OK... On my 68 Newport, I put the multi meter on my battery with the car running last week after I hooked up a new voltage meter and discovered that it was reading only around 12.4 volts. I got a reading of 12.4 with the multi meter,the exact same measurement as with the engine off. I am under the impression I should have somewhere in the neighborhood of 13.6. with engine running, correct? So..here is what I have done so far with no success.
Checked the multi meter on my truck and it read 14.2 just as it should have so I believe the meter is good.
Cleaned bulk head connector
Checked for power to the alt, has 12.5, what the battery reads when fully charged.
Checked continuity between field on the voltage reg and the field on the alternator. Checked OK.
Cleaned battery connections.
Checked fuses.
New body ground strap.
I was not sure how to check voltage reg and didn't come up with much on google so I just replaced the reg. with a new one. No change.
Had the alternator checked at Auto Zone, tested FAILED but they didn't seem to have the proper test as there machine did not show the correct wiring set up. So I decided to replace the alternator anyway, with no change.
This morning I brought the new Alternator to O'Rieleys and it tested good.
They suggested I have the battery checked...so I did and it FAILED. Now I also have a brand new battery. No Change ,still 12.4 when running and I don't know what else to check. So now it's time for some help.
Any suggestions as to what I can test now? Thanks in advance. BTW the entire headlight wiring harness is not connected as I had the nose off the car recently, and plan on having it off again, could this be a problem? :BangHead:
