2003 Tahoe 5.3L Z
This all started yesterday but got worse today.
Yesterday The instrument cluster was totally blanked out and mirror digital temp/compass blanked out.
This morning had Tahoe warming up in driveway to leave and went out to it not running and headlights on.
Charged battery back up and started fine. Got ready to leave and while in drive I watched the Climate display go dim to blank then the clock on radio did the same within 1 min. Shortly after Tahoe just died. Wouldnt even click the solenoid. So I pulled battery out of my Yukon and Tahoe ran fine for over 30mins in drive. I went to Gas station about 7 mins down the road and on the way back home the climate display went blank, cluster hasnt been lit up since yesterday at all and all gauges dead. Engine started getting a surge like it was not getting enough power to the ignition coils. Made it home and parked it. Went to restart and got the solenoid clicking.
Im thinking shorted diode pack in alternator. And of course I cant find my voltmeter so have no way to verify alternator output. both batteries are less than 2 years old.
Anyone ever seen this before?
