Noting that the driven alternator pulley, being smaller than the  driving 
pulley (AKA, the balancer) will be going faster at a given idle RPM than  the 
balancer. You should usually get some charging at idle, with an alternator, 
 depending on the engines idle speed.
The OEM flashers are heat activated heat-interrupting switches, based  on 
the amount of current going through to light up the lights. When the current  
in the circuit reaches a certain level, the heat inside the "can" 
pushes/pulls  the contacts free and the lights go out. Then the circuit cools off and 
closes.  (Flashing) That is why a dead bulb will often stop the whole side 
from  flashing. The remaining two lights light will just stick on, since not 
 enough current is flowing (activating only two filaments), to  heat up the 
can inside.  Low voltage, for whatever the reason, usually some  resistance 
in the circuit, will drop the current flow and the lights will  stick on. 
Usually all three lights will be on, but dimly. -Seth

Low voltage.  Clean the battery  terminals first.  If not cured then check 
idle speed--if too low the  alternator won't charge.  If the idle speed 
meets specs, check belt  tension.  Then the final check is alternator output.  
The alternator  pulley needs to turn at about 1500 rpm to charge.
