I made some progress on the magneto. The coupler is made, as is
the new mounting plate, and it’s bolted up. Right now, I’ feel no further
ahead of having a working outboard though!
It seemed to have good spark on the bench the other day by just
turning the armature by hand (without the impulse attached).
I have to crank the Wisconsin’s flywheel a pretty good clip to get any spark
right now. The mag seems grounded to the motor okay, according
to my "buzz box".
I also believe I got the timing off, as when I had the mag hooked
up with my "buzz box" determining at what rotor position the
mag would "fire" to attach the drive coupler in the correct position,
I must have been turning the magneto the wrong direction.
I can fix that by drilling and tapping a new hole for the set-screw
to ride on the flat on the armature shaft.
I presume that testing this type of mag with my buzz box (9 volt battery)
would do no damage to the magneto / coil, but I sure got a buzz
when I accidently touched one lead…… got my attention!
The magneto still has the "old" condenser yet, as I don’t know what
to replace it with. It tested at .45 mfd or so. Seems "high" for
any condenser. I haven’t found any specs as to what the rating should
be for this mag. The Bendix part number is…….
10-58224Y
UPDATE: I went thru the Mertronic manual again, and didn’t see
my condenser number listed, there was a condenser listed for
"H Series" magnetos, part number 10-82104, rated at .15 mfd’s.
My magneto is a model H1-4, so maybe close enough?
I emailed a magneto rebuilder, but heard no response back.
If I can’t find the information, I’ll just replace the old mag with
a .22 cap and see what happens.
At this point, I rather not re-design a coupling in order to use
the Bendix’s impulse coupling, but suppose that’s an option.
Another option (I think) would be to turn the magneto into a distributor
and hook up with a battery and external coil.
All for now.
