    a few things i have had take out the 1st/2nd ball lights:
    1.something fall into the chassis by the heat sink with the three diodes.
    2.A bad diode
    3.a bad klixon
    4.bad pins in the green plug either side
    Sometimes we have to do stuff to get by....Just go back and do it right when the "by" has passed!!

      Another possibility to add to the list. Earlier this season I had a chassis (MP), where all my circuits in the chassis for ball lights tested good. After doing research of the chassis schematics, found that it's power source comes from the T1 transformer, I changed the transformer out and regained the masking unit lights.

        How did you hook up the test lights?

          Made up a test unit using a Elco plug and using 2- 24 volt LED,s..

          Common Earth pin 29 to gold spade terminals on LED,s

          pin 24 to 1 LED and 25 to the other, onto the silver terminals

          pins 2 and 28 wired up to a off/on switch

          I tested all the chassis,s and found 6 not working
