Finally stayed on constantly for a day. then went out and none of the interior gauges,radio, or accessories work. Charged batteries and checked alternator all good. Everything works now but light still flashes
SOURCE: 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).

All of you accessories can't run from the battery. The alternator has to produce 13-14 volts to you battery to keep the battery charged fully so all the accessories will work. Soon as a power source is powered on it will drain the battery quickly if the alternator isn't putting out. I would change the alternator. Honestly, If you have a shop close by that rebuilds alternators, this is the way I would go. Here in my home town, a rebuilt is $95 as a rebuilt from auto zone is $140-170 and comes with the same warranty. I use a rebuild shop for all alternators and starters. Cheaper and have never had to take one back compared to auto stores.

what you need to do first is find out what was the original problem. If you had bad batteries only,, then this should not of happened, But if you installed a defective alternator or did not disconnect the battery before replacing it you could of damaged something importtant if a short accured that did not pop the main fuse first. All the imputs for all functions come thru computers and only a proper diagnostic is going to find the problem. since you already stated you checked the obvious. Your going to need a diagnostic scanner to proceed.

Hi
Can I have more info.
1. is there any pressure in the fuel tank when you remove the cap?
2. have you tried leaving the battery off for 24hrs then reconnect?
3. has any other work been done recently such as starter motor or altenator etc, for the battery to drain it could be a parasitic electrical drain this can happen if a relay is sticking, a module is not turning off, or a shorted diode in the alternator itself is faulty.
get back to me.
Regards
Dan
