recently is in vogue the use of glow plug n°8 to ignite ejection charges. See Aerotech electronic forward closure or NO MATCH
Both use a CR123 3V lithium battery, but glow plug must be supplied with lower voltage (1,5V is written in Electronic forward closure manual).
In this manual you can see the photo of both sides of PCB. It is clear that one side of the glow is directly connected to + of battery via ejection canister. The second side of the glow (the one with the wire soldered) reach the PCB, pass through the diode D3 and reach the (I think) power mosfet.
The one million dollars questions are: How the voltage is reduced? With a PWM control of the mosfet?
What is the function of the diode D3?
