some case you may have have a bad switch that can affect or loose connection somewhere.
What the voltage rating on the ballast and as I asked before please post the ballast number we can able tell you and what wattage the bulb as well so we can assit you to make sure you have matched set.
If you have 13 watter you will have to pay attetion if that is "preheat " or " rapid start or instat start there is couple verison of that so therefore that the main reason why I ask for ballast number cuz I will able determeted to see if that is a really matched set there or not.
