The first thing we need to know is WHAT YEAR IS YOUR CAR? If it's the '70 pictured, then we know

You may have TWO problems--you may have a bad new battery, or you may have a "drain" when the key is off

For CERTAIN it seems like the alternator is not charging.

For starters, if you have a charger, attempt to charge up the battery. If it's a small 3-5 amp, charge overnight.

Alternator:

Turn key to run, engine off, and use a test lamp or multimeter. You should have close to battery voltage at the large stud output, and at the blue field wire. Probe the regulator connector, and you should have battery there at the ign terminal. (blue wire)

The second wire out of the regulator goes from the regulator to the second (green) field terminal. Use a continuity tester or your multimeter to see if that wire shows continuity. Shake it around while checking

Now, once again, with key on, back at the alternator, unhook the green wire. At the alternator, you should have battery voltage at BOTH the field terminals. Ready up a clip lead and GROUND the exposed alternator field terminal--the one where you unhooked the green. You should get a small spark. Leave this connected and quickly---------




ok,

- checked the voltage at the alternator, 11V (battery was still low, not charged yet).
- checked the voltage at blue terminal, 11V.
- checked continuity of blue and green wire from connectors at voltage regulator to connectors at alternator, and those test at near 0 ohms.
- disconnected the green wire with key on, (there was a spark), and got 11V at both the field terminals.

- with a multimeter connected between the neg battery cable and the neg post on the battery, has a 78 mA draw with nothing on, the doors closed, and just the clock running. disconnected the clock, and had a 3 mA draw. hard to imagine that a 3 mA draw can drain that battery in a week.

that was all i got to, will test the alternator tomorrow when i can fire it up.
