Pappy said: (quoted from post at 00:12:57 12/09/13) I am familiar with magnetos and distributors, but have a problem. I"m testing a Farmall 200 Distributor as a spare unit. I hook it up with a 12 volt coil and a 12 volt battery charger and I use the distributor points as a switch only. I can get a 3/8 inch blue spark (flame) from the coil wire to ground when I spin the distdributor by hand, but when I connect the coil wire to the center terminal of the distributor, then connect a spark plug wire to one of the spark plug terminals, I can only get a 1/16 inch weak orange spark to ground. I am loosing my spark within the distributor. The distributor has new points, new rotor, new cap, properly adjusted points, and is very clean. What am i missing?? I have the distributor mounted in a large vise with good ground. My battery charger negative is connected to the bottom flange of the distributor which is mounted in the vise. Maybe I am suffering from the CRS ailment. Any Thoughts will be appreciated. Like i said, it is a spare unit, but I would like to have it ready.
Are you absolutely sure that your 'test' direction of rotation is the same as in-tractor direction of rotation? Explain: If you turn it opposite the direction for which it was designed, it fires the coil when the rotor is in between cap posts, not when rotor is aligned with cap post.
