I basically am looking for terminals where I am supposed to connect the required VCC and GND on this Glow Plug When I check the continuity using the multimeter,it comes out as a single unit. Does that mean that the glow plug is dead?

  • Dear Mechanics mods, why was this migration allowed? – cde Jan 8 '18 at 5:25
  • @cde I don't think SE's migration mechanism require Mechanics.SE moderators to sanction the migration. Sometimes the EE.SE mods will ask in chat if a question is migration-worthy out of courtesy but that is at their discretion – Zaid Jan 8 '18 at 17:07
  • @zaid users or a mod on the recipient side can reject the migration with close votes. – cde Jan 8 '18 at 20:55
  • Well, judging by the voting this particular Q&A was well-received. Not sure what you're unhappy about. – Zaid Jan 9 '18 at 2:50

    The question was migrated just in few minutes while I was editting. The basic purpose of this question was to ask how to wire the glow plug to make a hot air soldering gun and safety purpose of doing so. I was just checking if I have posted the link correctly and in mean time it was migrated. – MaNyYaCk Jan 9 '18 at 4:27

A glow plug is essentially an intentional short circuit that heats up a wire and ignites whatever fuel is in or connected to the glow plug.

Polarity rarely matters in this. But typically, the construction has the larger body as "ground" and the center pin as "vcc". There is an isolation ring that protects the two from each other, so current goes through the wire.

  • I just added the link to the glow plug. Thank you for the answer. I will try and get back. – MaNyYaCk Jan 8 '18 at 5:20

    Note that model engine glowplugs typically are designed for only around 1.5v, not the 12v proposed in the original question. They have an expensive platinum element that remains able to initiate combustion of methanol based "glow fuel" from retained heat, needing electric current only during starting (or with 4-cycle models, sometimes at low RPM's) – Chris Stratton Jan 11 '18 at 1:48
