Simplex 2400 JF
Looking for some assist.
This is a Simplex 2400, please see attached pictures. Here is the problem. Upon inspection of the Master Clock today. There are two area where there were at one time an electronic component that was connect across two terminals. The components have "vaporized" due to a heavy surge or spike. The only thing left is the wire leads connected to the terminals. The one device was across the AC input. (Hot and Neutral) The other was in the upper left corner of the Motherboard. I can only guess that they were either MOV's or Capacitors. The Master Clock seems to be working just fine. At this point in time there is no way to determine when this happened but it really took a hit. What I hoping for is that some one (Simplex Tech) would know what device might have placed in these areas and maybe what values they might have been. Not an easy task to be guessing at. Thanks, Les |

I may just leave the system as is since it does seem to be working Ok. Thanks for looking. Les |

Since we're guessing, I'd be almost willing to bet that what blew up on the yellow terminal block was an MOV. They often go catastrophically, and the damage to the terminal block says that something pretty violent happened there. The other one is kind of interesting because of the smudges on the wires and the horizontal band of clean between the smudges on the wall. I have no clue what might have done that! Are there any pieces left in the box? -- JF |

Other than that, it appears that all has vaporized. The orientation of the pictures seems to be rotated 90 degrees to the right. I think the ?device? was mounted behind the wires and when it went poof'e the wires got scorched as well as the back of the can. Thanks for the link I will check it out. Les |
