps!

I HAD THE SAME PROBLEM WITH MY CAR. 93 LS 400. THAT WOULD BE YOUR FUEL FILTER OR THE FUEL PUMP GOING BAD. TRY CHANGING THE FILTER FIRST. THE DEALER TRIED TO CHARGE ME $980 TO CHANGE FUEL PUMP.
