As some of you probably have read, I have freshened up the 424 Diesel and installed new glow plugs (original style unforturnately). I didn't know about the conversion at the time. Anyways.....I also installed a new oem style glow plug push button switch. I made sure all wires were good and connections were clean, tight, and bright. When the key is on and the button is pushed I noticed that the indicator on the dash didn't heat up and investigated further. I then jumped the two wires between the glow plug switch and then the indicator heated up (smoked too) rapidly. By jumping the glow plug switch I didn't even need to have the ignition key on. The tractor started instantly with me letting it heat up for approximately 5-6 seconds.
Now why would the glow plug switch not be working? It is a new switch and when tested with a test light, one terminal has "hot power" and one terminal does not. Now in theory, when the button is pressed the other side of the terminal SHOULD be hot but it is not testing that way.
#1) Could I have gotten a bad, New switch?
#2) Could the wires be hooked up backwards, or would it matter?
#3) Does that switch require to be grounded through the dash?
