I had this problem with a boost gauge of mine once... i cant really say what exactly is wrong with yours. But i'd check your ground. That is what it ended up being on mine.

I dont know too much about the Greddy one exactly.. but if its like any other mechanical boost gauge.. you should be able to hook it up to any 12v power and ground and it should light up. If it doesnt, either the connection is bad, or the bulb is burnt out.
