Default High voltage

~HELP!~
'06 Tahoe Z71/5.3/4×4/216,000miles
Started with increasing voltage so checked and was told needed a new alternator. Replaced it and the issue has gotten increasingly worse. It not only red lines but is maxed out. When this started and i turned off the vehicle the voltage guage would stay at roughly 12 now it goes from˝ inch passed 19 back down to 19. Has anyone had similar issues?



Thanks in advance

Put a volt meter on it to verify the charge rate.

Are you having slow crank at start, could be an indirect short your alternator is feeding?
