check for proper grounding, bad wiring. Check voltage with a voltmeter in different places to see where you are losing it. Alternator, battery, at the headlight connection, fuse box & relay (if applicable). could also be caused by belt slippage, or lights with a higher wattage than recommended.

My '91Mazda 323 dies while driving It starts fine with a boost but dies soon after Help?
Probably need an alternator. Check your battery voltage with a multimeter, without the car running it should be around 12.5 volts with engine off. Start the car & check the battery voltage and if the alternator is charging properly it should be 13.5 or better at the battery. If not check the power terminal at the alternator itself and if only battery voltage (12 or so volts, same as battery) is there then the alternator is not charging.
How do you test voltage regulator on motorcycle?
Check the battery voltage, bike not running. Start the bike (crank the rpm's up a little), voltage should be a couple of volts more than battery voltage. Check both voltage (running and not running) at battery terminals. Charge voltage isn't all though, if it doesn't stop charging when it should it will boil the battery dry.
