Discussion and questions related to the course EFI Wiring Fundamentals
Any hints on how to physically ground the wire shield without soldering? Are there any special crimps available to crimp on the shielding?
Crimp the shield to a wire. Gather the shield braid together and twist. Treat this like a wire, and crimp it.
David is on point here, as usual :-).
I strip a section of the outer jacket back about 1" from the end of the cable, and then use a service looping tool to tease open a hole in the shielding braid, which you can fish the inner wires out of. You can then smooth out the shielding braid and treat it just like any other un-insulated section of wire :-).
Is grounding via solder sleeves not one of the few places where soldering is acceptable? With the use of solder-sleeves with pigtails like these - https://au.rs-online.com/web/p/solder-sleeves/7822059/
Yeap, solder sleeves (quality ones) are great for connecting to the shield braid. Crimping to it is also a good way to go if you don't have any on hand though.
is it best to daisy chain the shields or should each shield be passed through a bulkhead connector on its own pin?
On its own pin if you can. If you're running out of pins, it should be fine to gather more than one shield up at the connector, and break them out again afterwards, just make sure they're only grounded at one end :-).
