Hi All!
I have a 2005 Tahoe that was setting for a while. It was running fine with no issues untill I parked it because of a blown rear brake line. The battery went dead co I charged it and got it running. I noticed the Speedo needle was jumping just setting there idling and also driving. I also noticed the battery Light was on. The alternator seemed to be working because it was showing around 14 volts. I shut it off and disconnected the battery. I grounded the positive cable to clear the codes. I reconnected everything and started it. I got the same results. So I connected my scanner and cleared the codes. Didn't help...
Has anyone ever had this issue before?
Thanks in advance,
Brian
