#27 of 47 Re: Electrics chaos [rbb50] by vguthrie Sep 21, 2008 (8:16 am)
Replying to: rbb50 (Sep 21, 2008 7:40 am) I own a 1993 LS400. I had a similar problem but not as crazy, found that there is a cluster of wires in the trunk hinge on the drivers side. Constant wear from opening and closing the trunk one of the wires had been cut. Everytime I applied the brakes the reverse light on the panel would lite up and the car would "clunk" as if it was trying to go into reverse. Don't know if this will help but there are alot of wires in that cluster something could be cut and causing your car to go haywire! Replies to this message: j7wild (Sep 21, 2008 9:21 am)

#29 of 47 new battery for 2001 LS 430 by acco20 Sep 30, 2008 (1:46 pm)
I will soon need a new battery for my 2001 LS430. I have checked the battery itself and I have checked all the manuals and can not find any numbers or discriptions that would lead me to buy the right battery. I mean what size, cranking power etc. I am concerned when I do not know exactly what I am looking for. Can anyone help??? Thank you. wwest...are you out there by any chance...

Replying to: acco20 (Sep 30, 2008 1:46 pm) I have been buying my replacement batteries at Costco of late and simply rely on their cross-reference catalog.
#31 of 47 last battery I bought by j7wild Oct 01, 2008 (6:56 am)
for my 1992 LS 400 was a 430 cranking amp battery and that's because the guy at Auto Zone told me I needed something that big for such big car Replies to this message: wwest (Oct 02, 2008 8:12 am) j7wild (Oct 02, 2008 8:24 am) wwest (Oct 05, 2008 6:55 am)

Replying to: j7wild (Oct 01, 2008 6:56 am) The biggest "challenge" for your car battery is in cranking the engine. These days most starter motors are reduction geared and therefore require less cranking amps than in days gone by. Additionally with all the electronics in control, especially EFI, engines simply start a LOT quicker.   I would wager that a small garden tractor battery would supply enough AMPS to start an LSes V8 but accordingly would not have a very long life.

Replying to: j7wild (Oct 02, 2008 8:24 am) No, just good salesmanship...   Except for lightening your wallet slightly more than necessary he did you no harm.   Manufacturers of late have become a bit more conscious of weight vs MPG issues so while the higher capacity battery will undoubtedly weight more than the OEM it will also likely last longer.
#35 of 47 CD player. by wwest Oct 18, 2008 (8:02 am)
The CD player in my brother's 91 LS400 will not change discs nor open the CD door but will play the CD currently in position. I traced the problem down to a pico fuse in the "head" unit. Does anyone know of a shop that specializes in Lexus radio repair...??
