We are having repeated failures (3 now) were the MS just shuts down. I can replace the fuses, but I wondering why this continues and if this is indicative of a bigger problem. I would like some advice how to troubleshoot. Thanks!

Thanks Soccerdad and James.
I replaced the fuse and connected a brand new rough pump to the instrument. I also checked the diffusion pump and changed that oil for thoroughness. I was excited when the MS came back to life yesterday afternoon. I allowed it to pump down over night and this morning was able to get a good Air/Water check and tune and even a 2 injections. During the third injection, a few seconds after the detector turned on following the solvent front, the MS died. The fuse blew again. I saw errors 6: "Difficulty with the HED supply. Difficulty in the mass filter electronics" and then error 204: "Difficulty in the mass filter electronics. There is no emission current. The high vacuum pump is not ready."
After the instrument cooled down, I opened up the source and everything was connected and both filaments were intact. Any other suggestions or help is most welcome.
Thank you!
