    battery light comes on even at highway speeds. voltage drops to 9v and sometimes it recovers and reads 14v.
    Replaced battery already. Is the next step the alternator?

Take volt meter check voltage on batt.while truck is idling,voltage should be between 13.5-14.5v,turn headlights on it should stay in that range if it goes below,check for bad wire connection at alt.,if conn. are ok,theres a good chance alt. not charging properly!before doing test make sure batt.is full charge!

Battery light comes on after starting but goes out when rpm is increased. I plan on replacing battery tomorrow but would like to know if I should change alternator too.


After you change the battery, check if you have approx 14v when the vehicle is running. You should have around 13.5 min. Turn on your a/c, lights, wipers and check again. If the voltage is slowly dropping below this rate, your alternator is on the way out.

Instrument panel went dead


Checked Every fuse in the fuse box (no small task).This includes #4 - Power point Instrument Panel, #14 - Day time running lamps (auto lamps doesn't work nor does auto lock), #27 - ignition switch run feed, #35 - Instrument Cluster, #41 - Instrument Cluster, #42 - Delayed Accessory, #45 - Ignition switch run/start feed, #102 - Door locks body security module, #103 - Ignition switch, #110 - Ignition switch, & #116 - Ignition switch. But I also check all other ones as well, they all register OK. AC panel & radio work. Turn signals work. Mileage does not work, trip computer does. So, basically, everything works except auto head-lights, auto locks, and the dash cluster (no MPH, RPM, mileage display, Fuel, Temp, Tran Temp, and Oil Pressure).

Speedometer, tack, fuel gauge, temp gauge have erattic behavior


With Ign. off what is your batt.voltage reading than take neg. cable off and take another reading 5 min. later. It sounds like a intermitten short, try to isolate voltage drop when acting up. Gauge circuit would be a good start. Schematic would be helpful.

Could be a problem with your ignition switch. This happend to me. Battery shown it was charged, then while driving, the gauge slowly would drop. There could be a wire that is shot inside the ignition switch.
