Does it matter wire location when re-image.jpegimage.jpegsoldering coils ?

How can you tell? Power/return?

Schematic, manual.

Good idea, too bad I don't understand it but I will learn how to read it correctly quick and in a hurry!

You didn't say what pin your working on, but in pic 1 if it was wired correctly than the grey/yellow wire is the power becuase it it connected to the terminal with two windings.

In pic 2 the purple/orange is the power wire because there is two of them and they are thicker then the ground wire.

I am doing a TZ. Around 16 coils in all. The pics were just reference. I understand the wires. I am not sure if it mattered on the coil what tab to solder on - right, left or middle or as long as there is one on each.

If the coil needs a diode then it does matter. The power wire is always on the side with the diode band. If the diodes are board mounted, then the wires can go on either direction.

Flipper coils it matters. Other coils don't have a diode on them so it doesn't matter.

Thank you very much all of you. This helps me considerably.

BTW, use clip on heatsinks when soldering wire connections and particularly coils in general.
Clean the lug holes and get a good wrap hook with the wires through the holes.
It prevents damage to the windings, lugs, and diodes and makes soldering faster and easier.

Wondering why a coil locks on, will not hold power, does not work or burning up a new coil diodes will make you upset and you will have to do work all over again...

Thanks, I will make sure I do this.
