Hi all, first post. Was and am still having overcharged voltage issues for my car. Dash it lit up like a Christmas tree and cluster is not working rpms/speedometer.. wipers are also going off. Battery is new and coded, alternator was replaced and just today I replaced the regulator. Car is still going mental, I’ll disconnect the negative terminal for a few hours and let the car reset and see if the codes go away, but if not I’m out of options any recommendation would be helpful thanks.
