Lockwood 72T Coil Removal

[Buccaneer]

Tim, it looks like you’re off to a good start.
I can’t imagine why that coil would need any support,
being it’s suspended on a sturdy laminate, and it
appears that it’s not going to slide around either.

Tubbs, I appreciate you posting these instructions.

Today I’ll put the the flywheel on and verify spark at each plug.

Multimeter showed good continuity across primary & secondary.

Be careful not to have the magneto too far
advanced  as this thing can hurt you.

Not to worry too much about the capacitors… the real high quality ones are +/- 10 % on rating, I would guess that the run-of – mill caps that are used on our motors are more like +/- 20%

Testing:

I’m not detecting any spark at either plug. Held the spark plug connector during flywheel rotation and didn’t feel even the slightest trickle.

1. Primary & secondary verified with multimeter
2. Filed points
3. Tested with both new and old condensers
4. Tested with spark tester and new plug
5. Scratched head

I guess I’d check the simple things first.
Are the points accidently grounded?
Condenser bad?
Are both sparkplugs grounded when checking spark?
Points opening okay and gapped correctly?

Prepare to be boarded!

I have experienced this when doing these
coil substations as have others.
With the spark plugs out and both plug wires
grounded to the motor, Spin the motor over with
a drill or pull the motor over as fast as you can
about a dozen times with both plugs grounded and
watch for the spark. I don’t under stand it and
cant guarantee this will help but it has worked for
me. Here are some of replies from others who gave
it a try.

In the above post it should say – with both
spark plugs grounded to the motor – not plug wires
grounded to the motor – however that still may work.

In addition to the things Buccaneer listed I would disconnect the kill switch and add insulating tape to protect against arcing from soldered coil connections to flywheel.For comparison here is a pic of my mag plate.This set up has been run successfully many times and produces a spark that will jump more than 1/4”when pulled by hand.
