[DML] Re: Battery condition

The "proper" way to troubleshoot the starting/charging system is to
start with some "known good" components. The most prefered method is
to remove the battery, slowly charge, clean the terminals, and test it
separatly from the car. Once you know you have a good battery (either
because you tested your old one or replaced it) you can now do some
tests. You can check voltage drop across cables, starter current, and
the charging system. If you have bad/dirty connections, it can cause
the battery to be chronically undercharged which is very bad for the
battery and the electrical system. The alternator should be charging
even at idle. If it is not then there is soemthing wrong. If the
battery is good it will turn out to be either bad/dirty connections, a
wiring problem, or a problem with the alternator. It is critical you
use the proper point to test the elctrical system relative to
"GROUND". On a Delorean this is more important than most cars because
of the fiberglass body so you must always be sure you are actually
measuring from a GOOD GROUND. If in doubt always go right from the
battery negative terminal. This is the ultimate ground reference.
