Hi:

I am not sure if everything is related, but here are a few suggestions:

Have an auto parts store download your code from the service engile light,and see what system it is pointing too. They usually will do this for free.

Your speedometer is driven off a speed sensor, in the top of the transmission.

not sure about your clock dimming, but I would have your new alternator checked out, too, and make sure it is still charging as it should.

Battery went dead so I jumped it with a power pack 350 amp. It starts but runs rough and eventually dies and all lights flash and speedometer needle jumps back and forth.


Sound like your alternator is shot. Do the test ..After you charge the batery or get it boosted if you remove the positive battery post OFF the battery and the engine dies right away your alternator if shot .

2000 lexus es300 runs fine, then battery light comes on, and all dash lights dim, speedometer goes to zero and car shuts off.


Have you tried checking the ground cables? They could be loose or damaged, and have a weak connection. It is also possible the battery is faulty. Hopefully you have a warranty?!?
Also try checking the idle air control valve, could be dirty or bad.Clublexus.com is also a real good site to check out if you havent already.

I have a 99 solara se. I have new battery and alternator but the car can't carry a load. Ac lights heater radio so forth


Not sure I follow your problem.
The alternator puts out 13-14 volts at idle but very few amps. If you turn on the headlights at idle the voltage may drop to 12 until you raise engine speed. The amperage goes up with engine speed.
Is the battery voltage at least 14 when the engine speed is 1500RPM or more ?

My 1990 mercury grand marquis was boosted wrong


Might need to check the main circuits for a blown fuse or fuseable link.
There is a fuse wire between the alternator and battery.

'91 Honda Accord LX transmission light on.


You say "standard transmission?" Do you mean "standard" as in "manual/5 spd./'stick-shift'?" transmission?

Either way, if you replaced the alternator belt and the battery light went away and the car doesn't sputter or stop, then it's the "speed sensor" on the transmission itself. The car will still drive, but the speedometer cannot read how fast the car is going (in RPM's as well).

1998 Honda Civic speedometer nervous on the red light


?? Does it move on the road ? You could have a worn out CV joint that allows the transmission to free-wheel. If that is the case, replace immediatly, or the transmission differential will fail.
