Week 5 (2/1-2/5) Glow Plug Timer Relay


Got my hands on a NGK glow plug timer relay. I understand the basic ins and outs of how it works and it's role. However, I'm not fully understanding how the circuit "knows" how long to engage the timer. Perhaps we could expand on this in class? 













I am not grasping the workings of this schematic. Any input would be greatly appreciated.

    Well there are a bunch of transistors, zener diodes, capacitors, and resistors in there plus a timer circuit. It is a bit beyond me at first glance, but we'll think about it.

    Be sure to remind me in April and we'll color it and see if we can figure it out.

    Sorry for the delay in my response. I had it up and then closed your page and forgot about it. The aged brain...
