Hello again,

Ignition Setup

So, my Ignition setup should be more or less like this:

Can you guys confirm?

Yes, except that ideally you'd ditch the on-board current limit resistors, and provide one each inline to each of your ignitor inputs to *guarantee* they get switched correctly. Corbon did it this way in his DIY style jaguar build. His motherboard has 6 high power resistor locations, and is fed from the Jaguar with resistors removed.

Updated Igntion Setup

Here is the updated diagram:

Questions/doubts:
  • The resistors are the same Yageo FMP200FRF52-160R , that you can get on DigiKey?
  • Any tips on desoldering R91, R92 and R100?
  • Is wire be enough to reconnect ?

Injection Setup
  • Any tips on soldering the Ohm jumpers?

In order:

* Yes
* Cut the long leg at the top, heat the bottom of the other one while GENTLY pulling (strong pulling will destroy the PCB just prior to full melting) and the resistor body will come away. You can then use long leg you cut off at the top to bend over and poke down through the hole forming a bridge. Or any other scheme that works for you and is physically reliable.
* Covered above.

Tip: Position one well, hold it still, and solder the inner end of it. Repeat, soldering the far most exposed edge carefully with minimal solder, nearly dry. Repeat repeat. Once all have one end secured and are aligned well, float the remaining joints starting with the first one, and then reflowing the rest as you flow the dry next to them.
