Your ballast has shorted out. I have found that when approaching an unknown 
ballast that if you measure the voltage across the two bulb sockets and it 
is about 5- 10% HIGHER than your line voltage, then the ballast is OK. This 
avoids blowing up valuable or hard to replace flourescent tubes. EG, for 
115VAC line you would see 120VAC or more, and for 220VAC you would see 
230VAC or higher. If the voltage is the same as line, then the ballast has 
failed. Ballasts also read about 10 to 15 ohms resistance, but this test is 
not as conclusive.
