Fixing the Thomson transfer switch

Poor thing got stuck in generator position and couldn’t go back on line… the problem only became apparent watching the mechanism cycle.
ignore the fact that I say “short of the limit switch”, it should have been “final position”. whatever. brain cheeze.

The limit switch was getting pressed early, causing the robot arm to stop moving with the breaker juuuust on the edge before actually closing. The reason for this was that the locknut got loose on that screw that activates it and the screw backed out a bit.

I readjusted it and tightened the nut. I then used some of the same nail polish I’m wearing in the video on the threads to keep it from backing out again.

Then I sang to it.

Dumbest connectors ever.

These pieces of turd infect some Harris Broadcast products to this day.

Sure, IDC connectors seem like a good idea at the time except… A) they use them on stranded wire, making them failure prone, and B) they put them on cable assemblies that experience vibration from blowers….

It’s a surefire recipe for very difficult to troubleshoot problems.

A useful continuum

Chances product will work efficiently, safely, and properly, as designed and advertised <--------------> Number of superfluous high brightness blue LEDs integrated into product

I have yet to find an exception to this rule.

Flaky play/pause or cue buttons on a Denon CD player?

Solution :
A) disassemble the player and resolder these cracked solder joints below the affected buttons
B) instruct DJ(s) to not pound the buttons
C) if B is ineffective, pound on DJ until it is

Shown here : dn-s1000, play button is in the far corner. I’ve seen the same problem on most Denons and a couple of Stantons.

 

When I originally posted this, my phone autocorrected “Denon” to “Demon”. Boy, when these solder joints go bad… you’ll think there IS a demon in your CD player, bent on ruining your DJ sets… 😀
