You can test the ballast with a multimeter. Keep the ballast hooked up to the harness, unplug the bulb, turn on bike power, and check for voltage at the ballast power output plug. The side that connects to the bulb.
That's a generic 35W HID ballast. You can find similar replacements super cheap on ebay, if you want to go that route. They all have standardized plugs, both input and output, so any brand should be interchangeable with what you have.
