97 LeSabre Headlight Issue

Hello gentlemen. My driver side lowbeam went out the other day. Simple fix, so I bought a new bulb. On install the bulb didn't work. Bad bulb I thought. Before returning said bulb, I put a meter on the bulb plug and found 11+ volts. I put battery charger power to original bulb; and it lit. I reinstalled the bulb and even mounted it to the lens assembly.... nothing. Removed bulb and tried a little bulb grease.. nothing. Any help out there? It all seems to work, just not together.

Check for proper ground

That was first thought too. However, if I get power to the meter, don't I have a good ground?

Volts should be 12.6. I second Ed. Bad ground. What are the ohms of the ground wire at the bulb plug to the negative battery terminal? It should be less than 1 ohm.

The volts should be 12.6 if the battery is fully charged. You may be contacting with the meter probe better than the bulb base.
While the grease is usually a good idea, be sure everything is clean if you've not done that yet.

I checked Pauls ohm idea, and with the engine off, I got 0.0 on the ohm meter. I then removed the terminals from the plug housing and checked power with meter and found power at every area of terminal. I checked the overall condition of the terminals, cleaned with electrical spray cleaner, tightened prongs and reassembled. No light. Parts store has replacement plug that seems to need splicing in, but i'd rather buy the assembly that goes to the main wiring block and that powers both hi/low beams. I'm at a loss here.

It's working now, but I don't beleive it will last long. I checked the main block connector, and found it pretty corroded. The terminal for the problem light is rusted and about half gone. I sprayed and scraped the best I could, but the light in question terminal felt as if would break if given too much attention. I reassembled, and with a bit of wire/connector push/pull, it worked. Is there a complete new main block assembly available? Does that plug in somewhere down the line, or is it a splice job? Thanks for the help so far.
