Check your brake wires connections because it seems that some wires are inccorectly installed and need to to inspected and refixed

Hatterasnc,
You're alternator has gone bad and the vehicle was running on battery power. The "clicking" sound is your now dead battery that does not have enough power to turn over the starter. You might also want to check your power steering pump for leak. This is a know problem with early LS400s and will most likey be the cause of the alternator failure. I just dropped $1050.00 to fix the very same promblems you have.

Try rotating the ignition switch slightly after you turn it to on and see if the lights come on...had the same problem and changed the switch fixed the problem...

the track off light will come everytime yhe check engine light comes on. this is normal. you need to have the check engine light checked first.you can go to your local parts house they will scan it for so you at least see what area you problem is in and then you can start from there. let me know lf you find out youe engine codes.

I would inspect your wires at the starter. If you live up north then corrosion is bad, clean all wires going to starter. then clean wires to back of alternator. I seriously doubt that alternator is the problem, but if you remove it you can have it tested for free at most parts stores.
Testimonial: "Thank you! You was right, it was not the alternator, it was a 125 AMP that was blown."
