Can you give me an update? I unfortunately followed your path by buying the bulbs (waited for my IC pipes to arrive) and swapped them out this weekend. No joy. Swapped bulbs side to side and housings side to side. Have voltage to module also. Where did you end up getting your module at?

Thanks

these are the two terminals I checked, are these the right ones? There are other metal clips, but they look like they are just there to secure the bulb in place.

To ignite the bulb the controller sends around 15,000 volts to cause an arc between the bulb contacts. Once the bulb comes up the voltage drops to less than 100 volts. I've never been bitten by the starting voltage but I suppose it would be like getting shocked off of a spark plug wire. It might be dangerous if more current is involved. Also, this much voltage may damage your VOM. So, maybe it is good thing you didn't find any voltage there.

I got several inquiries about ballasts for sale, but still went with the ebay one. If you have no luck then let me know. I may... MAY part with my extra ballast. I would really like to keep it if this happens again, but I'm not sure.

good luck and let me know how you make out.
