All of a sudden, I cannot put the positive ground battery cable onto the battery post because of severe sparking - big time, like a welder! What has happened? Could the starter have gone bad? Has the wiring shorted somewhere?

I am hoping this brings closure to my electrical short problem on my G, however the cause is still unclear. As suggested by participants of this forum, I disconnected everything except the starter and I still got the sparking when I attempted to place the positive ground on the battery post. I removed the suspect starter and took it to a shop that repairs them. In a minute the nechanic told me my starter was just fine. That puzzeled me, but what could I do. So I put the starter back on, but first removed the positive ground cable from the tractor frame and ground through the paint better to assure a good ground. That must have done it, because no more sparking now when I put the cables on the battery. Thanks to all who helped me with this.

Let's start from scratch. I am a tractor mechanic. Dusconnect thebattery cable from the starter switch. Hoook the cable back up to the battery. Now, remove the main power feed wire from the same starter switch. Now, touchthe cable to the starter switch post that you just removed it from. No arc?. Now, touch the main power feed wire to the end of the hot cable. Arc? disconnect the Bat wire from your regulator cutout, whichever that particular tractor has. I had one, but, don't remember. Touch the main wire to the cable again. You should have the picturenow. Keep disconnecting ONE WIRE AT A TIME, until you finally make the disconnect that stops the arcing. There's not that many wireson a G, so it shouldn't take much time.

Gary: I am not a mechanic, so please understand. By MAIN POWER FEED WIRE, do you mean the cable from the battery to the starter switch or is it the wire from the starter switch to the ammeter?
