Default Webster CM help

I have a Webster CM that has weak spark. I usually don't mess with mags, just send them out to be repaired. But I feel like tackling one and this happens to be the one I'm working on. I have charged the mag and when spinning it with the springs off and dragging the ignition wire across the case I get a very faint spark. But with it mounted on the ignitor I get nothing. Everything seems to be set up correctly. I have not put the volt meter to it yet. I did notice with the top cover off that the wire coming from the coils only has one maybe 2 wires attached to the block (that's all that is left to the wire). I will fix that and see if that helps. Any other suggestions to what I should do or look for?

Thank you
Chase

Make sure mag bracket isnt grounding through mica tube or washers. Also make sure wire clip makes good contact with stationary point shaft. This has been the number one problem I have encountered with Webster set ups.

I will check that all. The mag and bracket both look to have been rebuilt recently. Mica looks fairly new. I guess this is what baffles me. It all looks to have been rebuilt.

Make sure when it trips that it is opening the ignitor points. That is adjustable as well

Chances are the inductor rotor shaft is in backwards!,, the wide laminations are at 2:00 and 8:00 with the key way down looking from the igniter side of the mag it seems a lot of them I get to fix are wrong.

I know for sure the the key way faces down on the ignitor side of the mag. I had the back cover off looking at the internals and know the key way does face down and that the laminations are at 2 and 8.

Thanks Chase

So I have done some reading from the archives. I have charged the mag, checked to make sure that everything is set up correctly. Points open when they should open, mag trips when it should when its on the engine. The armature is in correctly. Coils look to be in good shape, I have not put a ohm meter on them yet. When mag is at rest the inductor rotor is in line the way it should be and trips at 45 deg. Mag base and bracket are clean so should be getting a good ground. Bearings are good, everything is tight.

With checking everything I found I needed to check. I still only get a very weak spark at the points. Best way I can describe the spark is that is is about equivalent to the spark of static electricity. Charging the mag did not seem to help, but when turning the inductor rotor I can feel a decent amount resistance from the magnets.. So what all does this leave? Coils?

Thanks Chase.
