Huh weird, I'm the mod who fixed the image display in your first post, not sure why it isn't appearing there anymore, so thx for reposting.

Anyway, this link provided in the prior reply should cover everything you need:

If you're replacing an original canister-style coil with this transformer-style coil, and if the new coil doesn't come with a mounting bracket or ballast resistor (looks like a pinky-sized white ceramic bar, external to the coil itself), that may explain some of the problems you're having.

I'd recommend a Herko B108 coil, comes with the bracket and ballast resistor included, cheap and easy to get off eBay:

BTW, I found the wire routing was easier/tidier when I disassembled the Herko's mounting bracket and then reassembled it with the coil flipped around facing the other direction.
