So are you saying that anytime someone jump starts a car they are risking explosion by removing the jumper cables? Same battery charging... same risk of sparks.
Seems a little over the top to me.

If you had ever witnessed a battery explosion, you wouldn't be so sure. In fact, you wouldn't have posted that.
It is recommended practice to connect the ground to the dead vehicle last, and disconnect it first, using a clean chassis ground rather than the negative post of the dead battery.
The other important reason not to disconnect the battery of a running vehicle with an alternator in the charging system is a high percentage of the time, damage ocurrs to the alternator.

I saw a battery explode once. We stopped work on the house we were building to eat lunch. Bulldozer operator parked about 50 feet from the porch where we were and ate with us. He got back on the dozer and when he turned the starter switch one of the two batteries exploded and blew the battery compartment door open. Really scared us all. No one was hurt, but it took several buckets of water to flood the acid from the tractor. I think about that every time I jump start a vehicle.

I haven't ever witnessed a battery explosion, and I've jumped a lot of vehicles. Now that you mention it, I do realize that the proper procedure is to connect the negative ground somewhere away from the battery. I had never thought that it would be to prevent explosions.
yes i did catch the fact that he said alternator, and i am aware that this tractor any was 6v orginally. whether 6 v or 12 v alt or generator, test for drain is the same. thats why i referred to the delco alternator, i have changed many 6v to 12v, and thats the easiest to wire up, cause of the internal regulator. any parasitic drain seen on meter, will be negligible,because there are no keep alive circuits on this tractor, but a test light, light bulb whichever you choose will do a fine job. i have seen many times the contacts in external regulator stick and be the cause of batt drain. and yes please be aware, booster cables have been the cause of many batteries to explode. RickB gave the correct procedure to make the last connection to hook up and the first to disconnect away from the battery on a grounded part of the chassis.first one i saw explode made a believer out of me. best regards. referring to delco alt, i should have said thats the cheapest with an internal reg.
