I found the resistors connected to the 40184 spark gap was broken, which caused the misfire for the Prometheus. This 40184 spark gap(SG1) was installed inside the 50kV trigger generator box. SG1 is a three electrode, 2:1 gap-space, irradiated-gas-plasma switch. The switch operates in the swinging cascade mode in which the intermediate electrode is biased at one-third of the working voltage.

If you need parts or support on the "historic" Maxwell Trigger Generator 40168, you should contact David Drury at:
L-3 Pulse Sciences
2700 Merced Street
San Leandro, CA 94577
(510) 357-4610
As far as I know, the 40168 is still one of their commercial lines and even though the exact spark gap numbers may have changed over the years, the gaps are essentially all physically and functionally identical.
