If it is a standard mag. take the wire off at the mag. and give it a try. You are correct it is a wire going to a switch to short out the mag. If it don't start right up we'll give it another go.

Dick,
I had a similar problem with my B while mowing. Acted like someone hit the kill switch on the mag.
I messed with it a while, checking what I thought was everything and finally gave up and took it to Frankie Lynch over in Moody, Tx. Frankie must be 85 years old and can fix nearly any part of a mag.
He cleaned the points, found that someone had left out a washer under the screw that holds down the points spring and she started right up! Lesson learned: check the simple stuff first and spend time looking at the details. The missing washer allowed the screw to extend too far and was keeping the points from opening fully, causing them to burn just enough to not make good contact.
After the fix it would shoot a hot, blue spark over 1/2".

Phil

Thanks for the quick response and help. It just started snowing hard again and I'm putting in new points as soon as the misses gets home to watch the baby. Hope it is something that simple.

check the wire to the from the coil to the points where it goes through the distributor casing. This is a wear spot. Also make sure that you have voltage to the + side of the coil.

Sorry, You did say you had a mag so my advice is null and void

Phill,
The B that I just completed had that kind of setup with a coil bolted under the hood with a wire going into the mag through a drilled hole in the top of the mag. I tore it apart for the good parts in it. I have also had mags quit for points failing to ground out properly on closing. I hope gets back to us with his findings because he did say that he heard a shorting sound. For his sake I hope that is was a short.

I've seen a few mags that had died and been used as a distributor with battery power coming in through the old grounding wire. If it won't run with the wire off, that's a possibility. also check to see if the ground wire is grounding somewhere it shouldn't be. FMJ mags also had occasional problems with the magnetic rotor inside coming loose and screwing up the timing, however this is rare. Hope this helps.

Today's Featured Article - On the Road with Dave Gohl: Deere Departed Friend - by Dave Gohl. Have you ever had to part with a dear friend? It's not easy. If it's due to death, your feelings could be in disarray for days, months or even years. Even now after almost 4 years, I still miss my dad. I remember when I was a kid my dad sometimes would tuck my brother and I in at night and we would ask him questions about his childhood on the farm. To this day, it's some of the best stories I've ever heard. And now, I'm so glad that I asked those questions, and if I were a little smarter i ... [Read Article]
