Ok replaced my alternator and fixed my voltage drop. My low beams shut off sometimes by them selves. When they go off flick the high beams and the lows will work again. The fuses are good but I don't know what else to check. Any suggestions?

Relays maybe? Don't remember which one are which but I'm sure you can figure it out as they are listed on the fuse cover.

Yeah, they're the two black ones next to each other. Swap 45 and 46 and see if the behavior changes.

DRL relay is a good thing to check. But i would check for proper voltage output from the alternator first. Should be around 14.2 volts dc. Did you replace the battery too? Bad alternators can kill an otherwise good battery.

Also check underneath the red and black boots for corrosion. Check the battery bolts for stripped threads or corrosion.

Last step would be to reseat the connectors at the back of the headlight switch. Another thing to think about is the turn signal stalk. The low beams turn off if a turn signal is present.
