Make sure the ballast is properly grounded. I had this problem when I was setting up my lights and it was frustrating. I had mounted the ballast on plywood in my light setup and so I needed to run a wire from the frame of the ballast to a common ground and voila, it worked

this is the fixture so everything was properly wired. I bought a new ballast and replace it and it still does not fire up. For the old ballast, i see a flash in bulb so i know all connection are good. Just want to test to see if the new ballast is defective, so i test the output voltage.
Right now my volmeter reads only around 70 mV AC so i am thinking the new ballast is defective, my old one also read very low output Voltage as well

ya the ballast is most likely dead. The reason for ballasts is to brovide a starting voltage, and yet limit current. Lamps, being Flourescent or MH (HID) they have a lot higher striking voltage than running voltage. Some bulbs take 600v+ to strike the arc, yet less than 100v to maintain the arc. I would be very carefull measuring the OCV (Open Circuit Voltage) with a meter rated less than 1000V.
