| The picture on the right shows a Bosch flywheel
magneto/generator taken from a Fichtel & Sachs 98 cc two-stroke engine.
The back plate is stamped with the part number 327/36Z, but the
principles described below no doubt apply to many other models of Bosch
magnetos and other makes too.
The original condenser is not shown in the photo, but was fitted in a
recess between the ignition coil and the right-hand generator coil.
The live wire of the LT winding in the ignition coil is connected to
the static point plate, which is therefore live. The moving point is
earthed, and its spring is attached to an anchor post which passes
through, but is isolated from, the live static point plate. |
 |
| Read through all of these notes before you
start cutting and drilling your EasyCap, and make sure that it appears
that the EasyCap will fit. For example check that there is enough space
between the static point plate and the moving point arm. |
|
| With the moving point and its spring removed, the spring
anchor post and another clamping screw for the static point plate can be
seen more clearly. |
 |
| |
|
| With the anchor post, clamping screw and upper
insulating plate removed, this picture shows a second lower insulating
plate between the live static point plate and the back-plate. Also,
there are insulating sleeves in the holes through the static point
plate. The upper insulating plate will be replaced by the Universal
EasyCap, after the EasyCap had been shaped and drilled. |

| If you click on the picture to the right, it will open a
template in
Adobe Acrobat .pdf format. Print it out, making sure that you use the
print dialogue box and that the page scaling is set to "no scaling" or
"100%" so that it comes out the correct size. |
 |
| |
|
| Check that the template seems to be correct for your
particular flywheel magneto, and if so shape and drill the Universal
EasyCap accordingly. If the template doesn't seem to be correct, you
will need to design your own.
It is important that the anchor post and clamping screw (earthed) do
not make contact with the bottom copper layer (live) of the EasyCap. You
therefore need to countersink the holes on the underside. |
