optima is now made in mexico, not as good as they use to be.

I don't know what kind of MM you have plugged into the cig lighter, but it could be wrong.
use ONE MM for checking voltages.

resistance would cause a volt drop to the battery IF the cig ltr MM is correct.

you have to CLEAN the connections. check the ground strap to the body at the battery.
the tranny ground needs to be clean. do just look at them or measure the resistance.
measure the volts at the starter.
what is the batt volt with engine off.
measure volts at batt from the + to - then from + to chassis with engine on.
does the ALT light come on with engine off and key on.
