Optoma HD33 bulb questions

I bought a used HD33 I was told It just needed a new bulb. I replaced the bulb with a new housing and original Osram and it has solid orange with flashing red. This indicates Lamp fail. There is no light or anything. Thinking I had a bad bulb I ordered a new bare Osram bulb, installed it and the same error. In my testing phase I tested the power output to the bulb and it’s steady at 96.5 volts is this enough voltage to fire the bulb? Is it possible I put the wires on backwards on the bulb. Should the main power come in around the coil of the bulb to the top wire then down through the bulb chamber and out of the bulb. The bulb has no + - marks. Thanks
