Coil wires... Green and Black

[55'Fleetwin7.5]

I removed the old coils and replaced them with Sierra units. I just can't remember which wire goes where... The new unit has a green and black wire... one goes to the points (which color?) the other goes (where?). My manual is black and white... no help.

Thanks in advance.

Also, what if any lube do you put under the armature plate?

Put the Black lead under one of the coil mounting screws, the Green lead goes to the condenser/point set.
Lightly grease under the armature ring.

Dress coil wires and condenser wires so as not to get fouled in the flywheel.
Rotate crankshaft and align key way with point set rub block and set point gap for .020. Rotate crank shaft 180 degrees, align key way with rub block and adjust second point set to .020.

Align the coils so that they rest flush on their mounting bosses. Make surface A flush with surface B.

Re: Coil wires... Green and Black

Thank you. What type of lubricant is recommended for armature plate and various linkages... Is White Lithium ok? or is there something else you like...

I installed new ignition wires. I put in the small boots that came with the new coils. Tight fit. What is a good rule of thumb for how much wire should "stick out" from under the armature plate... 1/4"? 1/2"?

Last... How many pounds of torque when reinstalling flywheel... 125lbs.?

Thanks,
Tom

A great rule I read somewhere is to replace the coils one at a time, so that you always have a template for installation. Remove only one coil, and use the remaining coil as a guide for what connects where, wire routing, etc. When the first coil is installed then remove the second one, and your newly installed coil now acts as the guide.

What type of lube would you suggest? is white lithium ok? Also... Wondered about how much new spark plug wire to leave when replacing coils... the old ones were a slightly different design. I left about 1/2" to 5/8" and it was a bit tight... Thoughts?

I wouldn't worry about the tight fit. As long as you've got good spark because your wires are making a good connection to your coil, then you're fine I would think. I'd rather have tight than loose. I usually wind up with about 1/2" at least. The torque on the flywheel nut is 40 to 45 ft.-lbs. I couldn't tell you about the grease, sorry.
Good luck,
JBJ

Ok... How do I check for spark? What is the best method? It can only take place with the flywheel on and I will take an alligator clip and ground one wire by clipping it on the transom mounting bracket.... Then what? Do I hold the other spark plug wire cap near (about a 1/2") the other plug? Then can I turn the flywheel with a ratchet? Does it need to be fast? Let me know, ok?

Re: Coil wires... Green and Black

No, the plug wires don't arc together, if that's what I understood. The one that you're testing will arc to ground about 1/2". A spark plug tester is the easiest and most reliable way to test it it's about 7 bucks at an auto parts store. I have seen people take an old plug and bend the electrode back to about a 7/16" gap and alligator clip the outside of the plug to ground, but I don't know how reliable that is.

With a good ignition system I hand tighten the big nut and then turn the flywheel by hand to get a good spark on the spark tester and do both sides, once it all checks out and there seems to be no rubbing, I torque it down.
