Speedometer needle over 160MPH!??!?!
So my neighbor's RX300 is giving him some hell. One of the problems though is the needle flew all the way past 160mph, and is just resting there pointing directly down. I searched this part of the forum but really didn't come up with anything of the sorts. Anyone got any clue what could be wrong? Also his battery has been draining alot recently. I thought it might either be the battery or the alternator, but both check out ok. Any help would be greatly appreciated.

How old is the battery? And are the battery terminals making good contact? It once happened to me with my previous car and battery also checked ok, but still changed it and no more needle problems.

If its staying at 160, I would say its deffenetly broken. I would try tapping the speedometer cluster with my finger when the car is running. And maybe the needle will come back to 0. And or remove the battery for a few and make sure the battery terminals are making good contact.

That battery drain is probably no coincidence. Your neighbor needs to put an ammeter in the battery circuit to determine if the drain is from an external short or one inside the battery itself. (NOT BETWEEN THE TERMINALS) I would vote for the battery. As they age, plates often collapse, resulting in internal shorts that can pull a battery down dramatically even overnight.
Are there any strange effects going on in the radio stack? RX's are well known for mysterious re-setting clocks, display anomalies, even memory dumps when battery voltage falls below something like 11.2 vdc. You still may be able to crank the engine, but if system voltage is low, all kinds of craziness can appear in the electronics. Clean and replace the terminals - even replace the battery if it is over a couple years old - especially if it has been deeply discharged a time or two.

Just take the cluster out turn it upside down for 10-20 seconds and slowly turn back clockwise and reinstall. I have seen this and and fixed it this way. It usually happens if the alternator+battery die at 70+ mph or someone just replaced the "D" light or anything on the cluster.
