[DML] RE starting and running

Hello JP.

If the battery and alternator are talking, so speak, its time to look at
grounds.  Because  you measured 12.5 at the battery  and 14V at the
alternator, start looking at grounds inside the car. Measure between the
alternator body (supposedly a ground) and internal grounds (lights,
switches, etc.).  Because your voltmeter draws little or no current,
compared with what's going on with the regular circuits, you can extend one
or the other leads to the meter with a piece of wire, whose gage is of
little significance.

When you see differences of more than a few to a few hundreds of mill volts,
look at a different ground.  Differences of greater than 200 mV (0.2V)
should be investigated (cleaning up contact.  I suggest including star lock
washers will penetrate the connecting surface and thus make good metal to
metal contact.

After the ground, then time to look for resistive paths in the +12 leads.
