dash electrical issues -gauges going nuts, radio turning off, brake service lights
all of a sudden today i started experiencing very random, various electrical issues. here are some of the things that were happening:
*my digital odometer was flickering
*my radio was turning every few minutes (only would go out for 2 or 3 seconds, then come back on)
*my "Brake" and also my "ABS" services lights were on and off
*my voltmeter would rise up to about 1 notch past 14 (midway) while i would accelerate, and then drop back to 14 once going a steady speed. this wouldn't happen all the time, just randomly...most of the time it is always at 14, even when accelerating
*when i turned the jeep off, it would basically act dead (normally radio gauges will stay on, and power windows will work until i open the door). i then tried to turn the jeep back on, but it acted like it had no power at all (as if it were in Drive or something). however, once i put my foot on the brake it let me start it. also at this time my radio had been "reset"...all of my preset channels as well as my clock was reset.
*my speedometer was also bouncing around....like rising and falling from 10-60 mph, when i was only going maybe 15.
does anyone have any thoughts on what this might be? i have a 2000 grand cherokee, limited, 4x4, with the V8.
