Subject: Right Coil is leaking 

 Today Maico and Travis completed and electrical test to determine the right and left coil on TM4. The left coil is the negative side. From there Maico pumped on both lines for a leak test. The leak cart pumped down to its lower limits on the left line and there was no response when sprayed with helium. The right line would not pump below 2.5 x 10^-2 Torr and had a base leak rate of 3.3 x 10^-7 atm*cc/sec (this indicates a massive leak). Without spraying helium the leak cart responded and peaked at 1.9 x 10^-6 atm*cc/sec. Attached is a picture of the module indicating the line.
