Warning Lights????

So I"m bombing down the highway in my 1990 3.0 and I look down to see 3 warning lights! The Brake(!), the Battery Symbol, and the A/T Temp light????????? After pulling over and checking the basics, I decide to keep driving. The lights eventually go out...but now they come on periodically. Any ideas on what is causing this? My first guess is a loose harness or a short somewhere...anybody have any experience with this? Should I be taking the truck to get a diagnostic?

Any help is greatly appreciated,

Aero

If the brake and charge lights come on during revving of the engine then it's a sign that the carbon alternator brushes require replacing as this is the mileage for them to wear out. In alternators the brushes wear out on average every 140-170 000 miles where on the dashboard the brake & charge light both come on at the same time. About half of the auto electric shops in your local yellow pages sell carbon alternator brushes and copper solenoid starter contacts for about $5/pair.Another way to verify that the alternator is not charging is while the engine is running bring a metal screwdriver or any metal object near the alternator and if the alternator is working properly then it should act like a magnet and grab the screwdriver.

Thank you!
Would this cause these lights to come on intermitently? It seems to be only at higher speeds...is this typical?

Also any hints or suggestions on getting the alternator out....do I have to remove the distributer?

Thanks again for all your help.

Aero

I have a similar problem, if oyu could call it that. When on the highway, my check engine light comes on and then goes off within 10 seconds. It continues to just come on spuratically as long as I am on the highway. As for changing the alternator, it is very easy. The alternator is located on the driver side on mine, which is a 22RE. This is pretty much the same for every vehicle. The alternator on my chevelle come out the same way. There is a bolt on the top of the alternator used to tighten it the alternator to the bracket. Take that out completely. Now you should be able to move the alternator from side to side, allowing you to take the belt off of the pulley. There will be 2 wires in the back. Remove them, one will be a plug and the other will be under a nut, 9 mil if i recall right. Underneath the alternator there is a long bolt that goes the entire length of the alternator. Put a wrench on the front and a socket on the back and remove it. Now the alternator will just fall out. It may be kinda tricky getting it completely out of the engine bay, but just wiggle it around. I believe it comes out the top the easiest. My advise on the temp lights and whatnot is to go to your local autozone and ask to borrow a codescanner. They will most likely have one, and if not, they can get it for you. I hope that this helped, Sam.

You don't need a code scanner to read the codes in the computer. You can use a paper clip and bride the two inputs as indicated unter the hood. There will be label telling you which ones to bridge. This will make the check engine light flash the codes out. All the Haynes & Chilton books will tell you the codes. Sounds like alternator/battery issues to me.
