still having problems, need advice please

it's in auto that's why you are getting the #'s repeated



push the range button and it will set the range and you will get solid #'s
OK Brian, here's the numbers now, LOL
this is at idle, I haven't went up to 1500 rpms
on my grounds: 5 at battery, 6 at frame, 4.8 at firewall, still sucking.
14.2 at battery, 14.3 at alt post, 13.6 at ballast?, and 10.15 at coil?
when the fan kicked in I took readings at the battery and alternator, 13.8 at battery, 14.04 at alt post.
had to edit, the number at battery in a/c is zero
