Okay well i finally finished tying everything up and went to start my 1984 300D and nothing happened. No lights, no lights on the dash or anything.

I'm guessing it's a bad connection, or bad ignition switch. I know that i need to use a voltometer to find the problem but dont know how. What setting do i set it on? Where do i test?

This is what i've worked on:

1. Replaced starter
2. Replaced starter cables
3. Replaced Voltage Regulator (fixed missing alternator bolt)
4. Replaced Belts
5. Flushed Radiator
6. New Battery
7. New Upgraded Headlights

Other problems On The List:
1. Oil Leak
2. Sun Roof motor and cable need to replaced
