The car runs great, but it has a couple issues that need to be addressed ASAP.
First, when I turn the high beams on, the car shuts off. Period. Giving it gas has no effect.
Second, the drivers headlight is dim. I suspect a bad ground, but I am not sure where to start.

I ran across this post on another forum while searching for clues to cure a similar problem. Removing, cleaning and reinstalling the ground strip did the trick for me; hopefully you will have similar results..

Headlights Cause Engine to Stop: Poor Grounds. [Inquiry:] My 740 is doing something odd. I turned on my high beams tonight, and immediately the engine stopped producing power - and once it reached lower RPMs it stopped running. After turning the car off and starting it again, it did not show any problems until the high beams were switched on again. When the high beams are put on, the drivers side turn signal indicator light goes on (dimly) and the whole drivers side headlight cluster shuts off (including the parking light) while the other side remains functional. The volt meter stays put - at 12 volts of charge - even while the gremlin has taken over. Visual inspection revealed nothing - but there are a lot of wires and harnesses, and I could use a hint as to where to check for a short.

[Response: Abe Crombie] Raise the hood and look behind each headlamp on side inner fender panel and you will see a multi-spade ground strip bolted to inner fender. Tighten up the bolts on both of these and your problems will cease. If the bolt or inner fender is corroded you will have to remove the strip and clean the area.

Regardless of the origin, when cleaning ground connections, look for the ones in the back by the rear lights and behind the driver side floor under the carpet. Keep ground connections clean.
