We conducted two MHD tests last night. First first produced no data. We had conducted a dry test before the firing. A dry test is when we run the data logger on the fully prepared system however the motor is not fired. Instead a battery is connected to the plates. We check the and if you see the batter voltage you know the system is ready. The dry test was successful but there was no data from the live firing. While disassembling the system we discovered that the ground wire on the data cable had broken. It was apparently hanging on by a single strand during the dry test and came off when the test rig was rolled out to the parking lot.
On second second run it unit just plain old wouldn’t fire. After four hours of epic ninja battles with the test gear we got a good test. Sometimes your gear just gets old. This was firing 97. I’m just glad everything starting failing all at once rather then put us in agony for weeks.
