try using a sharp pin point pic tool to work the broken fastener in reverse, unless you cross threaded it, it should walk out since all you’ve done is essentially pop off the head of the fastener.....put a tiny drop of penetrating oil on the broken fastener to aid in it’s removal....it takes time and patience, but I’ve walked out a many a broken rod bolts this way......Pat 

Hi Pat,

Sounds interesting, however I don't know what a pin point pick tool is.  Could you tell me more?

 

White it white, it's nominally a 3V LED.  I use hundreds of them, all of the bright white, warm white, amber, etc. LED's have pretty much the same operating voltage.  So, if you have 12V, and you want to run the LED at the rated 20ma, you'll need a 450 ohm resistor.  A 470 ohm resistor is a standard value and it's perfect for this task.  FYI, the resistor is dropping the voltage from the 12V to 3V, so it has to drop 9 volts.  At 20ma, it takes 450 ohms to drop 9 volts.  The resistor will be dissipating .18 watts, so I suggest a 1/2 watt resistor in this example.

Thanks John,

I am going to ask if anybody knows of a schematic for the shorting plug.  Maybe the idea of making on is reasonable...
