I have a 1992 jetta and I'm having a problem with it charging the battery... When running with the battery terminals off I read 15.1v and when I put them back on the battery with car still running I'm only reading 12.2v but that was with a fully charged battery as well. I should be running the same 15.1v. I'm just at a loss of what could be causing this...
1999 2500 cummins 53 series block (cracked) rebuilding it not sure what all is gonna be done yet but want to put up some big numbers before i decide to chip it out.
