How old is your battery? Likely battery or loose/corroded batt cable. Could also be alternator or ecm.

It could still be a corroded or loose cable. Check grounds and both ends. That is the usual culprit. It could also indicate an issue with the ECM, but I'd check the cables first. If it is slightly loose it could give you good readings but cause issues when driving on bumps, etc.

Has it been wet in your area lately? Did you have a windshield replaced recently? Check under carpet for moisture. That is the other main possibility.

new extenders for the group 31, factory harness ends thoroughly cleaned . all connections are 100% tight (checked twice).

Next step is to check the ECU for moisture or loose connections. Let us know what you figure out.
